Jammie Dodger biscuits are one of my favourites, I remember eating them as a child and always picking them first out of biscuit selection boxes. If you're not from the UK, they are a cookie with jam sandwiched in between two layers of biscuit. They have such a fun appearance - with the splash effect on the biscuit and heart shaped hole revealing the jam in the middle. It's no wonder they are the most popular kid's biscuit in the UK! I've incorporated yummy Jammie Dodger biscuits into these soft gooey Jammie Dodger Blondies, as well as adding some extra jam (because that's the best bit!) If you've not heard of blondies before, they are the white chocolate version of brownies, and if you enjoy these you'll love my Raspberry & White Chocolate Blondies too!

How to make Jammie Dodger Blondies
Start by melting the butter and golden caster sugar together in a pan on a low heat. Once the butter is melted, take the pan off the heat and add the white chocolate. Leave it for a couple of minutes, then stir it until the white chocolate melts into the mixture.
Add the eggs and vanilla extract and whisk them in. Then add the flour and whisk in.
Pour the batter into a lined traybake tin. Place the Jammie Dodger biscuits on top, then added blobs of jam all around the biscuits and swirl the jam around using a butter knife. Bake for 30 minutes or until golden all over.
How do you know when the Jammie Dodger Blondies are baked?
I bake them in my oven on 160C Fan for 30 minutes until they are golden brown all over like in the photo above. Using a skewer inserted in the centre doesn't give a clear indication that they are done because blondies are meant to be gooey and almost a little under cooked. Blondies are the white chocolate version of brownies and they are not like cake. They will also set more as they cool down, wait until they are fully cool to remove them from the tin. I've made these Jammie Dodger Blondies probably more than any other recipe on my blog as my best friend loves them! More than 10 times by now, and I always get the same results. If you have followed the recipe exactly and used the same size tin you can do the same. Different ovens can run at slightly different temperatures so an oven thermometer is the best way to check the temperature is accurate, you can get them for under £10. If you have a different sized tin, they will need longer in the oven. If you have changed any ingredients this will affect the recipe and they won't turn out the same way as mine.
Can you make this recipe without Jammie Dodgers?
Yes! You can make this recipe without the Jammie Dodgers, or you can use any other jam filled biscuit or linzer biscuit. Or you could even make your own homemade Jammie Dodgers, there are lots of recipes available by doing a Google search. Or you can use my Vegan Jammie Dodgers recipe!
What can you do differently?
You could use mini Jammie Dodger biscuits if you wanted to cut the pieces smaller. I like to give everyone one big Jammie Dodger biscuit per piece, but you could also cut them in half - I like to cut them diagonally when doing this. You can use different flavours of jam for example strawberry, raspberry, blackcurrant or cherry. I've also made these before using Lemon Jammie Dodger and lemon curd! You can also add white chocolate chips to the blondie batter, I've done this before at my friends request to make it extra chocolatey!
What white chocolate should you use?
The majority of times I make this recipe I use a supermarket own brand white chocolate (not the very cheapest kind, but the level above) or Callebaut callets, if you use a better quality chocolate, like Green & Black's for example, it will improve the flavour. But of course supermarket own brands are great for keeping costs down. I would advise avoiding cooking or baking chocolate, and also I don't recommend using Milky Bar or any white chocolate with low cocoa solids.
More tips for making the Jammie Dodger Blondies:
- If you can't get hold of golden caster sugar, you can also use regular caster sugar (also known as superfine sugar).
- The blondies can be frozen. Once fully cool, wrap them well and freeze for up to 3 months.
- You will get better results if you use a good quality jam
