How to Make Chocolate Raspberry Mousse Cake

Chocolate Raspberry Mousse Cake – Easy Steps

1. Prepare the pans

Preheat your oven to 350°F (175°C).
Grease and flour three 9-inch round cake pans so the cakes don’t stick.

2. Make the chocolate cake batter

In a large bowl, whisk together:

• flour
• sugar
• cocoa powder
• baking soda
• salt

Add in the buttermilk, oil, egg, and vanilla.
Mix just until combined, then slowly stir in the hot water until the batter is smooth and thin.

3. Bake the cakes

Divide the batter evenly into 3 pans.
Bake for 20–25 minutes (layers are thinner, so they bake faster).
A toothpick should come out clean.
Let the cakes cool 10 min in the pans, then transfer to a rack to cool completely.

4. Make the raspberry mousse

Cook raspberries, sugar, and lemon juice in a saucepan for 5 minutes.
Strain out the seeds.
Sprinkle gelatin over the warm purée, let it sit 5 minutes, then heat again gently to dissolve.
Let cool to room temperature.
Whip cream to soft peaks, then fold in the raspberry mixture to make mousse.

5. Assemble the 3-layer cake

Place the first cake layer on a plate.
Spread a layer of raspberry mousse.
Add the second cake layer, spread mousse again.
Place the final cake layer on top.
Chill the whole cake at least 1 hour to set.

6. Make the chocolate glaze

Heat cream until it just begins to simmer.
Pour over chopped chocolate, let sit 2 min, then stir until smooth.
Add corn syrup for shine.

7. Glaze & decorate

Pour the warm glaze over the chilled cake, letting it drip down the sides.
Let it set.
Finish with fresh raspberries and powdered sugar.

Expert Tips for Perfect Chocolate Raspberry Mousse Cake

• Room Temperature Ingredients: Ensure all ingredients are at room temperature before you begin. This helps them combine more smoothly and evenly, resulting in a better texture for your cake and mousse.
• Gelatin Blooming: It’s crucial to let the gelatin bloom fully before heating. If not properly bloomed, it might not dissolve completely, leading to lumps in your mousse.
• Whipping Cream: Whip your cream to soft peaks for the mousse. Over-whipping can result in a grainy texture, while under-whipping won’t hold the mousse structure.
• Glaze Application: Make sure your cake is thoroughly chilled before glazing. This helps the glaze set quickly and evenly without sliding off.

Creative Variations and Substitutions

• White Chocolate Raspberry Mousse Cake: Substitute white chocolate for the semi-sweet chocolate in the glaze. This variation creates a sweeter, more delicate flavor profile that pairs beautifully with the tart raspberries.
• Nutty Chocolate Raspberry Cake: Add a layer of crushed toasted almonds or hazelnuts between the cake and mousse layers for a delightful crunch and nutty flavor that complements the chocolate and raspberry.
• Vegan Chocolate Raspberry Mousse Cake: Use a plant-based milk and oil in place of the buttermilk and heavy cream, and agar-agar instead of gelatin for a vegan-friendly version.

How to Store and Freeze Chocolate Raspberry Mousse Cake

• Room Temperature Storage: If you’re serving the cake the same day, it can be kept at room temperature for up to 4 hours. Cover it loosely with a cake dome to prevent drying out.
• Refrigerator Storage: Store the cake in the refrigerator if keeping it overnight or longer. Place it in an airtight container to maintain freshness for up to 4 days.
• Freezer Storage: To freeze, wrap the cake tightly in plastic wrap, then in aluminum foil. It can be frozen for up to 2 months. Thaw overnight in the refrigerator before serving.
• Reheating/Refreshing: While this cake is best served chilled, you can let it sit at room temperature for about 30 minutes before serving to soften slightly.
