Ingredients

Scale
  • 1 cup (125g) all-purpose flour
  • 1/2 cup (50g) unsweetened cocoa powder
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 3/4 cup (150g) granulated sugar
  • 2 large eggs, room temperature
  • 1/2 cup (120ml) milk
  • 1/4 cup (60ml) vegetable oil
  • 1 teaspoon vanilla extract
  • 1/2 cup (120ml) boiling water
  • 6 ounces (170g) semi-sweet chocolate, chopped
  • 2 cups (480ml) heavy cream, divided
  • 1/4 cup (30g) powdered sugar
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat the oven to 350Β°F (175Β°C). Grease and line a 9-inch round cake pan with parchment paper.
  2. In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
  3. In another bowl, whisk together the sugar, eggs, milk, vegetable oil, and vanilla extract until smooth.
  4. Gradually add the dry mixture to the wet ingredients, stirring until just combined.
  5. Slowly pour in the boiling water, mixing until the batter is smooth. The batter will be thin.
  6. Pour the batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely on a wire rack.
  7. Melt the chopped chocolate over a double boiler or in the microwave (30-second intervals, stirring in between). Let it cool slightly.
  8. In a large bowl, beat 1 1/2 cups (360ml) of heavy cream with powdered sugar and vanilla extract until stiff peaks form.
  9. Gently fold the cooled chocolate into the whipped cream until fully combined.
  10. Spread the mousse evenly over the cooled cake. Smooth the top with a spatula.
  11. Refrigerate the cake for at least 1 hour before serving to allow the mousse to set.

Notes

Use room temperature eggs for a smoother batter. Sift dry ingredients to prevent lumps. Chill thoroughly for the perfect mousse texture. Add a sprinkle of sea salt on top for a sweet-and-salty combination.
