Chocolate Raspberry Mousse Cake Recipe

The Chocolate Raspberry Mousse Cake is the ultimate dessert for special celebrations—or when you’re simply craving something irresistibly decadent! It’s a stunning showstopper that layers rich chocolate sponge with billowy, vibrant raspberry mousse, then tops it off with glossy chocolate shavings and tart, juicy berries. Every bite is a perfect balance of flavors and textures, making this cake as satisfying as it is beautiful.

Ingredients You’ll Need

Every component of this Chocolate Raspberry Mousse Cake depends on a handful of carefully chosen ingredients—each one playing a starring role in building flavor, striking color, and that signature creamy texture that makes this dessert so unforgettable.

• Large eggs: Whipping room-temperature eggs creates that light, aerated base for our chocolate sponge—don’t try to rush it!
• Light brown & granulated sugar: This blend brings both caramel depth and classic sweetness to the cake layers.
• Vanilla extract: Adds gentle warmth and aroma, enhancing both the sponge and the mousse.
• Plain (all-purpose) flour: Keeps the cake base soft and tender—don’t forget to sift!
• Cocoa powder: A little goes a long way to boost that pure chocolate flavor.
• Baking powder & salt: Ensures your sponge stays light, with just the right lift and balance.
• Espresso powder: Just a touch intensifies the chocolate, making flavors pop without a coffee taste.
• Dark chocolate (75%): Choose a good-quality bar—your cake’s richness depends on it!
• Powdered gelatine & lemon juice: Sets the mousse to a dreamy consistency and adds lift to the fruit flavor.
• Fresh raspberries: Plump, juicy raspberries make that mousse absolutely sing (use frozen if needed; just thaw and drain).
• Granulated sugar (for the mousse): Gently sweetens the fruit without overwhelming its tartness.
• Cold double (heavy) cream: Whips into cloud-like peaks that fold into raspberry puree for ultimate lusciousness.
• Fresh raspberries & dark chocolate shavings (for decoration): Not just pretty—these make the final bite irresistible!

Variations

One of the joys of this Chocolate Raspberry Mousse Cake is how easy it is to adapt—whether you’re catering to a certain diet or just want to change up the flavors, you have plenty of delicious options at your fingertips.

• Swap in white or milk chocolate: Use a creamy white or milk chocolate for a sweeter, lighter take on the classic.
• Gluten-free option: Substitute your favorite 1:1 gluten-free flour blend for the plain flour—so everyone can have a slice!
• Berry swap: Try making the mousse with blackberries or strawberries for a whole new twist on fruit flavor.
• Dairy-free version: Full-fat coconut cream can replace heavy cream for a luscious, non-dairy treat.

How to Make Chocolate Raspberry Mousse Cake

Step 1: Prepare the Chocolate Sponge

Start by preheating your oven to 180°C (350°F) and lining a 23cm (9-inch) springform pan with parchment. Grease it well, including all around the sides, to guarantee a flawless release. Grab a mixing bowl and whip the eggs, both sugars, and vanilla until they’re thick, pale, and leave visible trails—this airiness is the secret to that tender crumb!

Step 2: Add the Dry Ingredients and Melted Chocolate

Sift together the flour, cocoa, baking powder, espresso powder, and salt, then gently fold them into the egg mixture—keep it delicate so you don’t knock out all that precious air. Once just a few streaks of flour remain, gently swirl in the melted dark chocolate, scraping the bowl with a spatula to ensure everything is perfectly combined.

Step 3: Bake the Sponge Layer

Pour the batter into your prepared pan and tap it firmly on the counter a few times to coax out air bubbles. Smooth the top with an offset spatula if needed, then bake for 15–20 minutes. You’ll know it’s done when the center springs back to a gentle touch. Let the sponge cool completely, then use the bottom of a glass to gently press down any wrinkles for a perfectly even base.

Step 4: Make the Raspberry Mousse

Bloom your gelatin in a splash of lemon juice for a few minutes, then blend the raspberries into a smooth puree. Push the puree through a sieve to ditch those pesky seeds (hello, silky mousse!). Warm the puree with sugar, gently melt in the gelatin, then let the mixture cool completely. Meanwhile, whip cold cream into soft, billowy peaks and gently fold in the raspberry puree in thirds—this keeps your mousse light as air.

Step 5: Assemble and Chill

Pour the raspberry mousse over your cooled chocolate sponge, smoothing the top to bakery-level perfection. Cover the cake and refrigerate for at least 3 hours or (even better!) overnight—the mousse needs time to set to that signature creamy-yet-sliceable consistency.

Step 6: Decorate and Serve

When you’re ready to dazzle, gently unmold the cake, peel away any parchment, and finish with a flourish of fresh raspberries and a rain of dark chocolate shavings. Slice the Chocolate Raspberry Mousse Cake with a warm, dry knife for those picture-perfect edges and serve immediately to wild applause!

How to Serve Chocolate Raspberry Mousse Cake

Garnishes

The crowning jewels on your Chocolate Raspberry Mousse Cake are a scattering of plump fresh raspberries and a generous dusting of dark chocolate shavings. For a special touch, you can add a few mint leaves or a light snow of powdered sugar—little details that make your dessert look like it came out of a fancy patisserie.

Side Dishes

This cake pairs beautifully with a cup of freshly brewed espresso or a pot of delicate herbal tea. For a summer fête, serve alongside a scoop of vanilla bean ice cream or a dollop of lightly whipped cream to make each slice even more decadent.

Creative Ways to Present

For extra wow-factor, serve individual slices with a drizzle of raspberry coulis, a chocolate curl, or even tiny edible flowers tucked beside the berries. You could even make mini “personal” mousse cakes using a muffin tin—perfect for dinner parties or gifts!

Make Ahead and Storage

Storing Leftovers

Leftover Chocolate Raspberry Mousse Cake keeps well in the fridge for up to 5 days—simply cover it (I like to tuck the springform pan back around it for protection) and let it chill until you’re ready for another slice. The texture stays creamy and delicious so long as you keep it cool.

Freezing

You absolutely can freeze this cake! Wrap tightly in plastic wrap and a layer or two of foil, then freeze for up to two months. Thaw overnight in the refrigerator (no heating, please!) for a make-ahead treat that tastes just as stunning as fresh.

Reheating

Mousse cakes are meant to be enjoyed cold; don’t attempt to reheat or warm your Chocolate Raspberry Mousse Cake or you’ll lose that dreamy texture. If serving from the fridge, simply let the cake sit at room temperature for about 10 minutes for the softest mousse and deepest flavor.
