Easy, Delicious, Biscoff Blondies with White Chocolate Chips, Biscoff Spread, and Biscoff Biscuits.

HELLO, 2020! Can we actually believe that it’s the new year?! The new decade?! I can’t believe it – and I am sure I am not alone in that. It’s been a mad decade, so here is to the new one!

What is the better way to celebrate the new decade?! BISCOFF BLONDIES! Oh helloooo that’s right – I have answered your Biscoff prayers with one of the most requested recipes in a very. long. time… Biscoff Blondies. 

I thought that I might as well make the new year start with a corker of a recipe, and Biscoff is definitely of those type of things that will work. Chocolate Orange is a little overdone now that Christmas has happened.. I need to wait at least one more week for that. But Biscoff? YUM. 

I still find that there are people out there that don’t like Biscoff, and quite frankly you guys are not welcome here. Joking – obviously. But still… how can you not?! It’s like spreadable heaven. Best way to eat it? Dunk the Biscoff biscuits in the spread and eat. 

However, I do realise that I have created some beautiful Biscoff Recipes now – including my famous Biscoff Cheesecake, and my famous Biscoff Millionaires – and I have no plans to stop any time soon. Biscoff is DELICIOUS, and you all seem to adore it as well! 

This beauty I believe is my twelfth Biscoff related recipe on my blog – and it’s something that so many of you have asked for since you adored my Biscoff Brownies so much! Switching the recipe over to Biscoff Blondies is quite simple too – as I take inspiration straight from my White Chocolate & Caramel Blondies

It’s a relatively simple swap between the caramel for the Biscoff spread, and then adding in some Biscoff biscuits for a bit of crunch and some more flavour, so it’s easy! I decided to use this type of Blondie again in comparison to my other as I prefer this one for spreads/swirls. 

You can use the smooth or crunchy spreads – it doesn’t matter which way round you choose to do it – but some people do moan that the crunchy looks a little weird when soft. I just adore the flavour though, so I don’t care what it looks like! I loveeee Biscoff. 

I recommend using this 9×9″ square tin for your traybake bakes (Affiliate link) as I just adore it! I own four of the tins, and they are all in constant use – Just line it with your chosen parchment paper, and bake away!

I also recommend using an oven thermometer for your ovens (Affiliate link) if your bakes are uneven/take a long time – just to make sure it’s actually the temperature that you think it is! Often ovens are out, which is a common reason why bakes can fail. 

Either way, I hope you love this Biscoff Blondies recipe as much as I do and enjoy!! Xx

Biscoff Blondies!

Ingredients

  • 200 g Unsalted Butter (melted) (see notes below)
  • 125 g White Granulated Sugar
  • 125 g Light Brown Sugar
  • 3 medium Eggs
  • 1 tsp Vanilla Extract
  • 275 g Plain Flour
  • 1 tbsp Cornflour
  • 200 g White Chocolate Chips
  • 250 g Biscoff Spread
  • 100 g Biscoff Biscuits (chopped)

Instructions

  • Preheat your oven to 180C/160C Fan and line a 9x9" square tin with parchment paper.
  • In a large bowl, add your melted butter and sugars and beat till smooth.
  • Add in the eggs and vanilla and beat again till smooth.
  • Add in the flour and cornflour and beat till a thick blondie mixture is made - it really doesn't take long to create this mixture!
  • Add in your white chocolate and fold through!
  • Pour the mixture into the tin, and spread. Dollop on the biscoff spread and lightly swirl through the blondie mixture.
  • Sprinkle on the chopped biscuits!
  • Bake the Blondies in the oven for 25-30+ minutes, or until there is a slight wobble in the middle. (See notes below)
  • Leave to cool in the tin, or on a wire rack.
  • As an optional extra, you can 'set' your blondies in the fridge for an hour or so to help with the texture! ENJOY!

Notes

  • I've updated the butter quanitity to be 200g rather than 250g as it was occasionally being greasy for readers - if you liked it at the 250g quantitiy you can still use it!
  • The bake time can vary - please make sure your oven is on the correct setting, and check from 22+minutes and onwards till they are baked! These took 25 minutes in my fan oven. 
  • If they turn out cakey, they are over baked - that's all! Bake for a little less time next time. 
  • One top tip is if they've been in for the 25-30 minutes, and you're still not sure, let them cool outside of the oven fully and then put them in the fridge for at least an hour to 'set'. It can firm them right up! 
  • These will last in a cake tin for 4-5 days+ 
  • I keep them at room temperature. 

