Biscoff Blondies!

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

Recipe Notes
  • 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. 
  • These will last in a cake tin for 4-5 days+ 
  • I keep them at room temperature.

    Is there anything I can substitute the eggs for? Going to try and make this for my vegan friends as they like biscoff!

    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!

    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?

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

    Cannot wait to give this bake a go!
    Why do you put corn flour in it?

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

    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.

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