How To Make Chocolate Raspberry Mousse Cake

1. Make the Moist Chocolate Cake:

1. Preheat oven to 350°F (175°C). Grease and line two 8 or 9-inch round cake pans. In a large bowl, whisk flour, sugar, cocoa powder, baking powder, baking soda, and salt.

2. In another bowl, beat eggs, egg white, buttermilk, oil, and vanilla. Gradually mix the wet ingredients into the dry, then slowly add the boiling water.

3. Pour batter evenly into prepared pans and bake for 30–35 minutes. Cool completely.

2. Prepare Chocolate Mousse:

1. In a saucepan, combine cocoa powder, sugar, and salt. Stir in milk over medium heat until smooth. Add chocolate chips and stir until melted. Remove from heat, stir in vanilla and warm water.

2. Cool to room temperature. In a separate bowl, whip heavy cream to stiff peaks. Gently fold in the chocolate mixture. Chill in refrigerator until ready to assemble.

3. Make Raspberry Mousse:

1. Puree raspberries and strain to remove seeds. In a small bowl, combine gelatin and water; let bloom for 5 minutes.

2. Heat white chocolate until melted, stir in raspberry puree and gelatin until fully dissolved. Allow to cool slightly, then fold into whipped cream. Chill until firm enough to spread.

4. Prepare Chocolate Buttercream Frosting:

1. Beat butter until creamy. Add powdered sugar, sifted cocoa, and salt; mix until fluffy. Pour in melted chocolate, vanilla, and cream; beat until smooth and spreadable.

5. Assemble the Cake:

1. Level the cake layers if needed. Place one cake layer on a serving plate. Spread a layer of raspberry mousse, then a layer of chocolate mousse.

2. Add the second cake layer and repeat mousse layers if desired. Frost the entire cake with chocolate buttercream. Chill for at least 4 hours before serving for clean slices.

Notes

❖ Cool the Cake Completely: Before assembling, make sure the chocolate cake layer is fully cooled to avoid melting the mousse. This helps maintain the cake’s structure and ensures a clean, neat finish.

❖ Chill Time: The mousse needs time to firm up, so be sure to chill the cake for at least 2 hours before serving. This will help the layers set properly and allow the flavors to meld together.

❖ Customization: Feel free to get creative with the decoration. Adding fresh berries, chocolate shavings, or a drizzle of raspberry sauce can elevate the presentation and add extra flavor.

Decorate Your Chocolate Raspberry Mousse Cake

1. Fresh Berries & Mint

Top the cake with a vibrant assortment of fresh raspberries, blackberries, or strawberries. Add a few sprigs of fresh mint for a pop of color and a refreshing contrast to the rich chocolate.

2. Chocolate Shavings or Curls

For a luxurious touch, use a vegetable peeler or grater to create delicate chocolate shavings or curls. Scatter them across the top of the cake for an elegant, chocolatey finish.

3. Whipped Cream Rosettes

Pipe beautiful rosettes of freshly whipped cream along the edges of the cake or in a decorative pattern on top. It’s simple but adds a touch of sophistication.

4. Drizzle of Raspberry Sauce

Make a homemade raspberry coulis or sauce by pureeing raspberries with a little sugar, then strain it for smoothness. Drizzle it artfully over the cake for a burst of color and flavor.

5. Edible Gold Dust

For a truly decadent look, lightly dust the cake with edible gold leaf or gold powder. It adds a touch of glamour and makes the cake feel extra special.

Substitutions For Your Chocolate Raspberry Mousse Cake

1. Flour: For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend or almond flour. This will keep the cake moist while catering to those with dietary restrictions.

2. Sugar: To reduce sugar, use a natural sweetener like stevia or erythritol in place of granulated sugar. For a more refined alternative, try coconut sugar for a deeper flavor.

3. Heavy Cream: If you’re looking for a lighter option, substitute heavy cream with coconut cream. It’ll still provide the richness needed for the mousse while adding a hint of coconut flavor.

4. Gelatin: If you prefer to avoid gelatin, you can use agar-agar as a vegetarian alternative. Simply follow the instructions on the package to achieve a similar mousse texture.

5. Chocolate: Swap out semisweet chocolate for dark chocolate (70% cocoa or higher) for a more intense chocolate flavor, or use milk chocolate for a sweeter, creamier finish.

How To Store

To store the finished Chocolate Raspberry Mousse Cake, cover it loosely with plastic wrap or place it in an airtight container to prevent it from absorbing odors in the fridge.

Keep it refrigerated for up to 3–4 days. If you need to store it for longer, consider freezing individual slices.

To freeze, wrap slices tightly in plastic wrap and foil, then store in a freezer-safe container for up to 1–2 months. Thaw in the fridge before serving for the best texture and flavor.
