Ingredients You’ll Need

The magic of this Chocolate Raspberry Mousse Cake comes from a delightful cast of straightforward yet hardworking ingredients. Each one is handpicked to create a balance of richness, brightness, and texture, making every layer truly sing on your palate.

Chocolate Cake Mix: Simple and reliable, it’s the quick and easy base that bakes up moist and fluffy to hold all those luscious mousse layers.
Eggs, Oil, and Water: These are what bring your cake mix to life—check your box directions so you get the perfect texture every time.
Semi-Sweet Chocolate (8 oz): Deep and velvety, this chocolate adds a decadent richness to the chocolate mousse without overwhelming the palate.
Heavy Whipping Cream (2 cups + 1 ½ cups): This is the secret to billowy, cloud-like mousse layers that melt in your mouth.
Powdered Sugar (¼ cup + 2 tbsp): It gently sweetens each mousse without making it heavy or gritty.
Vanilla Extract (1 tsp): Just a splash brings warmth and rounds out the chocolate flavor.
Fresh or Frozen Raspberries (2 cups): These little gems infuse the raspberry mousse with bold, tart flavor and vibrant color.
Sugar (¼ cup): This balances the natural tartness of the raspberries for a perfectly sweet mousse.
Lemon Juice (1 tbsp): Brightens the raspberries and highlights their fresh flavor.
Powdered Gelatin (2 tsp): Essential for the mousse structure—it gives just enough hold without making things rubbery.
Cold Water (¼ cup): Used to bloom the gelatin, it ensures the raspberry mousse stays airy and smooth.
Fresh Raspberries & Chocolate Shavings (for garnish): Finish your cake like a pro with these classic, irresistible toppings.

How to Make Chocolate Raspberry Mousse Cake

Step 1: Bake the Chocolate Cake

Start your Chocolate Raspberry Mousse Cake adventure by mixing up your favorite chocolate cake mix according to the package directions, using the eggs, oil, and water as called for. Once baked, let it cool completely in the pan—this creates a sturdy but tender foundation for all those heavenly mousse layers to come.

Step 2: Whip Up the Chocolate Mousse

Melt your semi-sweet chocolate gently, either over a double boiler or in the microwave using short bursts and plenty of stirring. In a large bowl, whip the heavy cream with powdered sugar and vanilla until it forms soft peaks. Gently fold the cooled, melted chocolate into the whipped cream, creating a smooth, luxurious mousse. Pop it in the fridge to set up while you tackle the next step.

Step 3: Make the Raspberry Puree

Blend your raspberries together with sugar and lemon juice until completely smooth. For a silky-smooth mousse, strain the mixture through a fine mesh sieve to remove the seeds—this extra step makes a world of difference for a dessert as elegant as Chocolate Raspberry Mousse Cake.

Step 4: Set the Gelatin

Sprinkle the powdered gelatin over cold water and let it stand for about five minutes to “bloom.” Once bloomed, gently heat the gelatin (either in the microwave or over low heat on the stove) until it’s fully dissolved. Stir this directly into your raspberry puree, ensuring it stays vibrant and smooth.

Step 5: Whip and Fold Raspberry Mousse

Whip another batch of heavy cream with powdered sugar until soft peaks just form. Fold this whipped cream into the prepared raspberry mixture in batches, being careful not to deflate it. Chill until the mousse is just starting to set but still spreadable.

Step 6: Layer and Chill

Now comes the fun part—assembly! Place your cooled chocolate cake layer in the bottom of a springform pan. Carefully spread the chocolate mousse evenly over the cake, then gently layer the raspberry mousse over the top. Smooth the surface, cover, and chill the entire Chocolate Raspberry Mousse Cake for at least 4 hours (overnight is ideal) so the layers firm up beautifully.

Step 7: Garnish and Serve

Unmold the cake and prepare for oohs and ahhs! Heap fresh raspberries and scatter dark chocolate shavings over the top for a bakery-worthy finish. Each slice looks as gorgeous as it tastes.

How to Serve Chocolate Raspberry Mousse Cake

Garnishes

For a picture-perfect finish, I love crowning my Chocolate Raspberry Mousse Cake with a generous handful of glossy fresh raspberries, a shower of chocolate shavings, or even a few curls of white chocolate for a playful touch. If you’re feeling fancy, a sprig of mint adds a splash of green that pops against those deep chocolate and raspberry hues.

Side Dishes

Keep it classic and let the cake shine! Pair each slice with a scoop of vanilla bean ice cream, a dollop of barely-sweetened whipped cream, or even a few lemon shortbread cookies. A strong cup of coffee or a flute of raspberry-chilled champagne will take your dessert experience to the next level.

Creative Ways to Present

Try serving mini versions of Chocolate Raspberry Mousse Cake in individual ramekins or jars for easy entertaining and portion control. Take it up a notch for a special event by drizzling each slice with homemade raspberry sauce or a warm chocolate ganache. For a rustic-chic look, finish with edible flowers scattered on top—totally Instagram-worthy!

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, simply cover the cake or place slices in an airtight container in the fridge. The Chocolate Raspberry Mousse Cake keeps beautifully for up to four days—just be sure it stays chilled so the mousse layers remain soft and silky.

Freezing

Got extra? You can freeze individual slices by wrapping them tightly in plastic wrap and then foil. Store these treasures in an airtight container for up to a month! When you’re ready for another taste, thaw in the fridge overnight for best texture and flavor.

Reheating

No reheating needed—just pull your slice straight from the fridge or let it sit out for 10-15 minutes to take off the chill. If frozen, allow the cake to thaw fully in the fridge before enjoying. Warming isn’t recommended, as the mousse will lose its beautiful texture.

FAQs

Can I make Chocolate Raspberry Mousse Cake without a springform pan?

Absolutely! While a springform pan helps with easy unmolding and a lovely layered look, you can use a deep cake pan lined with parchment for lifting out the cake. Just be extra gentle when removing.

Can I use other berries instead of raspberries?

Yes, feel free to swap in strawberries, blackberries, or a mix—just adjust the sugar and lemon to taste, since berries vary in sweetness and tartness.

How do I keep the mousse layers from mixing together?

Make sure each mousse layer is softly set before spreading over the previous one. Gently smoothing each layer with a spatula and chilling between steps can help keep those pretty layers distinct.

Is this recipe gluten-free?

The core mousse layers are naturally gluten-free, but be sure to use a gluten-free chocolate cake mix if you’re baking for someone with allergies or sensitivities. Always check all your ingredients!

Can I make this cake a day ahead?

Yes, in fact, the flavors mingle and the mousse sets up even better if you assemble your Chocolate Raspberry Mousse Cake the night before serving. Just garnish right before serving for maximum freshness.
