Ingredients
 

Main Ingredients

  • 2.5 cups all-purpose flour for the cake base
  • 1.5 cups granulated sugar
  • 1 cup unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 1.5 teaspoons baking soda
  • 1 teaspoon salt
  • 3 large eggs at room temperature
  • 1.5 cups whole milk
  • 0.75 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water for added moisture
  • 1 pound bittersweet chocolate chopped, for mousse
  • 2 cups heavy cream for mousse and ganache
  • 0.25 cup granulated sugar optional, if sweeter mousse is desired

Instructions

Preparation Steps

  • Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • In a large bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt. Add eggs, milk, oil, and vanilla. Mix until well combined, then stir in boiling water.
  • Pour batter evenly into the prepared pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Let cool completely.
  • For the mousse, melt the chocolate in a heatproof bowl over simmering water. Let it cool slightly.
  • Whip the heavy cream to stiff peaks in a separate bowl. Gently fold in melted chocolate until no streaks remain.
  • Layer the mousse between the cooled cakes. Refrigerate until set.
  • For the ganache, heat 1 cup of cream until just before boiling and pour over chopped chocolate. Stir until smooth.
  • Pour ganache over the cake and spread evenly. Let it set slightly before serving.

Notes

For the best flavor, make the cake the day before serving and refrigerate overnight.
