Method
 

Bake Cake
  1. In a mixing bowl, combine all the dry ingredients: flour, cocoa powder, baking powder, baking soda, and sugar.
  2. Add the wet ingredients—milk, melted butter, eggs, and vanilla extract—mixing until just combined.
  3. Pour the batter into a greased cake pan and bake at 350°F (175°C) for 20-25 minutes, or until a toothpick inserted in the center comes out clean.
  4. Let the cake cool completely.
Make Mousse
  1. In a blender, combine the fresh raspberries, sugar, and lemon juice, blending until smooth.
  2. Strain the mixture to remove seeds and set aside.
  3. In a small bowl, dissolve the gelatin in water and heat gently until fully dissolved.
  4. Mix this into the raspberry puree.
  5. In another bowl, whip the heavy cream until soft peaks form, then gently fold it into the raspberry mixture until well incorporated.
Assemble
  1. Once the cake has cooled, spread the raspberry mousse evenly over the top of the cake, smoothing it out.
  2. Cover with plastic wrap or foil and chill in the refrigerator for at least 2 hours to set the mousse.
Top with Ganache
  1. After the mousse has set, prepare the ganache by heating the heavy cream in a small saucepan until it just begins to simmer.
  2. Remove from heat and pour it over the dark chocolate chips in a bowl.
  3. Stir until the chocolate is melted and the mixture is smooth.
  4. Pour the ganache over the mousse layer, spreading it evenly.
Chill & Serve
  1. Refrigerate the assembled cake for an additional hour to allow the ganache to set.
  2. Once chilled, carefully slice the cake into pieces and serve to family and friends.

Notes

Use high-quality chocolate chips for a rich, velvety ganache. Garnish with fresh raspberries or cocoa powder. Chill heavy cream for optimal whipping.
