Dark Chocolate Raspberry Mousse Cake

Why You’ll Love This Dark Chocolate Raspberry Mousse Cake

This dark chocolate raspberry mousse cake layers a tender cocoa cake with raspberry-dark chocolate mousse and a dark chocolate ganache drizzle. Fresh raspberries add a bright, tart note to balance the chocolate. Chill the assembled cake before serving so the mousse can firm up and the slices hold their shape.

How the Chocolate and Raspberry Layers Work

The cake is baked in an 8-inch pan, cooled, and split horizontally. Raspberry puree is folded into whipped cream and melted chocolate to make the mousse, which fills and tops the layers. A final chill sets the cake before the ganache goes on. For another berry-and-chocolate celebration cake, see this pistachio raspberry cake.

Directions

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 flour, cocoa powder, baking powder, baking soda, and salt.
3. In a large mixing bowl, beat the softened butter and sugar until light and fluffy, about 3-5 minutes.
4. Add eggs one at a time, mixing well after each addition, then stir in vanilla extract.
5. Gradually add the dry ingredients to the butter mixture, alternating with buttermilk, mixing 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 comes out clean.
7. Allow the cake to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
8. For the raspberry mousse, puree raspberries with sugar in a blender, then strain through a fine mesh sieve.
9. Whip heavy cream and vanilla extract until soft peaks form, then fold in melted dark chocolate and raspberry puree.
10. Refrigerate the mousse for about 30 minutes to set.
11. Once the cake is cooled, slice it in half horizontally to create two layers.
12. 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.
13. Chill the assembled cake in the refrigerator for at least 1 hour.
14. 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.
15. Drizzle the ganache over the chilled cake before serving.

How to Serve Dark Chocolate Raspberry Mousse Cake

Keep the cake chilled until just before serving, then cut it into wedges with a warm, clean knife for neater slices. Garnish with fresh raspberries or whipped cream and serve with coffee or tea.

How to Store Dark Chocolate Raspberry Mousse Cake

Cover leftover cake and refrigerate it for up to 3 days. Keep it chilled between servings so the mousse stays firm.

Tips for Dark Chocolate Raspberry Mousse Cake

• Let the butter soften before creaming it with the sugar so the cake batter mixes evenly.
• Choose a dark chocolate you enjoy eating; its flavor will carry through both the mousse and ganache.
• Line the bottom of the pan with parchment and grease the sides to help release the cooled cake.
• If you like a stronger raspberry flavor, feel free to add more raspberries to the mousse.

Variations

You can replace the raspberries with other berries like strawberries, blackberries, or blueberries for a different twist. You could also add a layer of whipped cream between the cake layers for added creaminess.

Frequently Asked Questions

Can I make this cake ahead?
You can bake the cake layer a day ahead and refrigerate it once fully cooled. Prepare and add the mousse closer to serving, then chill the assembled cake until set.

Can I use milk chocolate instead of dark?
Yes. It will make the mousse and ganache sweeter, so taste the mixture before adding any extra sugar.

What if the mousse seems too soft?
Chill it longer before assembling. Whip the cream to soft peaks as directed; overwhipping can make it grainy.
