Equipment

  • 9-Inch Springform Pan,
  • Electric mixer or stand mixer
  • Mixing bowls
  • Whisk
  • Spatula
  • Small saucepan
  • Fine mesh strainer (for raspberries)
  • Baking sheet (for the cake base)
  • Knife (for slicing)

Ingredients
  

For the Chocolate Cake Base:

  • 1 ½ cups all-purpose flour
  • 1 cup granulated sugar
  • ½ cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt
  • 2 large eggs room temperature
  • ½ cup whole milk
  • ½ cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water

For the Raspberry Mousse:

  • 1 ½ cups fresh raspberries or frozen, thawed
  • ½ cup powdered sugar
  • 1 tsp lemon juice
  • 1 cup heavy whipping cream
  • 8 oz semi-sweet chocolate chopped
  • 1 tbsp gelatin optional, for added structure

For the Chocolate Ganache Topping:

  • 1 cup heavy cream
  • 8 oz semi-sweet chocolate chopped

Instructions
 

Preheat and Prepare the Pan:

  • Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan with butter or cooking spray and line the bottom with parchment paper.

Make the Chocolate Cake:

  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. In a separate bowl, mix the eggs, milk, oil, and vanilla.
  • Gradually add the dry ingredients to the wet, then stir in the boiling water until smooth (the batter will be thin). Pour the batter into the prepared pan and bake for 30 minutes or until a toothpick comes out clean.
  • Let the cake cool in the pan for 10 minutes, then remove from the pan and cool completely on a wire rack.

Prepare the Raspberry Mousse:

  • Puree the raspberries in a blender and strain through a fine mesh sieve to remove the seeds. In a medium bowl, combine the raspberry puree, powdered sugar, and lemon juice.

Whip the Cream:

  • In a separate bowl, beat the heavy whipping cream until stiff peaks form. Fold the whipped cream gently into the raspberry mixture.

Melt the Chocolate:

  • Melt the semi-sweet chocolate in a microwave or double boiler until smooth. If using gelatin, dissolve it in a tablespoon of warm water, then stir it into the melted chocolate. Let the mixture cool slightly.

Combine the Mousse and Chocolate:

  • Fold the melted chocolate into the raspberry mousse mixture, ensuring it is fully incorporated and smooth. Refrigerate the mousse for 15-20 minutes to allow it to set.

Assemble the Cake:

  • Once the chocolate cake has cooled, slice it horizontally to create two even layers. Place one layer of cake at the bottom of a springform pan.

Layer the Mousse:

  • Spread a generous layer of raspberry mousse over the cake layer. Add the second layer of cake on top, gently pressing it down. Spread the remaining mousse over the top layer of cake. Refrigerate the assembled cake for at least 2 hours to allow the mousse to fully set.

Make the Ganache:

  • In a small saucepan, heat the heavy cream until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for a minute before stirring until smooth. Let the ganache cool slightly before pouring it over the mousse layer.

Chill and Serve:

  • Allow the ganache to set for 15-20 minutes at room temperature or refrigerate for a faster result. Once set, slice the cake into 10 even pieces and serve chilled with fresh raspberries for garnish.

Notes

 Cool the Cake Completely: Before assembling, make sure the chocolate cake layer is fully cooled to avoid melting the mousse. This helps maintain the cake’s structure and ensures a clean, neat finish.
 Chill Time: The mousse needs time to firm up, so be sure to chill the cake for at least 2 hours before serving. This will help the layers set properly and allow the flavors to meld together.
 Customization: Feel free to get creative with the decoration. Adding fresh berries, chocolate shavings, or a drizzle of raspberry sauce can elevate the presentation and add extra flavor.
