Instructions
Make the Cake Base: Mix flour, cocoa powder, sugar, butter, and eggs. Pour into a greased springform pan and bake at 350°F (175°C) for 25–30 minutes. Let cool.
Prepare the Mousse: Melt semi-sweet, milk, and white chocolate separately. Whip 1/3 cup heavy cream and fold into each melted chocolate.
Layer the Cake: Spread semi-sweet chocolate mousse over the cooled cake base and chill. Repeat with milk chocolate and white chocolate mousse layers.
Finish: Chill the assembled cake for 2 hours, then top with whipped cream and chocolate shavings before serving.
Notes
For best results, allow each mousse layer to firm up before adding the next.
Make this cake a day in advance for a more intense flavor.
