How to Make Triple Chocolate Mousse Cake

Ingredients

2 cups all-purpose flour
1/2 cup sifted cocoa powder, plus more for dusting
1 1/4 teaspoons baking soda
1/4 teaspoon baking powder
Pinch of salt
1 cup mayonnaise
1 cup granulated sugar
3 large eggs
1 1/4 cups water
1 teaspoon vanilla extract
8 ounces bittersweet chocolate, chopped
3/4 cup heavy cream
1 1/2 tablespoons corn syrup
1 1/2 teaspoons unflavored gelatin
1 tablespoon cold water
1 tablespoon boiling water
6 ounces bittersweet chocolate, chopped
1 1/2 cups heavy cream, divided
2 tablespoons granulated sugar

Directions

For the Cake: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch springform pan. In a large bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
In a separate bowl, beat together the mayonnaise, sugar, eggs, water, and vanilla extract. Pour the wet mixture into the dry ingredients and whisk until just combined.
Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan before frosting.
For the Ganache Frosting: Place the chopped chocolate in a heatproof bowl. In a small saucepan, heat the heavy cream and corn syrup until just simmering. Pour the hot cream mixture over the chocolate and let it sit for a minute. Stir until the chocolate melts and becomes smooth. Let the ganache cool slightly before frosting the cake.
For the Chocolate Mousse Filling: Sprinkle the gelatin over the cold water and let it bloom for 5 minutes. In another bowl, melt the chocolate in the microwave or over a double boiler. In a saucepan, heat the boiling water and add the bloomed gelatin, stirring until dissolved. Mix the gelatin with the melted chocolate until smooth.
In a clean bowl, beat 1 cup of heavy cream until stiff peaks form. Gently fold the whipped cream into the chocolate mixture until smooth.
To assemble the cake, place the cooled cake layer on a serving plate. Spread a layer of chocolate mousse on top and chill for 30 minutes. Repeat with another layer of cake and mousse. Frost the top and sides of the cake with the ganache frosting. Chill the cake for at least 4 hours before serving.
