Ingredients You’ll Need
Gathering these simple yet essential ingredients is the first step to creating a Chocolate Raspberry Mousse Cake Recipe that’s bursting with flavor and perfect texture. Each ingredient plays a crucial role, from the rich cocoa powder that builds the chocolate base to the fresh raspberry puree that brightens the mousse with natural fruitiness.
- Sugar (1 cup / 200g): Sweetens the cake base and the mousse, balancing richness with just the right amount of sweetness.
- Unsalted butter (½ cup / 115g), melted: Adds moistness and a velvety texture to the chocolate base without overpowering other flavors.
- Large eggs (2): Bind the ingredients together and help create the dense, fudgy brownie texture for the cake base.
- All-purpose flour (½ cup / 60g): Provides the structure needed for the cake while keeping it tender.
- Unsweetened cocoa powder (½ cup / 50g): Gives that deep, intense chocolate flavor that makes this dessert irresistible.
- Heavy cream (1 cup / 250ml): Whipped to stiff peaks, it forms the luscious, airy texture of the raspberry mousse topping.
- Raspberry puree (½ cup / 120g): Fresh and vibrant, it infuses the mousse with a bright fruity tartness to lift the chocolate.
- Sugar (¼ cup / 50g): Sweetens the raspberry mousse just enough while preserving its natural tang.
- Gelatin powder (1 teaspoon): Ensures the mousse sets perfectly for clean slices and a delightful mouthfeel.
- Water (2 tablespoons): Used to bloom the gelatin, making it easy to incorporate smoothly into the raspberry mixture.
How to Make Chocolate Raspberry Mousse Cake Recipe
Step 1: Prepare and Bake the Chocolate Base
Start by preheating your oven to 350°F (175°C) and greasing a 9-inch cake pan lined with parchment paper. In a mixing bowl, whisk together the sugar and melted butter until combined. Then, beat in the eggs for a smooth batter. Sift together the flour and cocoa powder before folding them into the wet ingredients, ensuring the batter is perfectly smooth. Pour the batter into your pan and bake for about 20-25 minutes until a toothpick comes out clean. Let the brownie cool completely in its pan—it’s the sturdy, fudgy foundation your cake deserves.
Step 2: Bloom the Gelatin
While the cake cools, sprinkle the gelatin powder over two tablespoons of water and let it sit for 5 minutes. Blooming the gelatin is a crucial step that ensures it dissolves fully later without lumps in your raspberry layer.
Step 3: Prepare the Raspberry Mousse Mixture
Warm the raspberry puree and sugar over low heat until the sugar dissolves completely, keeping an eye on it so it doesn’t boil. Take it off the heat and stir in the bloomed gelatin until it melts smoothly into the fruity syrup. Allow this mixture to cool to room temperature before moving to the next step, so it doesn’t deflate your whipped cream.
Step 4: Whip the Cream and Fold in Raspberry
Whip the heavy cream in a chilled bowl until you get stiff peaks—a sign that the mousse will be wonderfully light and airy. Gently fold the cooled raspberry mixture into the whipped cream, taking your time to keep airiness intact. This is where your mousse takes shape, bursting with fresh raspberry flavor and cloud-like texture.
Step 5: Assemble and Chill the Cake
Carefully remove the cooled brownie base from the pan to a serving plate. Spread the raspberry mousse evenly over the top, smoothing it to every edge. Pop the entire cake into the refrigerator for at least 4 hours, allowing the mousse to set firmly. This chilling step transforms your cake from a promise into a showstopper, with clean slices and an elegant look.
How to Serve Chocolate Raspberry Mousse Cake Recipe
Garnishes
The beauty of this cake shines when adorned with simple garnishes. Fresh raspberries scattered atop add a pop of color and a fresh fruity note. A light dusting of cocoa powder or powdered sugar can create a delicate finish. For an extra touch of decadence, consider shavings of dark chocolate or a few mint leaves for a refreshing green contrast.
Side Dishes
Pairing your Chocolate Raspberry Mousse Cake Recipe with a simple side can elevate the experience even more. A scoop of vanilla bean ice cream or a dollop of freshly whipped cream complements both the chocolate richness and raspberry tartness. If you prefer a drink, a cup of strong espresso or a glass of crisp champagne will balance the flavors wonderfully.
Creative Ways to Present
Presentation can turn your cake into the centerpiece of any gathering. Try serving individual portions in clear glass cups by layering brownie chunks and raspberry mousse for an elegant parfait vibe. Or plate each slice with a drizzle of raspberry coulis and a sprinkle of toasted almond slivers. For a festive look, arrange slices on a decorative platter surrounded by edible flowers.
Make Ahead and Storage
Storing Leftovers
Your Chocolate Raspberry Mousse Cake Recipe keeps beautifully covered in the refrigerator for up to 3 days. Use an airtight container or wrap the cake tightly with plastic wrap to maintain freshness and prevent the mousse from absorbing fridge odors. Leftover slices stay moist and flavorful, making them perfect for a sweet treat anytime.
