Instructions
Step 1: Preheat and Prepare Pans
Preheat your oven to 350°F (175°C). Grease two 9-inches round cake pans and line the bottoms with parchment paper. Lightly flour the sides.
Step 2: Mix Dry Ingredients for Cake
In a medium bowl, sift together flour, cocoa powder, baking powder, baking soda, salt, and instant espresso. Set aside.
Step 3: Combine Wet Ingredients
In a large bowl, whisk together sugar, eggs, sour cream, oil, vanilla, and warm water until smooth.
Step 4: Incorporate Dry and Wet
Gradually add the dry ingredients into the wet mixture. Fold gently with a spatula until fully combined and smooth. Avoid over mixing.
Step 5: Bake the Cake
Divide the batter evenly between the two prepared pans. Bake for 35–40 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely on wire racks.
Step 6: Make Raspberry Filling
In a small saucepan, combine raspberries, sugar, cornstarch, lemon juice, and water. Cook over medium heat, stirring constantly until the mixture thickens. Remove from heat and let it cool completely.
Step 7: Prepare Chocolate Mousse

Step 8: Assemble Cake Layers
Place one cooled cake layer on your serving plate. Spread the cooled raspberry filling evenly over the layer.
Step 9: Add Mousse
Spoon the chocolate mousse on top of the raspberry layer and smooth it with an offset spatula. Carefully place the second cake layer on top.
Step 10: Make Chocolate Buttercream
In a mixing bowl, beat butter until creamy. Add sifted cocoa powder, powdered sugar, salt, melted chocolate, vanilla, and cream. Beat until smooth and fluffy.
Step 11: Frost the Cake
Spread the chocolate buttercream evenly over the top and sides of the cake. Use a spatula or a cake scraper to smooth edges. Decorate as desired with extra raspberries or chocolate shavings.
Step 12: Chill and Serve
Chill the cake in the refrigerator for at least 2 hours before slicing. This allows the mousse and filling to set perfectly. Slice with a warm knife for clean edges.

Why You’ll Love This Recipe
This chocolate raspberry mousse cake recipe is a dessert that truly delights. The chocolate cake layers are soft and moist, providing a rich base for the fresh, tangy raspberry filling.
The chocolate mousse adds a creamy, airy texture that balances the sweetness and fruitiness of the raspberries. Making it allows for personal touches, like adjusting chocolate intensity or layering style, which makes the process enjoyable and creative.
The cake not only tastes indulgent but also looks impressive when served, making it rewarding to share with friends or family after hours of careful preparation.
Why My Recipe Works
This chocolate raspberry mousse cake recipe works because the textures and flavors are carefully balanced. The chocolate cake layers stay moist thanks to the sour cream and warm water, while the baking powder and soda give just the right lift.
The raspberry filling is thick enough to hold between layers without making the cake soggy. The chocolate mousse adds lightness, creating a creamy contrast to the denser cake, and the buttercream frosting binds everything while adding richness.
Each element supports the others, resulting in a cake that holds its shape, slices cleanly, and delivers full flavor in every piece.
Amazing Serving Ideas
Amazing serving ideas for chocolate raspberry mousse cake recipe include placing slices on pretty dessert plates and garnishing with fresh raspberries or edible flowers for a pop of color.
A light dusting of powdered sugar or cocoa powder adds a delicate touch. Drizzling warm chocolate ganache over the top enhances the chocolate richness and makes it look decadent.
Serving each slice with a small scoop of vanilla ice cream or a spoonful of whipped cream adds creaminess and balances the tart raspberry layer. For a special touch, add a few chocolate shavings or curls on top to elevate presentation.
Top Baking Tips
1. Let eggs, butter, and sour cream sit out until they reach room temperature. This helps the batter mix smoothly and prevents lumps.
2. Always sift cocoa powder, flour, and powdered sugar before adding them. It keeps the texture light and makes the cake and mousse fluffy.
3. Use a kitchen scale to weigh ingredients whenever possible. This keeps the measurements exact and avoids surprises in the texture or sweetness.
4. Make sure the cake layers are completely cool before spreading mousse or frosting. Warm layers can melt the mousse and ruin the shape.
5. After assembling, put the cake in the fridge for a few hours. This lets the mousse and raspberry filling firm up, making it easy to cut clean slices.
Best Variations
➤ White Chocolate Raspberry Mousse Cake: Replace the dark chocolate in the mousse and frosting with white chocolate for a sweeter, creamy version.
➤ Chocolate Hazelnut Raspberry Cake: Add a layer of hazelnut spread or crushed toasted hazelnuts between the cake layers for a nutty, rich flavor.
➤ Berry Medley Cake: Combine raspberries with blueberries or blackberries in the filling for a more colorful and fruity taste.
➤ Mocha Chocolate Raspberry Cake: Mix a teaspoon of espresso or strong coffee into the cake and mousse to enhance the chocolate depth.
➤ Almond Crunch Raspberry Cake: Add toasted almond slices between the layers or on top for extra texture and a nutty accent.

Thaw frozen slices in the refrigerator for a few hours before serving. Chilling helps the mousse and raspberry layers hold their shape and keeps the cake creamy and delicious.
