Instructions
Preheat oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.
Mix chocolate cookie crumbs with melted butter until evenly moistened. Press into the bottom of the prepared pan to form a crust. Bake for 8-10 minutes, then cool completely.
For each mousse layer, whip 1 cup heavy cream until soft peaks form in three separate bowls.
Combine melted dark chocolate with 1/4 cup powdered sugar, milk chocolate with 1/4 cup powdered sugar, and white chocolate with 1/4 cup powdered sugar in separate bowls.
Gently fold whipped cream into each chocolate mixture until smooth and fully combined.
Spread dark chocolate mousse over the cooled crust and chill briefly. Repeat with milk and white chocolate mousse layers, chilling briefly between layers.
For ganache, heat heavy cream until simmering, pour over chopped dark chocolate, let sit, then stir until glossy.
Drizzle ganache over the chilled cake before serving. Release from the springform pan, slice, and serve chilled.
Notes
Use high-quality chocolate for best flavor. Chill layers briefly to keep them distinct.
