I'm back with another delicious recipe... my no-bake Jammie Dodger biscuit traybake! Since my Party Ring traybake, Custard Cream traybake and Bourbon Biscuit traybake have all been wildly popular over on my TikTok, it only made sense to make a Jammie Dodger one too! You just can't beat these classic British biscuits.

This one is made with a buttery, condensed milk Jammie Dodger base, a white chocolate fudge topping with raspberry jam swirled through it, and some mini Jammie Dodgers for decoration. It's super quick and easy and great for beginners.

If you're ready to get started, read my post below for my tips and tricks, step-by-step images, FAQ answers and more. Enjoy!

Ingredients

Here's everything you need to make this no-bake Jammie Dodger slice:

Jammie Dodger biscuits: You'll need 450g of biscuits for this recipe. I used the classic raspberry ones but you can use the strawberry ones if you prefer, which will also give the base a nice pink hue.
Butter: Melted butter will help to bind our biscuit base together. It adds richness and helps create that lovely texture that is a little bit like a cheesecake base. Make sure it's fully melted and slightly cooled before mixing it in with the Jammie Dodger biscuits.
Condensed milk: Make sure to use sweetened condensed milk, not evaporated milk! Learn about the difference between evaporated milk and condensed milk here. You'll need 397g or 14oz, which is the standard size of tin here in the UK.
White chocolate: This will make up part of our delicious white chocolate fudge layer. You can use any kind of white chocolate you like- I love the flavour of Milky Bar but the supermarket own-brand stuff works great too.
Raspberry jam: I added some jam to the topping and swirled it through with a toothpick. This not only adds a lovely pop of colour, but it also pairs nicely with the raspberry flavour from the Jammie Dodgers.
Mini Jammie Dodgers: To decorate the top. If you can't find the mini ones, you can of course use regular-sized ones but you might need to chop some of them up to make them fit.

Equipment Notes

High-powered blender: Or a food processor, for crushing the Jammie Dodgers into fine crumbs. This is pretty difficult to do by hand due to the jammy centre so a high-powered device will work best.
8x8-inch tin: Or a 9x9-inch tin if you're in a pinch. If you want to use a tin that's any larger than this, or a different shape, use my cake pan converter to adjust the recipe quantities too, which will ensure your Jammie Dodger biscuit slice turns out thick enough.
Baking paper: To line the tin and prevent sticking. I recommend leaving a bit hanging over the edges so you can just lift the tray bake out after it's set.
Saucepan: You'll need this for melting the white chocolate and condensed milk for the topping. If you don't have one, you can use a heatproof bowl in the microwave and melt in 30-second bursts, stirring in between to prevent burning.
Mixing bowl: A large one, to mix all of the ingredients for the base together.
Toothpick: For swirling the jam into the white chocolate topping. A skewer or the tip of a knife will work too.

How to make Jammie Dodger traybake step-by-step

Step 1: Line an 8x8-inch tin with baking paper and set it aside.

Step 2: Add 450g of Jammie Dodger biscuits into a blender or food processor and pulse into fine crumbs. Try to blitz any large lumps of jam that might be left in there.

Step 3: Add the biscuit crumbs to a large bowl along with 120g of melted butter and 120 ml of condensed milk (save the rest of the tin for step 5). Mix well to create a paste-like biscuit mixture.

Step 4: Transfer the biscuit mixture to your lined tin and press it down into place.

Step 5: Next, let's prepare the white chocolate fudge topping. Break 250g of white chocolate into segments and add it to a saucepan along with the rest of the tin of condensed milk. Place the pan over low heat and stir gently until the chocolate is fully melted.

Step 6: Spoon the white topping over your biscuit base and spread it out to the edges. Add 5 teaspoons of raspberry jam on top then swirl it in using a toothpick.

Step 8: Place your traybake slice in the fridge for 4 hours to set then remove it from the tin, cut it into squares and enjoy!

Top Tips

For a smoother biscuit base, pulse the Jammie Dodgers in short bursts rather than continuously. This will help to prevent the jam from clumping.
Mix the raspberry jam in a small bowl before adding it to your tray bake. It'll make it much easier to swirl in with the white chocolate topping.
For an extra pop of flavour, add ½ teaspoon of vanilla extract to the white chocolate topping.

FAQs & troubleshooting

How long does Jammie Dodger traybake last?

If stored in the fridge, this slice will keep well for up to 5 days. Make sure to keep it in an airtight container to prevent the base from getting soggy.

Can I freeze this biscuit slice?

Yes, you can freeze your Jammie Dodger slice for up to 3 months. Place squares into an airtight container or wrap the whole slab up in clingfilm after it's set. Thaw it in the fridge overnight or let it sit out at room temperature for an hour or two before eating. Do not refreeze.

Can I use dark or milk chocolate instead of white chocolate?

Yes. I like the way white chocolate looks in this tray bake but if you prefer the flavour of milk or dark chocolate, you can swap it out for an equal amount.

Why did my fudge topping not set?

This is usually down to either not letting it set for long enough (give it a full 4 hours in the fridge), or incorrect measuring. Read the recipe carefully as you go, because you only need 277ml for the fudge layer.

Why is my biscuit base soggy?

This again usually comes down to incorrect measuring. Make sure you're using a scale to measure the butter and the biscuits for accuracy. This can also happen if the biscuits are left too chunky as they won't absorb as much liquid. Try to blitz them down as fine as you can!

Can I make this traybake without condensed milk?

Yes, you can but it'll taste more similar to a cheesecake base than a classic biscuit slice. Condensed milk really helps to hold it together and makes it nice and fudgy. If you prefer it without, just mix 450g blitzed Jammie Dodger biscuits with 160g of melted butter. Make sure to press it into the tin firmly so it doesn't crumble.
