Directions

For the Cake:

1. Preheat the oven to 350°F (175°C) and grease and flour an 8-inch round cake pan.

2. In a bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt.

3. In a large mixing bowl, beat the softened butter and sugar together until light and fluffy, about 3-5 minutes.

4. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

5. Gradually add the dry ingredients to the butter mixture, alternating with the buttermilk. Mix until just combined.

6. Pour the batter into the prepared cake pan and smooth the top. Bake for 25-30 minutes, or until a toothpick inserted comes out clean.

7. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

For the Raspberry Mousse:

1. In a blender or food processor, puree the raspberries with the sugar until smooth. Strain the puree through a fine mesh sieve to remove the seeds.

2. In a separate bowl, whip the heavy cream and vanilla extract until soft peaks form.

3. Gently fold in the melted dark chocolate and raspberry puree, mixing until well combined.

4. Refrigerate the mousse for about 30 minutes to set.

Assembling the Cake:

1. Once the cake has cooled completely, slice it in half horizontally to create two layers.

2. Place one layer on a serving plate and spread half of the raspberry mousse over it.

3. Add the second layer of cake and top with the remaining mousse.

4. Chill the assembled cake in the refrigerator for at least 1 hour.

For the Chocolate Ganache:

1. Heat the heavy cream in a small saucepan until just boiling.

2. Pour the hot cream over the chopped dark chocolate and let it sit for a few minutes.

3. Stir the mixture until smooth and glossy.

4. Drizzle the ganache over the chilled cake before serving.

Serving:

1. Garnish the top of the cake with fresh raspberries.

2. Slice and enjoy the luscious layers of cake, mousse, and ganache.

FAQs

1. Can I use frozen raspberries for the mousse?

Yes, frozen raspberries can be used. Just make sure to thaw and drain them before blending to remove excess moisture.

2. Can I make the cake ahead of time?

Yes, you can bake the cake a day ahead and store it at room temperature. Let it cool completely before assembling with the mousse and ganache.

3. How can I make the mousse lighter?

To make the mousse lighter, you can fold in whipped egg whites along with the whipped cream for a fluffier texture.

4. Can I use a different type of chocolate for the mousse and ganache?

Yes, you can use milk or semi-sweet chocolate, but dark chocolate creates the best balance with the tart raspberries.

5. How do I know when the cake is done baking?

The cake is done when a toothpick inserted into the center comes out clean or with just a few moist crumbs.

6. Can I skip the ganache?

While the ganache adds a rich finish, you can skip it if you prefer. The mousse and cake layers will still be delicious on their own.

7. Can I make this cake dairy-free?

You can substitute the cream cheese and heavy cream with dairy-free alternatives, though the texture and flavor may vary slightly.

8. How should I store leftover cake?

Leftovers should be stored in the refrigerator in an airtight container for up to 4 days to maintain freshness.

9. How can I make the mousse firmer?

If you prefer a firmer mousse, you can add a little gelatin or agar-agar (dissolved in warm water) to help it set more firmly.

10. Can I make this cake in a different pan size?

Yes, you can adjust the recipe for different pan sizes, but be sure to monitor the baking time as it may change based on the pan used.