ENJOY!

    Can you use crushed chocolate digestives on top instead of biscoff? would that taste nice with the biscoff spread?

    • Jane's Patisserie on August 4, 2021 at 1:49 pm

      That should be very tasty!

      Sorry Honor to jump on your reply post.

      Hi Jane, the comments to you for this seems to have gone missing so could only jump on another’s apologies!

      I’ve loved making other blondies of yours and thought of using this base for Nutella blondie instead as my daughter is Nutella crazy! Would I use the same amount of Nutella as the Biscoff (won’t be using biscuits on top)? Also I have brown sugar and caster sugar but not enough granulated – would it be ok with all brown sugar or s bit of caster & brown sugar do you think? Many thanks for your advice and time x

    These are the most amazing blondies I’ve ever made, had both but compliments!
    If I was to double the recipe, would I just double the cooking time?

    • Jane's Patisserie on July 2, 2021 at 9:48 am

      Aww thank you so much! You need to bake them in the same size tins so I would bake the recipe twice – not double it xx

    Hi Jane,

    when you mention about mixing the butter and sugar until smooth do you mean mix it until the butter has completely dissolved and blended with the butter to make a thick consistency?

    Thank you!

    • Jane's Patisserie on June 28, 2021 at 3:55 pm

      Hello, beat together enough like you would a creamy butter and sugar for a cake mix x



  4. Sinead on May 12, 2021 at 8:44 am

    What are the measurements of each brownie to make 16 of them?

  5. Aimée on May 8, 2021 at 11:05 pm

    Hi Jane

    I am vegan … would it work with swapping out the eggs for flax seed egg?

    Thank youuu x

    This recipe was a success! All my friends loved! They kept coming for more until it was all gone. I’m a dark chocolate lover, so when I saw the amount of white choc and sugar I was a bit scared it would be suuuuper sweet, so i reduced sugars by 25g each (added 100g each sugar instead) and I think it was perfect!!! Didn’t add as much biscoff spread but loaded with biscuits on top. I’m sure my friends will be asking me to make this recipe again.

  7. Chantelle on April 1, 2021 at 10:18 pm

    Hi Jane! I’m struggling with cutting my blondies, I used your recipe and was really happy with how they looked – no sinking in the middle! But when I cut them (even after they’ve completely cooled) the inside almost spills out. All the blondies I’ve cooked before, these and other recipes, are almost too delicate to cut properly? I’m just wondering if I’m doing something wrong, are they undercooked? Thank you! X

  8. Nas on April 1, 2021 at 9:32 am

    Hi can’t wait to try these but I only have large eggs how many should I use?

    • Jane's Patisserie on April 1, 2021 at 11:19 am

      Hello! I would use two and a yolk x

    Hi Jane,

    I’ve seen a few you tube video that the biscoff spread is blended into the mix but yours has no mention of it. So do I just dollop the 250g of spread on top and swirl them? Sorry to be a pain

  10. Kapri on March 27, 2021 at 9:49 pm

    Hi there, American here. I did the conversations for the temp I need to use but I’m confused. Do I do 160 or 180?

    • Jane's Patisserie on April 3, 2021 at 10:24 pm

      180 is a normal oven, 160 is a fan oven



  11. Holly on March 4, 2021 at 12:12 pm

    Would it be okay to leave out the white chocolate chips? If so, is there anything that I could use instead that would work just as well? (Given up chocolate for lent, but these look delicious)

    • Jane's Patisserie on March 6, 2021 at 7:46 pm

      I would just use it without chocolate to be honest – still be tasty!



  12. Holly on March 4, 2021 at 7:17 am

    Would it make too much of a difference if I didn’t add in the white chocolate chips? If it would, is there anything I could add in instead of chocolate? Thanks.

    • Jane's Patisserie on March 6, 2021 at 7:10 pm

      It may reduce baking time slightly is all!

    Hi Jane, love your site and just starting out making cakes for our coffee shop.

    Would like the blondies a little more thick. Is it okay to add some biscuits through the mixture to make them more crunchy. Plus add some melted spread on top with the biscuits?