Freezing
While freezing this mousse cake is possible, it’s best to freeze before assembling the mousse or only freeze the brownie base separately for optimal texture. Freezing the full cake might cause the mousse to become grainy. If you choose to freeze, wrap the cake well in plastic wrap followed by foil and thaw overnight in the fridge before serving.
Reheating
This dessert is best enjoyed chilled, so reheating isn’t recommended. However, if you prefer your chocolate slightly warm, gently warm a slice in the microwave for 10-15 seconds—just enough to soften but not melt the mousse. This way, you maintain the cake’s delightful contrast of textures and flavors.
FAQs
Can I use fresh raspberries instead of raspberry puree?
Absolutely! You can blend fresh raspberries into a puree yourself for a fresher flavor, just make sure to strain out seeds for a smooth mousse. Using fresh fruit can brighten the mousse and enhance its natural vibrancy.
Do I need to use gelatin in this recipe?
Gelatin is important for stabilizing the mousse so it sets firmly and slices cleanly. If you’re looking for a vegetarian alternative, agar-agar can work, but it requires different handling regarding temperature and texture.
Can I make this cake gluten-free?
Yes, simply swap the all-purpose flour with a gluten-free blend that measures cup for cup. Check that your cocoa powder and other ingredients are gluten-free as well to keep the cake safe for those with sensitivities.
How long does the mousse need to set in the refrigerator?
It takes at least 4 hours in the fridge for the mousse to set properly. If you have time, chilling overnight will yield the best texture and make slicing easier.
Can I prepare this cake a day in advance?
Definitely! In fact, making the cake a day ahead allows the flavors to develop even more. Just cover and refrigerate it and take it out about 15 minutes before serving for the best experience.

There’s something truly magical about this Chocolate Raspberry Mousse Cake Recipe that makes it a standout dessert for any occasion.

Description
Chocolate Raspberry Mousse Cake is a decadent dessert featuring a rich chocolate brownie base topped with a light and airy raspberry mousse. The cake combines the deep flavors of cocoa with the fresh tartness of raspberries, making it perfect for special occasions or an indulgent treat.
Ingredients
Brownie Base
- 1 cup (200g) sugar
- ½ cup (115g) unsalted butter, melted
- 2 large eggs
- ½ cup (60g) all-purpose flour
- ½ cup (50g) unsweetened cocoa powder
Raspberry Mousse
- 1 cup (250ml) heavy cream
- ½ cup (120g) raspberry puree
- ¼ cup (50g) sugar
- 1 teaspoon gelatin powder
- 2 tablespoons water
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and line a 9-inch (23cm) round cake pan with parchment paper to ensure the cake does not stick and cooks evenly.
- Mix Wet Ingredients: In a mixing bowl, combine sugar and melted butter. Add the eggs and mix thoroughly until the mixture is smooth and well combined.
- Add Dry Ingredients: Sift the all-purpose flour and unsweetened cocoa powder into the wet ingredients, stirring gently until the batter is smooth and free of lumps.
- Bake Brownie Base: Pour the batter into the prepared cake pan and bake for 20-25 minutes. To check doneness, insert a toothpick into the center; it should come out clean or with few moist crumbs.
- Cool Brownie: Allow the brownie base to cool completely in the pan. This helps it set properly and prevents breaking when assembling the mousse layer.
- Bloom Gelatin: In a small bowl, sprinkle the gelatin powder over 2 tablespoons of water and let it bloom for 5 minutes, allowing it to absorb the water and soften.
- Prepare Raspberry Mixture: Heat the raspberry puree and sugar in a saucepan over low heat until the sugar dissolves. Remove from heat and stir in the bloomed gelatin until completely dissolved and smooth.
- Cool Raspberry Mixture: Let the raspberry and gelatin mixture cool to room temperature to prevent melting the whipped cream later.
- Whip Cream: In a separate bowl, whip the heavy cream until stiff peaks form, indicating the cream is firm enough to hold its shape.
- Combine Mousse: Gently fold the cooled raspberry mixture into the whipped cream, mixing carefully to keep the mousse light and airy.
- Assemble Cake: Once the brownie base has cooled, remove it from the cake pan and place it on a serving platter.
- Spread Mousse: Spread the raspberry mousse evenly over the brownie base, creating a smooth top layer.
- Chill Cake: Refrigerate the assembled cake for at least 4 hours, allowing the mousse to fully set into a light and airy texture perfect for slicing and serving.
Notes
- Ensure the brownie base is completely cooled before adding the mousse to prevent melting or collapsing the mousse layer.
- For best raspberry puree, use fresh or thawed raspberries blended and strained to remove seeds.
- Gelatin bloom is essential for mousse stability; do not skip or use substitutes without adjusting technique.
- Whip cream to stiff peaks for a stable mousse that holds shape when sliced.
- Store leftovers refrigerated for up to 3 days for optimal freshness.
