How to Make It
Follow these simple steps to create your cake:
Preheat the Oven
Preheat the oven to 350°F (175°C) and grease and flour an 8-inch round cake pan.
Whisk Dry Ingredients
In a bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and sugar until light and fluffy, about 3-5 minutes.
Add Eggs and Vanilla
Add eggs one at a time, mixing well after each addition, then stir in vanilla extract.
Combine Mixtures
Gradually add the dry ingredients to the butter mixture, alternating with buttermilk, mixing until just combined.
Bake the Cake
Pour the batter into the prepared cake pan and smooth the top. Bake for 25-30 minutes, or until a toothpick comes out clean.
Cool the Cake
Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Prepare Raspberry Mousse
For the raspberry mousse, puree raspberries with sugar in a blender, then strain through a fine mesh sieve.
Whip Cream
Whip heavy cream and vanilla extract until soft peaks form, then fold in melted dark chocolate and raspberry puree.
Chill Mousse
Refrigerate the mousse for about 30 minutes to set.
Layer the Cake
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, then add the second layer and top with remaining mousse.
Chill Assembled Cake
Chill the assembled cake in the refrigerator for at least 1 hour.
Make the Ganache
For the ganache, heat heavy cream until just boiling, then pour over chopped dark chocolate and let sit for a few minutes before stirring until smooth.
Drizzle Ganache
Drizzle the ganache over the chilled cake before serving.
How to Store It
Fridge: store in an airtight container for up to 3 days.
Freezer: no, cake texture may change.
Reheat: none needed, serve cold or at room temperature.
Tips for Best Results
