Step-by-step instructions
Follow these easy steps to assemble a glossy, layered chocolate biscuit cake that sets beautifully.
Step 1: Line the mold
Place a square metal frame or cake ring on parchment paper. Arrange a single layer of whole square biscuits to cover the base completely.
Step 2: Crush remaining biscuits
Take about half the remaining biscuits and break them into irregular pieces by hand. Keep some larger chunks for texture inside the filling.
Step 3: Melt the chocolate
Combine dark chocolate with milk or cream in a heatproof bowl. Melt gently until smooth and pourable, stirring in butter if using for extra shine.
Step 4: Mix the filling
Pour most of the melted chocolate over the crushed biscuits. Stir until every piece is fully coated and the mixture becomes thick and sticky.
Step 5: Spread the filling
Spoon the chocolate-biscuit mixture over the base layer of whole biscuits. Press it down evenly with a spatula to form a compact middle layer.
Step 6: Add top biscuit layer
Arrange another neat layer of whole square biscuits over the chocolate filling. Press gently so they adhere without sinking.
Step 7: Pour the glaze
Pour the remaining melted chocolate over the top biscuit layer. Spread it smoothly to create a glossy, even coating that covers every edge.

Step 8: Chill and slice
Refrigerate the cake for at least two hours until fully set. Remove the frame, cut into neat squares, and serve.
