Ingredients

200g (7 oz) digestive biscuits or graham crackers, roughly broken
100g (3.5 oz) unsalted butter
200g (7 oz) dark chocolate (70% cocoa), roughly chopped
2 tablespoons golden syrup or honey
1 teaspoon vanilla extract
50g (1.75 oz) toasted almonds or hazelnuts, roughly chopped (optional)
50g (1.75 oz) dried cherries or raisins (optional)
A pinch of sea salt

Directions

To begin making this incredible No-Bake Chocolate Biscuit Cake, first line a 9×5 inch loaf pan with parchment paper, leaving some overhang for easy removal. In a large mixing bowl, break the biscuits into bite-sized pieces, ensuring you have a mix of larger chunks and smaller crumbs for the best texture.

Next, prepare the chocolate mixture. Melt the butter and dark chocolate together in a heatproof bowl set over a pan of simmering water, stirring occasionally until smooth and glossy. Be careful not to let the bowl touch the water. Once melted, remove from heat and stir in the golden syrup, vanilla extract, and a pinch of sea salt. Allow the mixture to cool for about 5 minutes so it is warm but not hot.

Pour the melted chocolate mixture over the broken biscuits. Using a rubber spatula, gently fold everything together until every piece of biscuit is completely coated. If you are using nuts or dried fruit, fold them in at this stage. The mixture should look glossy and well combined. Transfer the mixture into the prepared loaf pan, pressing it down firmly and evenly with the back of a spoon or a spatula. Smooth the top as much as possible. Refrigerate for at least 4 hours, or preferably overnight, until the cake is completely firm and set. Once set, lift the No-Bake Chocolate Biscuit Cake out of the pan using the parchment paper, slice it into thick pieces, and serve chilled or at room temperature.

Servings and Timing

This recipe yields 8 to 10 generous servings. The preparation time is about 15 minutes, and the chilling time is a minimum of 4 hours, though overnight is recommended for the best texture. The total time is approximately 4 hours and 15 minutes.

Variations

There are so many wonderful ways to customize this No-Bake Chocolate Biscuit Cake. For a richer flavor, you can substitute the dark chocolate with milk chocolate or use a combination of both. If you love a bit of crunch, try adding toasted coconut flakes or crushed pretzels to the biscuit mixture. For a festive twist, fold in some mini marshmallows and chopped candied ginger. You can also swap the golden syrup for maple syrup for a slightly different sweetness. For a truly decadent version, drizzle some melted white chocolate over the top before chilling.

Storage and Reheating

Store any leftover No-Bake Chocolate Biscuit Cake in an airtight container in the refrigerator for up to one week. This cake actually tastes even better the next day as the flavors meld together. To serve, you can enjoy it straight from the fridge for a firm, fudgy texture, or let it sit at room temperature for 10-15 minutes for a softer bite. This cake is not meant to be reheated, but if you prefer a softer texture, you can microwave a single slice for 10-15 seconds. For another great no-bake option, check out our No-Bake Chocolate Tart.

FAQs

Can I use a different type of biscuit?

Yes, absolutely! While digestive biscuits provide a classic flavor and texture, you can use graham crackers, shortbread cookies, or even rich tea biscuits. Just keep in mind that the texture will vary slightly. For a gluten-free version, use your favorite gluten-free biscuit.

Why is my No-Bake Chocolate Biscuit Cake too soft?

If your cake is too soft, it likely did not chill long enough. The chocolate and butter mixture needs at least 4 hours to set properly. If it is still soft after chilling, you may have used a chocolate with a lower cocoa butter content or added too much liquid sweetener. Ensure you are using good quality chocolate and pressing the mixture firmly into the pan.

Can I freeze this cake?

Yes, you can freeze this No-Bake Chocolate Biscuit Cake for up to 3 months. Wrap the entire cake or individual slices tightly in plastic wrap and then in aluminum foil. Thaw in the refrigerator overnight before serving. The texture remains excellent after freezing.

What is the origin of this dessert?

This dessert has roots in many cultures, with similar versions found in the UK, Australia, and parts of Europe. It is often called “Chocolate Biscuit Cake” or “Tiffin.” For more on the history of chocolate, you can read this Wikipedia article on chocolate.

Can I make this recipe vegan?

Yes, to make a vegan version, simply use a high-quality vegan dark chocolate and replace the butter with a plant-based butter or coconut oil. Use a vegan-friendly sweetener like maple syrup or agave nectar. The result will be just as delicious and decadent.
