Instructions
 

Preparation

  • Begin by preheating your oven to 350°F (175°C).
  • In a mixing bowl, combine the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. Whisk these dry ingredients together well.
  • In another bowl, cream the softened unsalted butter with granulated sugar until light and fluffy.
  • Add the eggs, one at a time, to the creamed mixture, mixing well after each addition.
  • Stir in the vanilla extract until well combined.
  • Next, alternate adding the dry ingredients and the buttermilk to the butter mixture, mixing until just combined.
  • Gently fold in the fresh raspberries.
  • Pour the batter into a greased 9-inch round cake pan and smooth the top.

Baking

  • Bake the cake until a toothpick inserted into the center comes out clean, about 25-30 minutes.
  • Allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.

Making the Mousse

  • In a bowl, combine the heavy cream with the 1/4 cup of granulated sugar and vanilla extract. Whip until soft peaks form.
  • Gently fold the melted dark chocolate into the whipped cream until well combined.

Assembling the Cake

  • Spread the mousse evenly over the cooled cake.
  • For the ganache, heat the heavy cream until hot but not boiling, then pour it over the chopped dark chocolate.
  • Stir until smooth and pour the ganache over the mousse layer.
  • Refrigerate the cake for at least 2 hours before serving.

Notes

Use room-temperature ingredients for best results. Don’t overmix the batter to avoid a dense cake. Allow cooling and refrigeration for proper texture.
