A no-bake chocolate biscuit cake recipe, also known as chocolate tiffin or chocolate fridge cake.
This indulgent chocolate treat, made with digestive biscuits, chocolate, orange zest and candy, is a favourite of Prince William (and the Queen), who served it at his wedding to Kate Middleton.
I'm proclaiming this the BEST chocolate biscuit cake EVER! It's indulgent, moreish, and most importantly, absolutely delicious, as well as being ever so slightly addictive.
I'll warn you now, one is never enough.

This no bake chocolate biscuit cake is super easy to make, and a great recipe for the kids to get involved with.
One: Weight out the biscuits. I used digestive biscuits and a few gingernuts for added flavour. Crush with a rolling pin.
Two: Weigh out the chocolate, butter and golden syrup in a bowl.
Three: Melt the chocolate in a microwave. Be careful not to burn the chocolate (I usually do 20 second bursts at a time and stir in between).
Four: Add the crushed biscuits, candy (I used smarties, but Maltesers or M&M's would also work well) and orange zest.
Five: Give everything a good mix.
Six: Press the mixture into a lined tin and pop the baking tin in the fridge until set.
It's one of the easiest and quickest cakes you can make, and the hardest part is leaving it long enough to set, before tucking in. I have been known to speed up the process by putting it in the freezer, because I'm an impatient kind of girl!
📖 Variations
Anything goes really, apart from marshmallows, which are big no-no and should be reserved for Rocky Road only.
I like to put in different types of candy, and occasionally chopped nuts and dried fruit. Mini Egg Tiffin is a real Easter favourite around these parts, as is Honeycomb Tiffin at Christmas. If you're a Biscoff lover like me, you might also want to check out this insane Biscoff Tiffin too!
Sometimes, I like to put a melted chocolate topping on the top of the biscuit cake, just to make it extra chocolaty, and extra naughty. After all, there's no such thing as too much chocolate!
🥡 Storage
Well refrigerated, it will last for several weeks. If the biscuit cake is left out, the biscuits will start to soften over time. It will still taste great, but it will be a bit less crunchy.
🧊 Suitable for freezing?
Yes, it can be frozen, just tightly wrap in cling film and foil before placing in the deep freeze. It's usually not necessary to freeze it as it has such a long shelf life if stored in the refridgerater.
↔️ Substitutions
This is a great base recipe that you can vary, depending on what ingredients you have in stock.
- Replace the dark and milk chocolate with white chocolate, and make a white chocolate fridge cake (dried cranberries go well with white chocolate).
- Digestive biscuits could be swapped for Rich Tea or shortbread biscuits.
- Chopped nuts and dried fruit like apricots or raisins, could also be added to the biscuit cake.
- The most important thing is to have fun with it, because it's a really fun cake to make, and eat!