    • Jane's Patisserie on February 25, 2021 at 2:20 pm

      You can definitely add biscuits throughout – but they won’t stay as crunchy once baked!! The biscuits soften after baking and being out of the packet xx



  14. Victoria on February 21, 2021 at 8:54 pm

    Hi,
    is it 200g melted butter or 200g of butter then melted.
    thanks.

    • Jane's Patisserie on February 25, 2021 at 2:25 pm

      That’s the same thing – you need 200g, and it needs to be melted!



  15. Sophie on February 13, 2021 at 9:17 pm

    Hi Jane. Would you use a stand mixer for this or is it best to mix by hand? If using a stand mixer, what attachment should I use? X

    • Jane's Patisserie on February 14, 2021 at 11:12 am

      I would use the beater/paddle attachment, not a whisk. x

    I love this recipe! But unsalted butter works out really pricey when you make a big batch, can stork be used instead?

    • Jane's Patisserie on January 31, 2021 at 11:47 am

      Yes, for blondies/brownies stork can be used! x



  17. Zainab Jaffer on January 22, 2021 at 2:48 pm

    Hi, thank you for the wonderful recipes! Wanted to ask what to do with regards to the melted butter? I don’t see any reference to it in the notes
    Thank you

    • Jane's Patisserie on January 22, 2021 at 8:50 pm

      The melted butter is used in step two of the method.

    Loved this recipe!! Although how do you place the 250g of biscoff spread on top? I tried to do it before putting it in the over and most of it dried up and blended in with the blondie x

    • Jane's Patisserie on January 15, 2021 at 10:23 pm

      It may be that you swirled it too much – try and dollop it a bit more and swirl a bit less!

    Hi Jane, I was wondering if it is possible to add the biscuits half way through baking, while the mixture is still gooey to prevent them from burning?

    • Jane's Patisserie on January 11, 2021 at 8:48 pm

      You can do, but you would need to be really quick as ovens shouldn’t really be opened half way through baking. x

    These taste absolutely amazing ! Had a heart attack at the amount of biscoff that goes into it though! As soon as I eat one I think of how much calories it’s going to be 🤣.

  22. Edwina Mckay on December 16, 2020 at 3:27 pm

    Loved making these but they came out Cakey any reason to why ? I did everything by the instructions and ingredients

    • Jane's Patisserie on December 16, 2020 at 6:43 pm

      Every oven is different so instructions are only a guide – this just means they are over baked.

    • Jane's Patisserie on December 7, 2020 at 8:29 pm

      Yes they are! The biscuits will go quite soft though so they’d be best left off unless you don’t mind it x

    • Jane's Patisserie on November 29, 2020 at 12:57 pm

      It may be that your oven is too hot – it may be worth leaving them off the top and mixing them in a bit more instead? x

    Love your recipes, but can I ask…. how come you use more flour in this blondie recipe than in some of your others? ie your lemon and blueberry or your white chocolate and raspberry? I’ve made them all and love them but I just wonders why they differ in ratios. Many thanks xxx

    • Jane's Patisserie on November 10, 2020 at 11:32 am

      They are just two completely different methods is all (which is explained on one of the posts) x

    I made these yesterday and just as I was about to put them in the oven, I realised I hadn’t added the light brown sugar! Adamant not to waste the ingredients, I scraped off the biscuit topping, poured the mix back into the bowl, added the brown sugar, blended and reconstructed. So I didn’t have swirled biscoff spread as shown in Jane’s pictures and they were light brown in colour, but they were fine!

    Hi Jane, I’ve made these twice and they’re sooo good but I was just wondering if the pieces surrounding are meant to be a bit more cooked than the rest of the Blondies? I can never seem to make them less cakey but the rest of the Blondies are amazing.

    • Jane's Patisserie on September 11, 2020 at 8:48 am

      There will always be a smidge of blondie that will bake more, but that happens to all bakes. It may be worth changing the temperature slightly to see if it helps, but also making sure you are careful when making the mix too! xx



  30. Laura on August 26, 2020 at 10:18 pm

    Hi.
    Can I possible make up the mixture and set in a baking tray but cook later in the day? Thanks

    • Jane's Patisserie on August 27, 2020 at 4:01 pm

      Generally I would never recommend that in baking x

  32. Essie on July 25, 2020 at 9:10 am

    Hi Jane,
    I made this recipe and ended up leaving them
    In my gas oven for 30 mins. I have an oven thermometer. I wasn’t sure when to pull them out but I read on your notes after 30 mins to let them
    Set in the fridge and for them to have a slight wobble in the middle. I did this but I found that the middle 4 slices were almost raw. I followed your recipe to a T and don’t know what I did wrong.

