This No bake biscuit cake has been a beloved dessert across European households for generations, particularly famous as a royal favorite at British tea parties. The beauty of this refrigerator cake lies in its simplicity—crushed digestive biscuits bound together with rich chocolate ganache, creating layers of texture that are both crunchy and creamy.

It actually improves after sitting in the refrigerator overnight, making it an ideal make-ahead option for busy schedules.

Step-by-Step Instructions

Ingredients:

– 400g digestive biscuits or graham crackers
– 200g dark chocolate (60-70% cocoa)
– 100g milk chocolate
– 150g unsalted butter
– 4 tablespoons golden syrup or light corn syrup
– 50g cocoa powder, sifted
– 100g dried fruit (raisins, cherries, or cranberries) – optional
– 50g chopped nuts (almonds or walnuts) – optional

Instructions:

Begin by lining a 20cm square baking tin with parchment paper, allowing excess to hang over the sides for easy removal. Break the digestive biscuits into a large mixing bowl, crushing them with your hands into various-sized pieces—aim for a mix of smaller crumbs and larger chunks about the size of a pound coin. This varied texture is what makes the Chocolate Biscuit Cake so appealing, creating interesting bite variations throughout.

In a medium saucepan over low heat, combine the butter and golden syrup, stirring until the butter melts completely. Break both chocolates into small pieces and add them to the pan, stirring continuously with a wooden spoon until you achieve a smooth, glossy mixture. Remove from heat and sift in the cocoa powder, whisking thoroughly to eliminate any lumps and create a silky ganache.

Pour the warm chocolate mixture over the crushed biscuits, adding dried fruit and nuts if using. Using a large spatula, fold everything together gently but thoroughly, ensuring every biscuit piece is coated with chocolate. The mixture will seem quite wet initially—this is perfect for a proper No bake biscuit cake.

Transfer the chocolate-coated mixture into your prepared tin, pressing down firmly with the back of a spoon or offset spatula to create an even, compact layer. Smooth the top surface as much as possible. Cover with plastic wrap and refrigerate for at least four hours, though overnight is ideal for the best slicing results.

Once fully set, lift the cake from the tin using the parchment paper overhang. Place on a cutting board and slice into 16 squares using a sharp knife, wiping the blade clean between cuts for neat edges.

Tips

For the cleanest slices, dip your knife in hot water and wipe dry between each cut. This prevents the chocolate from dragging and creating messy edges. Room temperature butter mixes more smoothly into the chocolate, preventing the mixture from seizing or becoming grainy. If you prefer a less sweet version, use entirely dark chocolate instead of the milk chocolate blend. Store the finished cake in an airtight container in the refrigerator for up to ten days, though it rarely lasts that long. Let slices sit at room temperature for about fifteen minutes before serving to achieve the perfect texture balance between firm chocolate and slightly softened biscuit. For a festive twist during holidays, add a tablespoon of rum or brandy to the chocolate mixture, or incorporate candied ginger for a spicy kick.

Alternative Methods

Vegan Version: Substitute butter with coconut oil or vegan butter, and use dairy-free chocolate. The texture remains remarkably similar with these plant-based swaps.

Gluten-Free Adaptation: Replace digestive biscuits with gluten-free graham crackers or rice cookies. The result maintains the same delightful crunch.

Individual Portions: Instead of a traybake, press the mixture into lined muffin tins to create individual servings perfect for lunch boxes or portion control.

Layered Variation: Divide the mixture in half, add white chocolate to one portion, and create alternating dark and white layers for visual appeal.

Cookie Variations: Experiment with different biscuit bases like ginger snaps for a spiced version, or vanilla wafers for a milder chocolate flavor profile.
