Ingredients You’ll Need

Every ingredient in this Chocolate Raspberry Mousse Cake Recipe plays a key role in creating its signature flavor and texture. From the creamy double cream to the nuanced espresso powder in the sponge, I’ve found that quality and balance truly make the difference.

• Eggs: Use large eggs at room temperature for better whipping and smoother batter.
• Light brown sugar & Granulated sugar: A mix adds depth and sweetness without overpowering.
• Vanilla extract: Adds warmth and rounds out the chocolate flavor beautifully.
• Plain flour (all-purpose): The base of your sponge, sifted to keep it light and airy.
• Cocoa powder: Opt for unsweetened for that intense chocolatey kick.
• Baking powder: Helps the sponge rise tenderly.
• Espresso powder: This little secret boosts the chocolate flavor magnificently.
• Salt: Just a pinch to balance the sweetness.
• Dark Chocolate 75%: Melted and folded into the sponge for a deep, rich taste.
• Powdered gelatine: Essential for setting the raspberry mousse firmly yet delicately.
• Fresh lemon juice: Enhances the raspberry’s brightness and activates the gelatin.
• Fresh raspberries: The star of the mousse; fresh is best, but frozen works well too.
• Double cream (heavy cream): Whipped to soft peaks for that cloud-like mousse texture.
• Dark Chocolate shavings and fresh raspberries: For that gorgeous finishing touch.

Variations

I love how adaptable this Chocolate Raspberry Mousse Cake Recipe is. It’s really fun to experiment with different chocolate percentages, swapping fresh berries for frozen, or even trying alternative sweeteners. Don’t hesitate to tailor it to your tastes or dietary needs!

• Dairy-Free Version: I’ve swapped double cream for coconut cream before and it worked wonderfully, just keep the whipping firm for good structure.
• Vegan Adaptation: Using agar-agar instead of gelatine and aquafaba instead of eggs can work, but the texture may be slightly different based on choices.
• Fruit Swap: If raspberries aren’t in season, blackberries or strawberries make a lovely alternative and bring their own twist.
• Chocolate Types: Feel free to try milk or white chocolate in the sponge for a milder, sweeter foundation.

How to Make Chocolate Raspberry Mousse Cake Recipe

Step 1: Create the Perfect Chocolate Sponge

Start by prepping your pan and preheating the oven to 180°C (350°F). I always grease and line a 23cm springform pan for easy release. Then, whisk together your eggs, light brown sugar, granulated sugar, and vanilla until the mixture is pale, creamy, and leaves thick ribbons when you lift your whisk—which usually takes about 4 minutes on medium-high speed. This is key to a light sponge, so don’t rush it!

Next, sift in your dry ingredients: flour, cocoa, baking powder, espresso powder, and salt. Mix gently on low speed until there are just a few streaks of flour—you want to keep those air bubbles intact. Add the melted dark chocolate and fold it carefully into the batter with a spatula, scraping the bottom well to catch any melted chocolate that’s settled. Pour the batter into the pan, tap it on the counter to pop air bubbles, smooth the surface, and bake for 15-20 minutes. The sponge is done when it springs back lightly to the touch.

Once out of the oven, I place the pan on a wire rack to cool completely. When it’s no longer hot, press the top gently with a flat glass to flatten the wrinkly surface—it makes layering the mousse neat and easy. Then cover and chill until you’re ready to assemble.

Step 2: Whip Up That Luscious Raspberry Mousse

Start by blooming your gelatine: sprinkle the powdered gelatine over fresh lemon juice and let it sit while you prepare the raspberries. Blend the raspberries until smooth, then push the puree through a fine sieve to remove the seeds, leaving you with intensely flavored raspberry pulp. I recommend scraping underneath the sieve to get every bit—it’s worth it for smoothness!

Heat the puree gently with sugar in a saucepan until simmering, then stir in the gelatine mixture until fully dissolved—just be careful not to let it boil, or your mousse won’t set properly. For extra smoothness, pass the mixture through the sieve once more before letting it cool to room temperature (usually around 20 minutes).

While that’s cooling, whip your double cream until you see soft peaks forming. Here’s a crucial tip: fold the cooled raspberry puree into the whipped cream in three parts, using a light touch to keep that airy texture intact. You want the mousse to be fluffy and hold its shape rather than become runny.

Step 3: Assemble and Chill

Pour the raspberry mousse evenly over your chilled chocolate sponge in the springform pan. Smooth the surface with an offset spatula. Now comes the hardest part—cover and refrigerate for at least three hours, but I honestly prefer overnight. This waiting time allows the mousse to set perfectly and the flavors to meld beautifully.

Step 4: Decorate and Serve

When you’re ready to serve, carefully remove the cake from the springform pan. Peel away the baking paper collar, and if needed, smooth any rough edges with a warm offset spatula—trust me, such small steps make a big difference in presentation. I love topping mine with fresh raspberries and dark chocolate shavings for that elegant, rustic look. Slice with a warm, sharp knife for clean cuts, and enjoy immediately.

How to Serve Chocolate Raspberry Mousse Cake Recipe

Garnishes

I usually stick with fresh raspberries because they add a burst of color and brightness, contrasting beautifully with the deep chocolate hues. The dark chocolate shavings on top add a lovely texture and a bit of opulence. Sometimes, I sprinkle a tiny bit of edible gold leaf for special occasions—totally optional, but it transforms the cake from homey to glam!

Side Dishes

To keep things simple, I like pairing this mousse cake with a light herbal tea or a fresh berry compote on the side for those who want an extra hit of fruit. When serving at dinner parties, a scoop of vanilla bean ice cream works wonderfully to balance the tartness of the raspberry.

Creative Ways to Present

For birthdays or celebrations, I’ve put this cake on a wooden rustic board with scattered edible flowers and fresh mint leaves. Another fun idea is layering mini portions in stemmed glasses for individual mousse cakes—great for smaller gatherings and elegant presentations!

Make Ahead and Storage

Storing Leftovers

I always store leftovers in the fridge, keeping the cake covered but still in the springform pan for protection. The mousse holds up well for up to 5 days if kept cold, although it rarely lasts that long in my house! Just avoid leaving it out at room temperature to prevent the mousse from softening too much.

Freezing

Freezing this chocolate raspberry mousse cake is totally doable and I’ve done it a few times. Wrap the cake tightly in plastic wrap, then double-wrap with aluminum foil to prevent freezer burn. It keeps well for up to 2 months. When you’re ready to indulge, thaw it overnight in the fridge—don’t try to rush thawing as the texture benefits from a slow, gentle thaw.

Reheating

This cake is best served cold, so I don’t recommend reheating. However, if you want a little warmth, letting the slices sit at room temperature for 10-15 minutes brings out the flavors without compromising the mousse texture. Avoid any microwaving since that will ruin the delicate mousse.
