  • 1/2 cup Unsweetened cocoa powder
  • 1 teaspoon Baking powder
  • 1/2 teaspoon Baking soda
  • 1/4 teaspoon Salt
  • 1/2 cup Unsalted butter
  • 1 cup Granulated sugar
  • 2 large Eggs
  • 1 teaspoon Vanilla extract
  • 1/2 cup Buttermilk

For the Raspberry Mousse

  • 1/4 cup Granulated sugar
  • 1 cup Heavy cream
  • 1 teaspoon Vanilla extract

For the Ganache

  • 4 ounces Dark chocolate
  • 1/2 cup Heavy cream

Instructions
 

Preparation

  • Preheat the oven to 350°F (175°C) and grease and flour an 8-inch round cake pan.
  • In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
  • In a large mixing bowl, beat the softened butter and sugar until light and fluffy, about 3-5 minutes.
  • Add eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  • Gradually add the dry ingredients to the butter mixture, alternating with buttermilk, mixing until just combined.
  • Pour the batter into the prepared cake pan and smooth the top.

Baking

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

Raspberry Mousse Preparation

  • Puree raspberries with sugar in a blender, then strain through a fine mesh sieve.
  • Whip heavy cream and vanilla extract until soft peaks form, then fold in melted dark chocolate and raspberry puree.
  • Refrigerate the mousse for about 30 minutes to set.

Assembly

  • Once the cake is cooled, slice it in half horizontally to create two layers.
  • Place one layer on a serving plate and spread half of the raspberry mousse over it.
  • Add the second layer and top with remaining mousse.
  • Chill the assembled cake in the refrigerator for at least 1 hour.

Ganache Preparation

  • Heat heavy cream until just boiling, then pour over chopped dark chocolate and let sit for a few minutes before stirring until smooth.
  • Drizzle the ganache over the chilled cake before serving.

Notes

Serve with fresh raspberries and a dusting of powdered sugar on top. Cake can be stored in an airtight container for up to four days.