    • Jane's Patisserie on August 2, 2020 at 6:33 pm

      I haven’t baked these in a gas oven before, so it may just mean they needed longer – that is often the case with brownies/blondies! The best way to see if is if they have an ever so slight wobble to them but nothing major, and then leave them to cool fully in the tin (you can also set them in the fridge to help firm them up to cut!) X



    • sharon on August 12, 2020 at 10:57 pm

      same here, just made them today and middles section under cooked after at least 30 mins?



    • Jane's Patisserie on September 14, 2020 at 8:57 pm

      As mentioned it can take long in some ovens – just cover with foil and bake bit longer..!



  33. natalie on July 19, 2020 at 10:17 pm

    Hi Jane
    I’m going to make this tomorrow for a “birthday biscoff treat“. Could I use a round 8” cake tin instead so it looks more like a birthday cake?! Or is it best to stick to the square tin? Thank you xx

    • Jane's Patisserie on July 19, 2020 at 10:46 pm

      That may make them too deep, so they may struggle to bake properly – but otherwise it should work!

    Hi have just made these and they are A M A Z I N G !!!!! I used 50:50 milk and white choc chips and also stirred a few biscuit through like Janes brownie recipe. I used a silicone 9X9 and had to book for 35 mins which gave a nice crisp edge but super gooey middle. Can not wait to try more of Jane’s recipes!

      Love the recipe – white chocolate and biscoff are a great combination. However, what does the Cornflour do? The blondies have a slight doughy texture – and I wondered what would happen if I remove the cornflour? Thanks!



    • Jane's Patisserie on August 4, 2020 at 5:28 pm

      The cornflour creates a nicer texture in my opinion (the doughiness wouldn’t come from it, that’s typically baking/mixing) but you can leave it out as mentioned on the post if you wish!



  35. Maddie on July 5, 2020 at 4:43 pm

    Hi Jane!
    Out of interest which unsalted butter do you use? I normally use lurpak but wanted to switch to stork butter but not clear as to if it’s unsalted or if it’s just good to use in sponge cakes rather than brownies/blondies and cookies?
    I trust your judgement 😂
    Thank you!

    • Jane's Patisserie on July 5, 2020 at 5:41 pm

      You can use stork for blondies/brownies/cookies/etc – the only thing you shouldn’t use a spread for is buttercreams!



    • Maddie on July 5, 2020 at 5:53 pm

      Ah thank you so much for your help!! X



  36. Greta Johnson on July 4, 2020 at 10:06 am

    Hi, when setting the brownies in the fridge do you have to wait for these to cook first? X

    • Jane's Patisserie on July 4, 2020 at 7:04 pm

      I would wait for them to cool slightly yes!



  37. Diane Haimeed on July 3, 2020 at 2:22 pm

    Can you recommend a good brownie tin pls

    • Jane's Patisserie on July 3, 2020 at 3:54 pm

      Any 9×9″ square! x



    • Lee on July 5, 2020 at 2:01 pm

      Hi jane, I have a 13inch by 9 in tray, how much would you increase the ingredients by? I was thinking 10%?



    • Jane's Patisserie on July 5, 2020 at 3:48 pm

      Typically for the same depth you’d add on another half!



  38. Liv on July 1, 2020 at 4:59 pm

    Hey,
    I just made these and they taste amazing.
    I make brownies a lot but this is my first ever batch of blondies. I cooked them at 160 fan for 25 minutes and they were still extremely wobbly and were definitely not cooked so I cooked them for another 5 minutes, still too wobbly to take out so left for a further 5 minutes and I took them out even though they were still wobbly because I thought they may continue to cook in the tray and be a bit better.
    I left them to cool for an hour and a half at room temperate and the outside of the brownie was cakey and overcooked and then the middle wasn’t cooked at all, I picked a brownie up from the middle of the tray and it collapsed in my hand where it was soggy and I had to throw it away.
    All of my measurements were right, I didn’t overmix just very quickly blasted the mixture with a hand blender for 10 seconds before adding the choc and for some reason it didn’t turn out anything like your photos.
    Could you think of any reasons why?
    I really want a fudgey brownie, but these turned out both cakey and runny for me 🙁

    • Jane's Patisserie on July 1, 2020 at 7:38 pm

      I would say the issue could be the hand blender – I don’t recommend using those to make mixture at all! You should mix your butter/sugars for about 2 minutes, and then mix everything else in just till it’s combined. The mixture is thick and lovely!



