    A no-bake chocolate biscuit cake recipe, also known as chocolate tiffin or chocolate fridge cake, which is just perfect for kids parties!

    This indulgent chocolate treat, made with digestive biscuits, chocolate, orange zest and lots of candy, is a favourite of Prince William (and the late 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 piece is never enough!

    ✔️ Why should you try it?

    Here’s why this is the BEST chocolate fridge cake:

    • Quick and easy no bake recipe.
    • Great for parties and bake sales.
    • Keeps for a long time.
    • You can vary the base recipe with different types of candy and flavourings.

    🥘 Ingredients

    • Digestive biscuits (Graham Crackers)
    • Chocolate
    • Butter
    • Syrup
    • Candy
    • Orange Zest (optional)

    🥄 Equipment

    To make the recipe you will need;

    • Large bowl
    • Rolling pin for crushing the biscuits
    • Cling Film
    • Microwave
    • 20cm square baking tin

    🔪 Instructions

    The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

    This no-bake chocolate biscuit cake is super easy to make, and a great recipe for the kids to get involved with.

    One: Weigh 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 microwaveable bowl. Melt in a microwave in 20-second bursts, stirring 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 and press the mixture into a lined tin and pop it in the fridge until set.

    Step 4-6 Making chocolate biscuit cake

    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 like Biscoff 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. 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 will be a bit less crunchy.

    🧊 Suitable for freezing?

    Yes, it can be frozen. Tightly wrap in cling film and foil before placing it in the freezer. It's usually not necessary to freeze it as it has such a long shelf life if stored in the refrigerator.

    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!

        Hi Lizzie. Glad you enjoyed them. I based the calorie info in the recipe card nutrition data on 16 slices which equated to 226 calories per slice.
