How to Make Raspberry Chocolate Mousse Cake

Bake the Chocolate Cake

1. Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. In a large bowl, whisk together flour, sugar, cocoa powder, baking powder, baking soda, and salt.
3. Add eggs, milk, vegetable oil, and vanilla extract. Beat on medium speed for 2 minutes.
4. Stir in boiling water (batter will be thin). Pour evenly into prepared pans.
5. Bake for 30–35 minutes, until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.

Prepare the Raspberry Mousse

6. Puree fresh raspberries in a blender or food processor. Strain through a fine mesh to remove seeds if desired.
7. In a mixing bowl, whip heavy cream, powdered sugar, and vanilla extract to soft peaks.
8. Gently fold the raspberry puree into the whipped cream. If using gelatin, dissolve it in a small amount of warm water and fold it in at this stage.

Make the Chocolate Ganache

9. Heat heavy cream in a small saucepan until it begins to simmer.
10. Remove from heat, add chocolate chips, and let sit for 5 minutes. Stir until smooth and glossy.

Assemble the Cake

11. Place one cake layer on a serving plate. Spread a layer of raspberry mousse evenly on top.
12. Add the second cake layer and gently press down. Spread the remaining mousse over the top and sides.
13. Pour the chocolate ganache over the top, letting it drip down the sides.
14. Decorate with fresh raspberries and dark chocolate shavings.
15. Chill in the refrigerator for at least 2 hours to allow the mousse to set before slicing.

Tips for Success

• Use high-quality cocoa powder and chocolate for the best flavor.
• Strain raspberry puree to remove seeds for a smooth mousse.
• Chill the cake long enough for mousse and ganache to set completely.
• Fold the whipped cream gently into the raspberry puree to maintain lightness.
• For firmer mousse, use gelatin as instructed.