  39. Steph on June 27, 2020 at 6:11 pm

    I don’t eat chocolate, and I’ve been looking for some blondies to try, and I love biscoff! Can I just leave out the chocolate, or do I need to add something else in?

    • Jane's Patisserie on June 27, 2020 at 7:25 pm

      Hey! Yes you could just leave out the chocolate chips xx



  40. Maria Woodcock on June 27, 2020 at 2:17 pm

    Hi Jane,

    Can you replace the granulated sugar with caster sugar?

    Maria x

    • Jane's Patisserie on June 27, 2020 at 7:33 pm

    Love these so much I’ve baked a second lot in a week! Although started quite late tonight & they’re not yet cool (hottest day of the year! 🙈) have you any tips in future regarding them cooling? Are they ok overnight in the tray to cool uncovered? The tray seemed warm so I was vary to wrap in case it made them soggy, equally don’t want to dry them out. Thanks so much in advance x

    • Jane's Patisserie on June 24, 2020 at 8:48 am

      Hey! Ohh yes baking on hot days can make things take longer haha! I would just leave it out, but cover the top with a clean teatowel maybe? Putting them in the fridge can also be fine as it can create a nice texture (as long as they aren’t over baked!) x



  42. Sam on June 22, 2020 at 5:01 pm

    Hi Jane, I’m loving all your recipes and slowly but surely making my way through them 😄

    I have read previous comments that have asked about using a white chocolate bar chopped up instead of white chocolate chips and it will work out fine but I was just wondering if you could tell me what brand of white choc would be best? Milkybar, green and blacks, supermarket own brands, white chocolate buttons….there’s just too much choice which means even more reason for me to mess up😬

    Any help would be greatly appreciated! Thanks

    • Jane's Patisserie on June 22, 2020 at 9:14 pm

      Hey! If I can’t access chocolate chips, I usually just chop up a supermarket own brand! Xx

    Hi Jane, I have tried many recipes from your site. They are awesome!
    Instead of light Brown Sugar can I use Demerara sugar.
    When I baked them in a rectangle tin foil it went flat.
    Thank you for your wonderful recipes!!!

    • Jane's Patisserie on June 22, 2020 at 9:20 pm

      I would use all granulated sugar instead of light brown – and the sizing of the tin may have been a different volume!



  44. Charis on June 18, 2020 at 11:54 pm

    Hi Jane,

    I love all your recipes! They work so well.

    I have seen other similar recipes for this type of blondie who have used only dark brown sugar – does this work/taste the same as the above recipe?

    Thanks!

    • Jane's Patisserie on June 19, 2020 at 8:27 am

      Hey! So it tastes different – dark brown sugar has a much deeper more treacle-like flavour, and it will also look darker (but other than that, it works the same!) X



  45. Sam on June 17, 2020 at 9:55 pm

    Hi Jane, just wondering if I’m under cooking these lush blondies? Are they suppose to be quite gooey? I cook them for about 27ish minutes. Let them cool down completely all day and they seem quite undercooked but not sure if it’s just the gooey texture they’re suppose to be? The outside is more cakey it’s just the inner/middle bit, so worried if I was to cook them for any longer the whole lot would be more like a cake! Any advise would be much appreciated. Thank you xxx

    • Jane's Patisserie on June 18, 2020 at 7:32 pm

      Hey! So they are meant to have a brownie like texture – so sorta gooey, but not raw! It may be that your oven is too hot, so maybe lower it so that the outsides bake less quick, but bake for a bit longer! x



  46. K on June 16, 2020 at 8:00 pm

    Hi, I left these in for 30+ mins, the top started to burn and I’ve had them cooling for a couple of hours. I went to take them out of the tin and they don’t even look cooked at the bottom 🙁 what could’ve gone wrong? X

    • Jane's Patisserie on June 16, 2020 at 9:15 pm

      That sounds like your oven is too hot – they definitely shouldn’t burn at 30 minutes. It’s best to lower the temp, make sure your batter is nice and thick (don’t over mix) and bake for a bit longer if you need! Then, set the in the fridge for a few hours if you want! x



  47. amber on June 16, 2020 at 12:00 am

    Hiya! I’m wanting to be greedy and make two different flavours of brownies or blondies (haven’t chosen yet🤣)… could i make the batter, halve it then fold in the two different flavours then cook together in the same tin if I’ve explained that properly? 😳😆 Thank you in advance😊!

