Ingredients

Scale
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • ½ cup Dutch-processed cocoa powder
  • 1½ teaspoons baking powder
  • 1½ teaspoons baking soda
  • ½ teaspoon salt
  • ½ cup whole milk
  • 2 large eggs
  • ½ cup sour cream
  • ½ cup vegetable oil
  • 1 teaspoon vanilla extract
  • 1 teaspoon espresso powder
  • 1 cup hot water
  • 4 large egg yolks
  • 2 tablespoons granulated sugar
  • 2 tablespoons cornstarch
  • 1 teaspoon vanilla extract
  • 2 cups heavy cream, divided
  • 3.5 oz dark chocolate, chopped
  • 4.5 oz white chocolate, chopped
  • 5 oz milk chocolate, chopped
  • ⅓ cup heavy cream

Instructions

  1. Preheat oven to 350°F (180°C). In a bowl, combine dry ingredients: flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk eggs, milk, sour cream, vegetable oil, and vanilla until smooth. Combine wet and dry mixtures; stir in hot water until batter is silky.
  2. Divide batter into lined 8-inch round pans; bake for 35 minutes or until a toothpick comes out clean. Cool completely before leveling tops.
  3. For the mousse: heat one cup of heavy cream with vanilla until steaming. Whisk egg yolks with sugar and cornstarch; temper with hot cream. Cook until thickened; divide into two bowls. Stir in melted dark chocolate in one bowl and white chocolate in the other.
  4. Whip remaining cream; fold into each chocolate mixture to create mousses.
  5. Assemble by layering cake and mousse in a dessert ring. Chill until set.
  6. Make ganache by heating cream and pouring over chopped milk chocolate; stir until smooth. Cool slightly before pouring over the chilled cake.
