Instructions

  1. Prepare the Cake Base: Preheat oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan. In a large bowl, whisk together flour, sugar, cocoa, baking powder, baking soda, and salt. Add oil, eggs, vanilla, and buttermilk, mixing until combined. Stir in hot water until smooth. Pour into the pan and bake for 25–30 minutes or until a toothpick inserted comes out clean. Cool completely.
  2. Make the Dark Chocolate Mousse: Melt dark chocolate and butter in a heatproof bowl over simmering water, stirring until smooth. Let cool slightly. Whip cream and powdered sugar until soft peaks form. Fold in the cooled chocolate mixture gently. Spread evenly over the cooled cake base. Refrigerate for 30 minutes.
  3. Make the Milk Chocolate Mousse: Repeat the melting and whipping process using milk chocolate. Spread the mousse over the dark chocolate layer. Refrigerate for another 30 minutes.
  4. Make the White Chocolate Mousse: Repeat the melting and whipping process using white chocolate. Spread the mousse over the milk chocolate layer. Refrigerate for at least 4 hours, or overnight, for the cake to set fully.
  5. Release the cake from the springform pan, garnish as desired, slice, and serve chilled.