    • Jane's Patisserie on June 16, 2020 at 10:27 am

      Hiya – the theory is that it’s fine, but sometimes they can take different times to bake so it could be a little problematic, but normally would be fine! X



    • amber on June 16, 2020 at 2:47 pm

      Thanks Jane, I may try triple chocolate and chocolate orange in one tray then biscoff and bakewell blondies in another. Thank you for your reply. X



  48. Leah on June 11, 2020 at 4:06 pm

    Hi Jane,

    Can you freeze these?

    Leah

    • Jane's Patisserie on June 12, 2020 at 10:11 am

      Yes you can!



    • Leah on June 12, 2020 at 10:33 am

      Thanks Jane. Not sure we’ll need to freeze them as they are going down so well! Will definitely be making these again. Great recipe! 🙂

      Hi Jane,

      I noticed you said these can be frozen… how would you recommend de frosting them? Any guidelines?

      These are lovely x



    • Jane's Patisserie on June 19, 2020 at 7:38 pm

      I would just leave them at room temp to defrost! How long it takes depends on a few things but generally it takes quite a few hours or so! x



  49. Pauline Mansell on June 7, 2020 at 3:04 pm

    Hi Jane,

    Love your site! I only have a 13 by 9in tin can you advise on amount to increase recipe by? I assume recipe listed will be not be suitable for this size?

    Thanks in advance
    Pauline

    • Jane's Patisserie on June 7, 2020 at 7:13 pm

      Hey! Yes so for a 9×13″ is 1.5x the recipe!! The baking time will also increase! X



  50. LaURA on June 6, 2020 at 6:57 pm

    HI Jane – I made these and they are still very gooey in the middle. I baked for 33 minutes and then put in the fridge after the first hour. Are these ok or do you think I should try baking for a bit longer? Thanks x

    • Jane's Patisserie on June 6, 2020 at 8:24 pm

      As you have cooled them now, it wouldn’t be wise to put them back in the oven – they’ll be fine to eat if they’ve been in that long, it may just mean your oven temp was a bit too low, or the mixture was over mixed slightly! x



  51. Simon Alexander on June 6, 2020 at 9:06 am

    I Cannot wait to try these we only have a 8×8 tin Will I have to reduce all the ingredients by much?

    • Jane's Patisserie on June 6, 2020 at 12:10 pm

      Hey! So for an 8″ tin, you want to reduce it by about 1/5 xx

    Hi, Can I use white chocolate bar rather than chips as I cannot find any anywhere?

    • Jane's Patisserie on June 5, 2020 at 10:35 am

      Yes definitely! Just chop the bar into chip size!



    • Jo on June 5, 2020 at 8:41 pm

      Do I melt the biscoff spread first?



    • Jane's Patisserie on June 5, 2020 at 8:51 pm

      You don’t have to no – I just dollop it in as it is, and swirl through!



  53. Claudia on June 3, 2020 at 10:53 pm

    I am looking to make this recipe this weekend but I am just wondering why there is so much more flour in these rather than the biscoff brownies that I have made before and they are so fudge – will these still be gooey and fudgey with this amount of flour? will using all light brown sugar matter too? or do I need to us white sugar? Thanks!

    • Jane's Patisserie on June 4, 2020 at 9:05 am

      Blondies and brownies are still very different to each other, and this doesn’t have melted chocolate in the recipe – these are definitely still fudgey and gooey as you can see from the photos! And you can use all light brown sugar, it just makes them slightly darker in colour!



  54. Lisa Aladesoun on May 30, 2020 at 7:47 pm

    I want to try a sample of this, so I’m thinking of dividing the mixture by a third, we’ve eaten far to many cakes, cookies and brownies in lockdown 😂What size tin would you recommended and bake for how long?

    • Jane's Patisserie on June 1, 2020 at 3:23 pm

      Hahaha!! A 1/3 is about a 5×5″ square so it’s much smaller – and I’m not 100% on the baking time I’m afraid as I’ve never made them this small! But I would say check at like 15 minutes?!

