Ingredients
For the Cake Base
- 2 packets (800 grams) digestive biscuits (or Marie biscuits/Rich Tea biscuits)
- 1 cup (110 grams) pecans, lightly toasted and chopped (or nuts of choice)
- 1 cup (200 grams) white granulated sugar
- ½ cup (60 grams) unsweetened cocoa powder, sifted
- 1 cup (240 ml) whole milk
- ⅔ cup (150 grams) unsalted butter
- Pinch of salt
- 1 teaspoon pure vanilla extract
For the Chocolate Ganache
- ¾ cup (180 ml) heavy whipping cream (35% fat content)
- 1 cup (200 grams) semi-sweet chocolate chips
For Decoration
- ¼ cup pecans, lightly toasted and chopped
- 2 tablespoons semi-sweet chocolate chips
- Reserved chocolate ganache for drizzling
Detailed Instructions
Preparation Phase
- Break the biscuits into walnut-sized pieces in a large mixing bowl. Avoid making pieces too small — you want visible biscuit chunks in the final cake for texture and visual appeal. This is a perfect task to involve children in the kitchen!
- Toast the pecans in a preheated oven at 350°F (175°C) for 5 minutes until fragrant and lightly golden. Chop into small pieces and mix with the broken biscuits. Set the bowl aside while preparing the chocolate syrup.
Creating the Chocolate Syrup
- Combine dry ingredients in a heavy-bottomed saucepan: sugar, sifted cocoa powder, and salt. Whisk together to eliminate lumps and ensure even distribution.
- Add milk gradually while whisking continuously to create a smooth mixture without lumps. The consistency should be completely uniform before heating.
- Cook the chocolate base over medium heat, stirring constantly until the mixture begins to simmer and the sugar completely dissolves (about 3-4 minutes). You'll notice the mixture becoming more fluid as the sugar melts.
- Incorporate butter and continue cooking while whisking continuously. The mixture will gradually thicken over 7-8 minutes. You'll know it's ready when it coats the back of a spoon and has a glossy appearance.
- Finish with vanilla by removing from heat and stirring in the vanilla extract. Allow to cool for 1-2 minutes — the syrup should be warm but not scalding hot when added to biscuits.
Assembly Process
- Combine biscuits and chocolate syrup by pouring the warm chocolate mixture over the biscuit-nut combination. Using a large spoon or spatula, stir gently but thoroughly until every piece is well-coated with the chocolate syrup.
- Layer in springform pan by transferring half the mixture to a 9-inch springform pan. Spread evenly, ensuring the mixture reaches the edges, then press down gently to create a firm base layer.
- Complete the cake base by adding remaining biscuit mixture on top. Spread evenly and press down with a spatula to create a smooth, level surface. The gentle pressure helps the layers bind together properly.
- Initial chilling by covering with plastic wrap and refrigerating while preparing the ganache (about 30 minutes minimum).
Ganache Creation
- Heat the cream in a small heavy-bottomed saucepan over medium-low heat until it just begins to steam and small bubbles form around the edges. Do not allow to boil vigorously.
- Create the ganache by pouring hot cream over chocolate chips in a separate bowl. Let sit for 1 minute to allow heat to melt chocolate, then whisk from center outward until smooth and glossy.
- Top the cake by pouring most of the ganache over the chilled biscuit base, reserving about ¼ cup for decoration. Spread evenly with an offset spatula.
- Final setting by covering and refrigerating for 3-4 hours or overnight for best results. The longer chilling time allows flavors to meld and creates the perfect sliceable texture.
Serving and Decoration
- Unmold carefully by allowing the cake to sit at room temperature for 30 minutes before serving. Run a knife around the edges to release, then carefully remove the springform ring.
- Decorate beautifully by sprinkling chopped pecans and chocolate chips in the center, then drizzling reserved ganache over the top for an elegant finish.
Chef's Tips for Success
- Biscuit size matters: Break biscuits into walnut-sized pieces — too small and you lose texture, too large and the cake won't hold together properly
- Temperature control: Let the chocolate syrup cool slightly before adding to biscuits to prevent them from becoming soggy while ensuring proper coating
- Ganache consistency: If ganache becomes too thick, gently reheat with a tablespoon of cream; if too thin, let cool for 10 minutes before using
- Make-ahead advantage: This cake tastes even better after 24 hours as flavors develop and textures settle into perfect harmony
- Clean slicing technique: Use a sharp knife warmed in hot water and wiped clean between cuts for professional-looking slices
Nutritional Benefits
Compared to traditional baked chocolate cakes, this no-bake version offers several nutritional advantages. Pecans provide healthy fats for heart health and sustained energy. Dark chocolate delivers antioxidants that support cardiovascular function and cognitive health. Reduced refined ingredients compared to typical cake recipes means less processed sugar per serving. Higher protein content from nuts helps balance blood sugar response. No artificial preservatives since it's made fresh with whole ingredients you can pronounce.
Storage and Serving
Store covered in the refrigerator for up to 5 days, though it's best consumed within the first 3 days for optimal texture. Serve chilled or allow to come to room temperature for 15-20 minutes before serving for easier slicing. This cake makes an excellent make-ahead dessert for parties since the flavors actually improve with time, and you can prepare it up to 2 days in advance.

FAQ Section
A: Absolutely! Marie biscuits, Rich Tea biscuits, or even graham crackers work wonderfully. Choose biscuits with a sturdy texture that won't dissolve completely when mixed with the chocolate syrup.
A: If too thick, add milk one tablespoon at a time while still warm. If too thin, continue cooking for 2-3 more minutes until it properly coats a spoon. The consistency should be similar to warm chocolate sauce.
A: Yes! You can omit nuts entirely, substitute with mini marshmallows, dried fruit, or even crushed cookies for added texture and interest.
A: Perfect ganache should be smooth, glossy, and fall in ribbons from a whisk. If it looks grainy, the cream wasn't hot enough — gently reheat and whisk again.
A: Use any 9-inch round cake pan lined with parchment paper, leaving overhang for easy removal. You can also use an 8x8 square pan for a thicker cake.
A: Yes, wrap tightly and freeze for up to 2 months. Thaw overnight in refrigerator before serving. The texture may be slightly different but still delicious.
A: This usually happens when the chocolate syrup wasn't warm enough when mixed with biscuits, or the cake wasn't chilled long enough. Ensure 4+ hours of chilling time.
A: Try adding orange zest to the ganache, using different nuts, incorporating dried fruit, or even layering with different flavored biscuits for unique combinations.

Springform pan: A round cake pan with removable sides secured by a clamp, making it easy to unmold delicate cakes without turning upside down.
Steam point: The temperature just before boiling when small bubbles form around pan edges and steam rises from the surface — perfect for heating cream.
Tempering: In this context, allowing hot syrup to cool slightly before adding to biscuits prevents them from becoming too soggy while ensuring proper coating.
Coating consistency: When a mixture is thick enough to coat the back of a spoon and hold its shape briefly when drizzled.
Room temperature: Typically 68-72°F (20-22°C), the ideal temperature for ingredients to blend properly and for serving certain desserts.
Offset spatula: A narrow spatula with a bent blade that keeps your hand away from the surface, perfect for spreading ganache smoothly.
Bind: When ingredients stick together naturally, creating structure in the final product without additional binding agents.
Meld: The process of flavors combining and developing over time, which is why this cake improves when made ahead.
Ribbons: The way properly mixed ganache falls from a whisk in smooth, continuous streams rather than drops.
