Ingredients You’ll Need
For this luxurious no-bake chocolate biscuit cake, quality ingredients make all the difference. Here’s everything you’ll need to serve 10-12 people:
For the Cake Base:
- 400g digestive biscuits (can substitute graham crackers or rich tea biscuits)
- 225g unsalted butter
- 225g dark chocolate (70% cocoa solids)
- 100g granulated sugar
- 3 tablespoons golden syrup (or honey)
- 3 tablespoons unsweetened cocoa powder
- 1 teaspoon vanilla extract
- Pinch of salt
For the Chocolate Ganache:
- 200g dark chocolate (70% cocoa solids)
- 200ml heavy cream
- 25g unsalted butter
Optional Mix-ins (choose 1-2):
- 100g dried cherries
- 100g chopped toasted nuts (walnuts, hazelnuts, or pistachios work beautifully)
- 100g mini marshmallows
- 2 tablespoons orange zest
- 100g crystallized ginger, finely chopped
Equipment Needed
One of the joys of this recipe is how little equipment you need:
- 8-inch springform pan or loaf tin
- Parchment paper
- Large mixing bowl
- Medium saucepan
- Spatula
- Food processor or rolling pin and ziplock bag (for crushing biscuits)
- Measuring cups and spoons
- Refrigerator (of course!)
Step-by-Step Instructions
Preparing the Biscuit Base
- Prepare your pan: Line an 8-inch springform pan with parchment paper, ensuring the paper comes up the sides a bit.
- Crush the biscuits: Place the digestive biscuits in a food processor and pulse until you have a mixture of fine crumbs and small chunks (about the size of peas). If you don’t have a food processor, place the biscuits in a sealed plastic bag and crush them with a rolling pin. The texture variation makes for a more interesting final cake.
- Create the chocolate mixture: In a medium saucepan over low heat, combine the butter, chocolate, sugar, golden syrup, cocoa powder, and salt. Stir continuously until everything is melted and well combined. Remove from heat and stir in the vanilla extract.
- Combine with biscuits: Pour the warm chocolate mixture over the crushed biscuits and stir until all the biscuit pieces are thoroughly coated. If you’re using any of the optional mix-ins, fold them in now.
- Transfer to pan: Spoon the mixture into your prepared pan, pressing down firmly with the back of a spoon to eliminate air pockets. Pay special attention to the edges and corners.
- Initial chill: Place the pan in the refrigerator while you prepare the ganache. This helps set the base slightly.
Making the Chocolate Ganache
- Prepare the chocolate: Finely chop the dark chocolate and place it in a heatproof bowl.
- Heat the cream: In a small saucepan, bring the heavy cream just to a simmer. Watch it carefully as cream can boil over quickly.
- Create the ganache: Pour the hot cream over the chopped chocolate and let it sit for 2 minutes. Then, stir gently until the chocolate is completely melted and the mixture is smooth and glossy.
- Add the butter: While the ganache is still warm, add the butter and stir until incorporated. This gives the ganache a beautiful shine.
Finishing the Cake
- Add the ganache: Remove the cake from the refrigerator and pour the ganache over the top, using a spatula to spread it evenly and ensure it drips down the sides if you’re using a loaf tin.
- Final chill: Return the cake to the refrigerator and let it set for at least 4 hours, but preferably overnight. This waiting period allows the biscuits to soften slightly and the flavors to meld together.
- Serve: To serve, remove the cake from the springform pan and carefully peel away the parchment paper. If you used a loaf tin, you can use the overhanging parchment to lift the cake out before slicing.
Tips for Perfection
To ensure your chocolate biscuit cake turns out perfectly every time, keep these tips in mind:
- Quality matters: Use the best quality chocolate you can afford. Since chocolate is the star ingredient, its flavor will significantly impact the final result.
- Temperature control: When melting chocolate, always use low heat and stir constantly to prevent burning.
- Texture balance: The ideal texture includes both fine crumbs and small biscuit pieces for an interesting mouthfeel.
- Chilling time: Don’t rush the chilling process. The longer the cake sits, the better it tastes as the flavors meld and the biscuits soften to the perfect consistency.
- Slicing tip: For clean slices, dip your knife in hot water and wipe it dry between cuts.

Frequently Asked Questions
Can I use milk chocolate instead of dark chocolate? Yes, you can substitute milk chocolate, but the cake will be considerably sweeter. I’d recommend reducing the sugar by half if you go this route.
My cake seems too crumbly. What went wrong? The most likely cause is that there wasn’t enough “glue” (the chocolate mixture) to hold the biscuit pieces together. Make sure you have the right proportion of biscuits to chocolate mixture, and press the mixture very firmly into the pan.
Can I make this cake gluten-free? Absolutely! Simply use your favorite gluten-free biscuits or cookies in place of the digestive biscuits.
What can I substitute for golden syrup? Honey, maple syrup, or corn syrup will all work as substitutes, though each will bring a slightly different flavor profile to the cake.
How do I know when the cake is properly set? The cake should feel firm to the touch and the ganache should not be tacky when gently pressed with a finger.
Can I add alcohol to this recipe? Yes! Add 2-3 tablespoons of your favorite liqueur (think Baileys, Kahlúa, or Grand Marnier) to the chocolate mixture for an adult version.
My ganache separated or looks grainy. Can I fix it? If your ganache separates, you can usually rescue it by whisking in a little warm cream. If it’s grainy, it may have overheated – try gently warming it over a double boiler while whisking vigorously.
Is this cake suitable for vegetarians? Yes, this recipe is vegetarian. To make it vegan, use plant-based butter and ensure your chocolate doesn’t contain milk solids.
My Personal Touch
What I love most about this recipe is its versatility and reliability. I’ve made it countless times for various occasions – from casual family gatherings to more formal dinner parties – and it never fails to impress.
My favorite variation includes adding a handful of dried cherries and a splash of kirsch to the biscuit mixture, then finishing the cake with a sprinkle of chopped pistachios on top of the ganache for a festive red and green touch. The slight tartness of the cherries perfectly balances the richness of the chocolate.
For those special occasions when I really want to wow my guests, I sometimes make a double batch and create a layer cake, with a thin layer of raspberry jam between the layers and fresh raspberries on top. The combination of the dense, rich chocolate cake with the bright berry flavors is simply divine.
Whether you stick to the classic recipe or experiment with your own variations, this no-bake chocolate biscuit cake is sure to become a staple in your dessert repertoire. It’s the perfect balance of sophistication and comfort, requiring minimal effort but delivering maximum enjoyment. Happy no-baking!
