How to Make Triple Chocolate Mousse Cake

Prepare your genoise cake. If making from scratch, ensure it's completely cool before proceeding.
Make the chocolate mousse: In a medium heatproof bowl set over a pan of simmering water (double boiler), melt the bittersweet chocolate and 1/4 cup sugar, stirring occasionally until smooth. Remove from heat and stir in vanilla extract.
In a separate bowl, whip the 1 cup chilled heavy cream until soft peaks form. Gently fold the whipped cream into the melted chocolate until combined.
Make the chocolate ganache: In a double boiler, melt the semisweet and milk chocolate with the 1/2 cup heavy cream, stirring until smooth. Remove from heat, stir in the softened butter and powdered sugar until smooth and glossy.
Assemble the cake: Place one layer of genoise on a serving plate. Spread half of the chocolate mousse over the cake. Top with the second layer of genoise and spread the remaining mousse evenly.
Pour the chocolate ganache over the top of the mousse, allowing it to drip down the sides. Refrigerate for at least 4 hours, or preferably overnight, to allow the mousse to set completely.
Dust with cocoa powder before serving (optional).