    My favourite recipe of all time! Biscoff and white chocolate in a gooey blondie, heaven. I’ve bought a crunch spread and was thinking to try that out. Do you think it would work just the same?

      Ahh yay!! Yes it would work the same – and still be delicious!



  56. Hannah on May 29, 2020 at 1:33 pm

    Hi Jane,
    This recipe looks gorgeous. Can i use a 11×7 inch tray instead as its the only one i have right now.

    • Jane's Patisserie on May 29, 2020 at 1:56 pm

      Hey! Yes you can – volume wise it should be the same! x

    Hi Jane!
    I wondered what you think about baking brownies in disposable aluminium foil trays that are 9” by 9”

    Do you think baking them in foil trays makes a difference to the outcome of these brownies?

    Thanks!!!! Xx

    • Jane's Patisserie on May 24, 2020 at 1:32 pm

      Hey! So sometimes they can bake a bit quicker where the foil tray is thinner – but sometimes it’s the same! x



  60. Alice on May 23, 2020 at 3:00 pm

    I’ve not baked these yet but have baked a few other things from your recipes and they have all turned out so so well!
    Just one question: I want to turn these into kinder bar/bueno blondies with some whole bars on top to decorate, would you recommend leaving the bars off the top until the last five or ten mins of baking then gently pushing them in? I’ve heard somewhere this is how others do it but didn’t know if it’s necessary?

    • Jane's Patisserie on May 23, 2020 at 5:01 pm

      Hey!! Yes for something like a bueno/kinder in these I would wait – sometimes blondies can take a bit longer to bake for some people so I’d suggest waiting!! x



    • K on June 15, 2020 at 1:18 pm

      Do I need the cornflour?

      Thanks x



    • Jane's Patisserie on June 15, 2020 at 5:20 pm

      For the best blondie, yes. But, you can use 25g extra flour instead.

    All the biscuits burnt / overbrowned and the Lotus spread hasn’t come out running like in your image. Starting burning about 8 mins in and by 15 mins they we’re all so brown – even turned the oven down! Would there be a reason for this? X

    • Jane's Patisserie on May 22, 2020 at 7:58 pm

      That sounds like your oven is way too hot – there’s no way they should burn like that.



  62. Em on May 20, 2020 at 9:40 pm

    Hi, for the unsalted butter does this need to be a block or could I use something like stork spread/ baking cake spread?

    • Jane's Patisserie on May 21, 2020 at 8:34 am

      You can use block butter or a baking spread in these!



  63. Georgia on May 20, 2020 at 3:01 pm

    Can I use Nutella spread instead of Biscoff?

  64. Afra Akmal on May 20, 2020 at 1:23 am

    Hi! I can’t get hold of any Biscoff spread, can I replace the Biscoff spread with Nutella and the Biscoff biscuits with some chocolate or something like Kinder Bueno? Thanks! x

  65. Georgia Barber on May 19, 2020 at 7:39 pm

    is there a way I can make this recipe vegan? My mum and stepdad love biscoff, but are dairy intolerant

  69. Bonita on May 16, 2020 at 8:42 pm

    Hi Jane,

    I use so many of your recipes and they are always so reliable!

    Quick question, how do I avoid the outside baking more than the inside? I set my oven to 160 but seem to get a bit of a thick bit on the edge!

    Also, does adding the cornflour right at the end so that the mixture stays loose change the bake at all? I think that might be were I am going wrong! First time I made them the batter went really thick before going into the tin, second time I added the cornflour right at the end and the mixture stayed runny?

    Hope you can help!

    • Jane's Patisserie on May 17, 2020 at 12:52 pm

      Hey! So this will often happen with traybakes – you will always have a more baked outside than inside (same with cakes and so on!) – but it may be worth lowering the temp even a bit more and baking for a longer time instead! – also, I do recommend putting the flour and cornflour in at the same time so that you don’t over mix the mixture! x

  72. Anj on May 8, 2020 at 11:07 am

    Hi due to make this tomorrow but don’t have a tray. My options are a 9inch round cake tin or a 9x9inch ceramic square dish. Which is the best option out of the two? Not really bothered about what it looks like but don’t want the timings or anything to ruin the taste or texture! Thank you

    • Jane's Patisserie on May 8, 2020 at 12:11 pm

      The ceramic dish should be fine! I would still line it though!



    • Anj on May 8, 2020 at 2:19 pm

      Great thank you. Will the timings remain the same?



