Instructions
 

Base

  • Combine crushed cookies and melted butter. Press into the bottom of a springform pan to form a firm crust. Chill while preparing the mousse.

Dark Chocolate Mousse:

  • Melt dark chocolate and let cool slightly. Whip heavy cream and sugar until soft peaks form. (Optional: dissolve gelatin in warm water and stir into melted chocolate.) Fold whipped cream into the chocolate. Spread over the base and chill for 30 minutes.

Milk Chocolate Mousse:

  • Repeat the same steps with milk chocolate. Spread over the set dark chocolate layer and chill for another 30 minutes.

White Chocolate Mousse:

  • Prepare the white chocolate mousse following the same process. Gently spread over the milk chocolate layer.

Chill Completely:

  • Refrigerate the cake for at least 4 hours, or preferably overnight, to fully set.

Decorate and Serve:

  • Garnish with chocolate curls, cocoa powder, or fresh berries. Slice with a warm knife for clean layers and serve chilled.

Notes

For extra stability, especially in warm environments, gelatin is recommended.
Use high-quality chocolate bars for the best flavor and texture.
You can refrigerate the cake for up to 4 days or freeze it for up to 1 month.
