Directions
Step 1 – Bake the base:
Preheat oven to 350°F (175°C). Prepare a 9-inch springform pan. Make a simple chocolate cake base by combining melted butter, sugar, cocoa powder, eggs, and flour. Bake for 20–25 minutes, then cool completely.

Step 3 – Make the milk chocolate mousse:
Repeat the same process using milk chocolate. Pour over the set dark chocolate layer and chill again for 45 minutes.
Step 4 – Make the white chocolate mousse:
Melt white chocolate and repeat the process, folding into whipped cream and gelatin. Spread over the milk chocolate layer. Refrigerate for at least 4 hours or overnight to set completely.
Step 5 – Finish and serve:
Before serving, carefully remove the cake from the springform pan. Smooth the edges with a warm knife and top with chocolate shavings, cocoa powder, or curls for an elegant finish.
