Step-by-Step Instructions

Step 1: Prepare the Biscuits

Break the biscuits into bite-sized pieces. Avoid crushing them into crumbs; larger chunks create the signature mosaic pattern.

Place them in a large mixing bowl.

Step 2: Make the Chocolate Mixture

In a saucepan over low heat, combine the butter, heavy cream, sugar, cocoa powder, and salt. Stir until the butter melts and the sugar dissolves.

Remove from the heat and add the chopped dark and milk chocolate. Let sit for one minute, then stir until smooth and glossy.

Mix in the vanilla extract.

Step 3: Combine Everything

Pour the warm chocolate mixture over the broken biscuits.

Add any optional mix-ins such as nuts, marshmallows, dried fruit, or coconut.

Gently fold until every biscuit piece is evenly coated.

Step 4: Fill the Pan

Line your cake pan with parchment paper.

Transfer the mixture into the pan and press it down firmly with the back of a spoon or spatula to remove air pockets and create an even surface.

Step 5: Chill

Refrigerate the cake for at least 4–6 hours, or overnight, until completely firm.

Step 6: Make the Ganache

Heat the heavy cream until just simmering.

Pour it over the chopped chocolate.

Let stand for one minute, then stir until smooth.

Add the butter and stir until glossy.

Allow the ganache to cool slightly before pouring it over the chilled cake.

Return the cake to the refrigerator for another 30 minutes.

Step 7: Decorate and Serve

Remove the cake from the pan.

Decorate with chocolate shavings, crushed biscuits, cocoa powder, chopped pistachios, or fresh berries.

Slice with a warm knife for clean, neat pieces.