    • Jane's Patisserie on May 9, 2020 at 7:09 pm

      In all honesty it could vary slightly, as the heat will react differently to the ceramic dish over the metal tin! It’s best to under bake slightly and then ‘set’ them in the fridge for an hour once cooled compared to over bake!

      Not the best baker but I do try.
      I definitely ate one and loved the taste, the biscoff probably helped but really not sure on the consistancy, I asked someone else to try and they said the same basically seems under baked and did look it- I read your blondie posts and unsure where I’m going wrong but I didn’t want to risk taking to work 🤦🏻‍♀️ I’m a pleaser and don’t want to take stuff to others that I’m not 100% happy with.
      These were done for 40 mins in the end so not sure.
      The biscoff biscuits don’t look like to much on your pictures but on mine the 100g and 250g spread seemed alot, the biscuits seemed to cover every inch on top of the surface, I mean I’m not complaining just checking as that was the same size tray.
      This definitely is meant to be a positive post as I’m loving all your recipes just checking for more clarification on the right consistancy for future reference.



    • Jane's Patisserie on May 4, 2020 at 7:35 pm

      As mentioned in the notes these can take longer in some ovens! One top tip is once you think its basically there, leave them to cool and then ‘set’ them in the fridge for at least an hour and it will firm them right up! The measurements are definitely correct, but you can always use less if you prefer!



    • Emily on May 11, 2020 at 9:36 am

  86. Sarah on April 3, 2020 at 6:04 pm

    I’ve just baked these and they are almost cooled now. I ended up cooking for the full 30 minutes as they were super wobbly and looked like it was just going to fall apart and now it seems dry and hard on top so think I’ve definitely over baked them!

    One thing I noticed is that in grams it says 250g of butter which is what I used but then if you convert to ounces it works out as just under 200oz. Is this a mistake or have I used too much butter? I followed the recipe exactly so not sure what I have done wrong.

    • Jane's Patisserie on April 3, 2020 at 7:36 pm

      Hey – 250g is 7.05oz as noted on my conversion button – I’m not sure where you got 200oz from! However, you made them correctly, you have just over baked them. They will be a slight wobble, but once it settles and cools it will naturally keep on baking a bit and then you get the perfect blondie!



  87. Robyn on February 24, 2020 at 3:57 pm

  89. Shelley on February 2, 2020 at 10:35 am

    Just popped a batch of these in the oven and praying they’re ok! The batter seems very thick compared to the other brownies I’ve made from your site, so just hoping this is normal for blondies (perhaps lack of melted choc?). One thing to note is I forgot to add the vanilla extract, because it isn’t listed in the method! I hope this won’t affect it too much – we’ll see in a little while!! Made so much from your website, as a novice baker they’re fail safe and always get glowing reviews. Fingers crossed for these!

  90. Savannah on February 1, 2020 at 3:29 pm

    I’m on the hunt for the holy grail of blondies! All the ones I’ve tried have been a huge let down and taste like baked cheesecake for some reason?! With no butterscotchy flavour at all! I think this was because there was melted white choc in the batter itself and also turned the bars a whitey yellow colour. I noticed that your recipe doesn’t have melted choc in the batter ajust chips added and a fab golden brown butterscotch colour once baked! Do you think the white choc is what’s causing this wierd cheesecake – like flavour?

    • Jane's Patisserie on February 1, 2020 at 9:56 pm

      Yes often I find that too! I prefer blondies without melted white chocolate in!



  91. Pawel on January 11, 2020 at 8:53 pm

  92. Helen on January 8, 2020 at 1:31 pm

    Why do you put corn flour in it?

    • Jane's Patisserie on January 8, 2020 at 2:14 pm

      Because it makes a better bake. Changes the texture, makes a better blondie. I use it in several recipes, and my cookie bars.



    • Lea on July 19, 2020 at 5:48 pm

      Hi Jane, just wondering is there an alternative to corn flour? Or what would happen if I leave it out? Can’t get my hands on it in any shops near me.



  93. Paige Mortimer on January 4, 2020 at 8:13 am

    Would you say the 9×9 covers most of the brownie and blondie recipes? I have made lots of your cakes but none of these. I want to try but need a tin.

    • Jane's Patisserie on January 4, 2020 at 7:52 pm

      Yes! I use it for probably 95% of my traybake recipes!
