Description

A luxurious dessert combining rich chocolate cake, airy mousse, and silky ganache, perfect for any special occasion.


Ingredients

  • 1 cup all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1/2 cup vegetable oil
  • 1/2 cup buttermilk
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/2 cup boiling water
  • 2 cups heavy cream
  • 8 ounces semisweet chocolate, chopped
  • 1/4 cup granulated sugar (for mousse)
  • 1 teaspoon vanilla extract (for mousse)
  • 1 cup heavy cream (for ganache)
  • 8 ounces semisweet chocolate, chopped (for ganache)


Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large bowl, combine flour, sugar, cocoa powder, baking soda, baking powder, and salt. Whisk and set aside.
  3. In another bowl, whisk together vegetable oil, buttermilk, eggs, and vanilla extract until smooth. Gradually add to the dry mixture and mix until just combined.
  4. Slowly add boiling water, stirring gently until smooth.
  5. Divide batter between prepared pans. Bake for 25-30 minutes until a toothpick comes out clean. Cool in pans for 10 minutes before transferring to a wire rack.
  6. For the mousse, heat 1/2 cup of heavy cream until steaming. Pour over chopped chocolate, let sit for 5 minutes, then whisk until smooth.
  7. Whip remaining cream with sugar and vanilla until soft peaks form. Fold in chocolate mixture until well combined. Refrigerate for at least 1 hour.
  8. For the ganache, heat heavy cream until it simmers. Pour over chopped chocolate, let sit, then stir until smooth.
  9. Once cakes are cool, place one layer on a serving plate. Spread with chocolate mousse, add second layer, and cover with remaining mousse.
  10. Pour ganache over the cake, allowing it to drip down the sides. Chill for at least 2 hours before serving.

Notes

Use high-quality chocolate for the best flavor. Chill bowls and whisk before whipping cream for sturdier peaks.
