Ingredients You’ll Need

Getting the ingredients right is half the fun and success of this Chocolate Raspberry Mousse Cake Recipe. I always recommend using fresh, quality raspberries for the best flavor, but frozen ones work just as well if fresh aren’t in season. The rest of the ingredients are pantry staples, which makes this recipe super convenient.

• Large eggs: Room temperature eggs whip up better, giving the sponge a light, airy texture.
• Light brown sugar & granulated sugar: A mix for balanced sweetness and depth of flavor.
• Vanilla extract: Adds warmth and enhances the chocolate tones subtly.
• Plain flour (all-purpose): The foundation for a tender sponge.
• Cocoa powder (unsweetened): For rich chocolate flavor without overpowering sweetness.
• Baking powder & espresso powder: Baking powder gives rise, and espresso powder intensifies the chocolate notes.
• Salt: Just enough to balance sweetness and bring out other flavors.
• Dark chocolate 75%: Melted for the batter—choose one you love to eat on its own for best results.
• Powdered gelatin: Essential to help your mousse set beautifully without being too firm.
• Fresh lemon juice: Adds brightness to the raspberry puree and helps the gelatin bloom.
• Fresh raspberries: The star of the mousse, bursting with tartness and vibrancy.
• Double cream (heavy cream): Cold and whipped for silky, airy mousse texture.
• Dark chocolate shavings: For decoration and a little extra chocolate indulgence at the finish.

Variations

I love making this Chocolate Raspberry Mousse Cake Recipe my own depending on the season or occasion—feel free to play around with flavors and textures. Trust me, a little customization can make it uniquely yours!

• Use frozen raspberries: When fresh raspberries are pricey or out of season, thawed frozen raspberries work beautifully without sacrificing flavor.
• Swap the chocolate percentage: If you prefer a sweeter cake, go for 60% dark chocolate instead of 75% and see how the flavor softens delightfully.
• Make it vegan: Try swapping gelatin for agar-agar, plant-based cream alternatives, and egg replacers, although this will slightly change the texture.
• Add fresh herbs: A touch of chopped mint or basil stirred into the mousse adds a surprising fresh note that my family oddly adores.

How to Make Chocolate Raspberry Mousse Cake Recipe

Step 1: Prepare and Bake the Chocolate Sponge

First things first: Grease and line a 23cm (9-inch) springform pan well—this ensures your cake will slip out easily after chilling. Preheat your oven to 180°C (350°F). In a medium bowl, whisk together eggs, light brown sugar, granulated sugar, and vanilla extract using an electric mixer on medium-high speed for about 4 minutes. You’ll know you’re there when the mixture lightens in color and falls in ribbons when the whisk is lifted – this step is vital for that airy sponge!

Now sift in the flour, cocoa powder, baking powder, espresso powder, and salt. Mix on low speed until you still see a few flour streaks. Then, gently fold in the melted dark chocolate with a rubber spatula — make sure to scrape the bowl’s base so the chocolate incorporates without deflating your batter. Pour this mixture into your prepared pan, tap it on your countertop a couple of times to release air bubbles, and smooth the top with an offset spatula if needed.

Bake for 15-20 minutes until the sponge springs back when pressed in the center. I found that the slightly wrinkled top can be flattened perfectly by pressing down gently with a flat glass or measuring cup base once it cools. Let it cool completely at room temperature, then cover and chill in the fridge until ready for the delicious mousse layer.

Step 2: Make the Raspberry Mousse Filling

Sprinkle the powdered gelatin over fresh lemon juice in a small bowl and let this bloom (soften) while you work on the rest. Meanwhile, blend fresh raspberries until smooth, then push the puree through a fine mesh sieve to remove all seeds. This step makes the mousse silky and smooth—take your time here, it’s worth it!

Transfer the strained puree to a saucepan, add sugar, and warm gently over medium-low heat until the sugar dissolves and the mixture simmers. Stir in gelatin and keep stirring gently until fully dissolved but avoid boiling, which ruins the gelatin’s setting power. For extra smoothness, I often pass the puree through the sieve one more time to catch any gelatin lumps. Let it cool to room temperature.

In a separate cold bowl, whip the chilled double cream to soft peaks, then carefully fold in the cooled raspberry puree in three parts. Folding gently is key—you want to keep as much air in the whipped cream as possible to achieve a light and airy mousse.

Step 3: Assemble and Chill Your Cake

Pour the raspberry mousse gently over your chilled chocolate sponge in the springform pan. Use an offset spatula to smooth the surface evenly. Cover and refrigerate the entire cake for at least 3 hours to set properly—overnight if you can! This patience is truly rewarded with a mousse that holds its shape perfectly yet melts in your mouth.

Step 4: Decorate and Serve

When ready to serve, carefully remove the sides of the springform pan and peel off any baking paper collar. If the edges of your mousse need smoothing, a warm offset spatula works like magic to perfect the look. Slide the cake onto your serving plate and adorn with fresh raspberries and dark chocolate shavings. Cut slices with a warm, dry sharp knife for clean edges. Serve immediately and watch your friends and family go crazy for this beauty!

How to Serve Chocolate Raspberry Mousse Cake Recipe

Garnishes

I’m a big fan of keeping garnishes simple but elegant. Fresh raspberries and dark chocolate shavings on top highlight this cake’s flavors without overwhelming the mousse. Sometimes I add a sprig of fresh mint for a pop of color and a refreshing scent—your guests will appreciate this little touch!

Side Dishes

This cake is quite rich and satisfying on its own, but if you want to serve it alongside something, a light berry salad or a scoop of vanilla bean ice cream pairs beautifully. A crisp cup of espresso or a glass of sparkling wine can also elevate your dessert experience.

Creative Ways to Present

For special occasions, I love serving individual mousse portions in clear glass cups layered with crumbled chocolate sponge and extra raspberries—so fancy but easy! You can even pipe whipped cream rosettes on top for a festive touch. Another fun idea is to add edible gold leaf on some chocolate shavings for a little wow factor.

Make Ahead and Storage

Storing Leftovers

This mousse cake stores wonderfully when covered and kept in the refrigerator for up to 5 days. I usually leave it right in the springform pan, sealed with cling film, which keeps it fresh and helps maintain its texture perfectly. Just take it out about 10 minutes before serving for the best mouthfeel.

Freezing

I’ve frozen this cake many times and it freezes beautifully! Wrap the cake tightly in plastic wrap and then in two layers of foil to prevent freezer burn. Thaw in the fridge overnight before serving—you definitely want to avoid reheating mousse cakes, as that ruins their silky texture.

Reheating

This cake isn’t meant to be reheated, so instead enjoy it cold or at room temperature. If you find your slices a bit too firm straight from the fridge, just leave them out for 15–20 minutes before serving to bring out the flavors and soften the mousse slightly.
