Jammie Dodger Blondies!

Sweet & Delicious Jammie Dodger Blondies! With a Delicious Blondie Batter, White Chocolate Chips, Raspberry Jam and Jammie Dodgers! 

Oh hey there! This is probably one of the most requested recipes I will have ever posted. I realise I say this a lot, but honestly… the other day I did a recipe request post on Instagram, and genuinely over 200 people said Jammie Dodger Blondies… the good thing is, they were already baked and ready to post on here! 

Because Jammie Dodger Blondies are something that is so highly requested, I wanted to get the recipe right! This beauty is a marriage between my Bakewell Blondies that are so highly adored already and my other blondies such as my Easter Blondies!

Blondies are similar to brownies in the fact that they can sometimes be a little tricky to bake – but honestly, once you crack it they are 100% worth the effort! Blondies are the dreamiest of dreamy when it comes to traybakes. 

I often get a lot of “What’s the different between blondies and cookie bars” questions – and trust me they are different. A cookie bar is literally just a cookie that has been baked into traybake form! You just don’t scoop them into individual cookies! Blondies, however, are a non-chocolatey or ‘white’ version of a brownie! Very similar ingredients to a brownie, but no chocolate base!

Some blondies use a white chocolate base for the recipe – and I do love that, but generally, I prefer to leave that out. You can add it in, but I find it more successful without it! I use white chocolate chips instead! If you can’t find white chocolate chips, you can just cut up the white chocolate into chip size!

When it comes to getting the batter right – it’s a fine line between mixing the mixture enough, but not overdoing it! I tend to melt my butter till it’s liquid (but not split) – and then mixing my sugar’s into the butter for about 2 minutes. I use a 50/50 mix of white granulated sugar, and light brown sugar, but if you want the lighter more classic blondie colour just use all white granulated! 

Then, I add in my eggs and beat again till smooth. The eggs will loosen the mixture slightly, but don’t worry! If you want to add in a flavouring such as vanilla, this is the point to do it!! It’s optional because sweetness comes from the white chocolate chips and the jam, but it’s also delicious if you do include it and have a sweet tooth like me!

Then, I add in the flour and the cornflour. You may ask why do you add cornflour? And that’s because it creates an epic texture. However, if you don’t have access to cornflour (or cornstarch as it’s known in other countries) then you can leave it out. I just adore it and use cornflour often in my bakes! 

By the time you have mixture your batter, it shouldn’t be incredibly thick like a cake mix, but also shouldn’t be easy to pour. I usually need to spread the mixture a bit into the tin, but it’s not a hard task. I use a 9×9″ tin – and it creates the perfect size blondie! If you use a smaller tin it WILL need longer to bake, because the volume will be too much!

I use raspberry jam in these blondies because the jammie dodgers I use are raspberry flavoured! You can use any type of jam you fancy whether it’s strawberry, seedless, blackberry conserves, lemon curd or so on! Anything you really want will work – it’s just best to stick to the same quantities so you don’t overdo it and make the mixture not bake!

You can make your own homemade jammie dodgers – but I find the shopbought regular size ones PERFECTLY fit the 9×9″ square tin, and make it one jammie dodger per slice! You can use mini ones, or a mixture, or less! It would be hard to use more though… but you get me!

When it comes to the actual baking, you’ve got to find that perfect balance. When I take the blondies out of the oven, the middle wobbles slightly. The whole tray shouldn’t wobble – but there should still be a bit in the middle as the blondies will continue to bake somewhat in the tin. A skewer test is hard, as jam or melted chocolate may come out on it – but there shouldn’t be any raw batter!

If your blondies still seem raw, you may have over mixed the mixture (just like brownies taking longer in some ovens!) – cover in foil, and bake in 5-minute increments. If you are unsure, once the jammie dodger blondies have cooled fully – you can ‘set’ them in the fridge for a few hours which will firm them up nicely, give the best texture, and make them easier to cut! 

I wish blondies and brownies were easier to get bang on – and personally, for me, they are these days, but I must have made over 1000x trays of them by now! I love these Jammie Dodger blondies SO much – and I hope you do too! x

Ingredients

  • 200 g Unsalted Butter (melted)
  • 125 g White Granulated Sugar
  • 125 g Light Brown Sugar (see notes!)
  • 3 Medium Eggs
  • 1 tsp Vanilla Extract (optional)
  • 275 g Plain Flour
  • 1 tbsp Cornflour (optional - see notes)
  • 150 g White Chocolate Chips
  • 200 g Jam (I used raspberry!)
  • 16 Jammie Dodgers

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 whisk till smooth. I beat mine for several minutes, and it starts to lighten the mixture.
  • Add in the Eggs and beat again till smooth. If you are using vanilla, add it in now!
  • 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.
  • Spoon on your jam in blobs, and then lightly swirl through - you don't want the jam to push down too low!
  • Add the Jammie Dodgers on, I line them all up next to each other!
  • Bake the Blondies in the oven for 25-30+ minutes, or until there is an ever so slight wobble in the middle. However, they can take longer. A skewer should come out clean, or with a few little crumbs, but not raw batter. See notes below!
  • Leave to cool in the tin.
  • Can be easier if you set them in the fridge, to make it easier to cut.

Notes

  • I recommend using this 9" tin!
  • I love the 50/50 mix of white granulated sugar, and light brown sugar - but you can use all white granulated for the classic lighter coloured blondie or all light brown sugar if you want them more caramel like!
  • The cornflour is for texture, but if you don't have it you can leave it out, or use 25g more flour!
  • They can take upwards of 40+ minutes in some ovens, due to using different ingredients, different ovens, different mixing methods and so on. 
  • If they turn out cakey, they are over baked - that's all! Bake for a little less time next time.
  • I use regular size Jammie Dodgers, but you can use the smaller ones too! 
  • These will last in a cake tin for 4-5 days+ 
  • I keep them at room temperature once they have been cut.

    Hi made these yesterday in an 8″ tin and like your recipe said it needed longer but then ended up being more cakey (absolutely delicious though!!!) How would you modify the recipe fit an 8″ tin either in terms of ingredients, bake time, temp?

      Hey! Ahh yes that can happen unfortunately when the tin sizes change! Typically it’s about 0.8x the recipe so if you reduce everything by about 1/5 it should be okay! Temp would be the same, time should reduce slightly x

    Absolutely love these!! Followed your recipe exactly and took onboard your notes and they seemed to pay off! Slightly gooey in the middle still, couldn’t seem to get them to set as much as the outside ones but sooo yummy!

    Thank you x

    The tasted beautiful but despite following the recipe and ingredients to a tee the mix going in wasn’t spreadable but pourable.

    Where do I need to mix more? It says mix sugar and butter for several minutes so I did 5 till it became lighter. After adding eggs and vanilla I beat again but only mly got a couple of mins as it came smooth so I need to beat this more so it firms up a bit?

    Many thanks

      How did they turn out despite the difference in how it went into the tin? If they still baked fine I wouldn’t change anything personally. If you read the recipe post I mention how I beat my butter and sugar for about 2 minutes, so it may be that you mixed it too much x

    Hi Jane,

    I tried to bake these, but they rose a little and I can’t for the life of me get the middle bit cooked. Popped some foil over so I’m hoping that works

    Made these yesterday! I over baked them as they were like sponge but every time I took them out of the oven the middle was still very wobbly and when testing them with the skewer it wasn’t clean/crumbs. Want to try them again as I want to get it right!! They were still yummy though!!

      Ahh oh no! There definitely is a fine balance when it comes to blondies/brownies – maybe reduce by about 5 minutes and see how you get on!

      I personally think caster sugar can end up cakey if you aren’t careful so as long as you don’t over bake they’ll be okay!

    Hi Jane!

    Was super excited to make these but after 40+ minutes in the oven on the right temp my jammy dodgers had burnt but the middle of my blondies was still raw mix!! Any tips? I’d love to make them again 🙂

      How thick was the mixture going in? It shouldn’t take so long, but it can do sometimes depending on the mixing process! Try and measure every ingredient exactly, and make sure your oven is the right temp! Often ovens can be the wrong temperature to what you think for example! xx

    Hey, I really want to make this but just really scared about them being under baked. If they have been in the oven for 30 minutes and they are still gooey/looking underdone, will they still be safe to eat once they have cooled? Xx

      Hey! I generally say yes they are but that’s my personal opinion!! – if in doubt, cover with foil and bake for a bit longer – and once cooled set in the fridge to firm them up! X

    Hi Jane

    I can’t wait to make these! Do you think it would be OK to add the jammy dodgers half way through baking or definetely put them in from the start? I ‘m worried my oven will burn them :)X
