Ingredients You’ll Need
The beauty of this Dark Chocolate Raspberry Mousse Cake lies in its simplicity. Each ingredient is carefully chosen to create that perfect harmony of flavor, texture, and color that makes this cake unforgettable. From the rich cocoa to the fresh vanilla, every component plays a crucial role.
- 1 cup All-purpose flour: Provides the structure and body to the cake, ensuring it holds up perfectly under the mousse layer.
- 1/2 cup Unsweetened cocoa powder: Delivers an intense, deep chocolate flavor, forming the heart of the cake’s rich character.
- 1 teaspoon Baking powder: Works to give the cake a light rise, keeping it from feeling too dense.
- 1/2 teaspoon Baking soda: Combines with baking powder to help create a tender crumb with excellent texture.
- 1/4 teaspoon Salt: Enhances all the flavors, balancing the sweetness and brightening the chocolate notes.
- 1/2 cup Unsalted butter: Adds moisture and richness, making the cake tender and soft.
- 1 cup Granulated sugar: Sweetens the cake just right, without overpowering the chocolate or raspberry elements.
- 2 large Eggs: Provide necessary moisture and help bind the ingredients for a stable cake base.
- 1 teaspoon Vanilla extract: Adds a warm, sweet aromatic note that complements the cocoa perfectly.
How to Make Dark Chocolate Raspberry Mousse Cake
Step 1: Prepare the Cake Base
Start by preheating your oven to 350°F (175°C) and greasing your cake pan. In a large bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking powder, baking soda, and salt. In a separate bowl, cream the softened unsalted butter with granulated sugar until light and fluffy, then beat in the eggs one at a time, followed by the vanilla extract. Slowly fold the dry ingredients into the wet mixture, being careful not to overmix. Pour this luscious batter into your pan and bake for about 25-30 minutes or until a toothpick inserted comes out clean. Let the cake cool completely before moving on.
Step 2: Make the Raspberry Mousse
While the cake cools, it’s time to prepare the raspberry mousse, the star of the show. Fresh or frozen raspberries can be pureed and then strained to remove seeds, ensuring an ultra-smooth mousse texture. Whip heavy cream until stiff peaks form, then gently fold in the raspberry puree along with a touch of sugar to balance the tartness. This step brings that light, airy, and fruity layer which contrasts beautifully with the dense chocolate cake below.
Step 3: Assemble the Layers
Once the cake is completely cooled, slice it horizontally to create two even layers or leave it as a single base if you prefer more mousse. Spread a generous layer of your raspberry mousse over the cake with a spatula, smoothing it evenly. If you’ve sliced the cake, add the mousse between layers and on top. Refrigerate so the mousse can set into the cake, allowing those flavors to meld beautifully.
Step 4: Add the Finishing Touches
For the final flourish, you might sprinkle fresh raspberries or a dusting of cocoa powder over the top. Some like to add chocolate shavings or curls for extra flair and texture. The Dark Chocolate Raspberry Mousse Cake is now ready to please your eyes and your taste buds!
How to Serve Dark Chocolate Raspberry Mousse Cake

Garnishes
Garnishing is where presentation meets flavor. Fresh raspberries scattered on top or a light dusting of powdered sugar can elevate your cake’s appearance. You could also drizzle a little raspberry coulis or melted dark chocolate for that chef’s touch that makes every serving unforgettable.
Side Dishes
Pair your Dark Chocolate Raspberry Mousse Cake with a bright, refreshing side like a simple mixed berry salad or a scoop of vanilla bean ice cream. These companions help balance the richness of the mousse while enhancing the fruitiness of the raspberries. A cup of strong espresso or rich black tea also makes a delightful pairing for those who love a contrast in flavor profiles.
Creative Ways to Present
Serve individual portions in clear glasses or trifle bowls to showcase the luscious layers of cake and mousse. For an elegant party presentation, add edible flowers or gold leaf accents. You could even experiment with layering mini cups, alternating layers of cake, mousse, and fresh raspberries, making it easier for guests to enjoy without utensils.
Make Ahead and Storage
Storing Leftovers
Leftover Dark Chocolate Raspberry Mousse Cake should be tightly covered and stored in the refrigerator. The mousse is delicate and maintains its texture and flavor best when kept chilled. It’s best consumed within 3-4 days for optimum freshness.
Freezing
You can freeze this cake if you want to make it ahead of time. Wrap the cake securely in plastic wrap and then foil to prevent freezer burn. When ready to enjoy, thaw in the refrigerator overnight. Keep in mind that the texture of the mousse might shift slightly, but the flavors will remain delicious.
Reheating
Because the cake contains mousse, reheating is not recommended. Instead, serve it chilled to fully appreciate the creamy texture and fresh raspberry taste. Taking it straight from the fridge gives you the best experience.
FAQs
Can I use frozen raspberries for the mousse?
Absolutely! Frozen raspberries work wonderfully as long as you thaw and strain them before making the mousse to avoid excess moisture and seeds.
Is this cake suitable for special occasions?
Definitely. The rich, elegant combination of dark chocolate and raspberry mousse makes it a perfect centerpiece for birthdays, anniversaries, or dinner parties.
Can I make this cake vegan or dairy-free?
With some ingredient swaps like using plant-based butter, non-dairy cream, and egg replacers, you can adapt this recipe to be vegan, but it might require a bit of experimentation to get the mousse texture just right.
How long does it take to prepare this cake?
From start to finish, including baking and chilling, it typically takes about 3-4 hours, so it’s perfect for making ahead of time.
Can I add other fruits besides raspberries?
Yes! While raspberries offer a perfect balance to dark chocolate, you can experiment with strawberries, cherries, or blackberries for unique flavor twists.

Ingredients
Chocolate Cake
- 1 cup All-purpose flour
- 1/2 cup Unsweetened cocoa powder
- 1 teaspoon Baking powder
- 1/2 teaspoon Baking soda
- 1/4 teaspoon Salt
- 1/2 cup Unsalted butter, softened
- 1 cup Granulated sugar
- 2 large Eggs
- 1 teaspoon Vanilla extract
Raspberry Mousse
- 1 1/2 cups Fresh or frozen raspberries
- 1/4 cup Granulated sugar
- 1 tablespoon Lemon juice
- 1 envelope Unflavored gelatin (about 2 1/2 teaspoons)
- 2 tablespoons Cold water
- 1 cup Heavy whipping cream, cold
Instructions
- Prepare the Cake Batter: Preheat the oven to 350°F (175°C). In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. In a separate large bowl, beat the softened butter with sugar until creamy. Add eggs one at a time, mixing well after each addition, then blend in the vanilla extract. Gradually add the dry ingredients into the wet mixture, mixing until just combined.
- Bake the Cake: Grease and flour an 8-inch round cake pan. Pour the batter into the pan and smooth the top. Bake for about 30-35 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven, allow to cool completely in the pan on a wire rack.
- Make Raspberry Puree: In a small saucepan, combine the raspberries, sugar, and lemon juice over medium heat. Cook for 5-7 minutes, stirring occasionally, until the raspberries break down and the mixture thickens slightly. Strain through a fine mesh sieve to remove seeds. Let cool.
- Bloom the Gelatin: Sprinkle the gelatin over cold water in a small bowl and allow it to bloom (absorb water and soften) for about 5 minutes. Then gently warm the gelatin in the microwave or over a double boiler until melted and smooth. Stir the melted gelatin into the cooled raspberry puree.
- Whip the Cream: In a chilled bowl, whip the heavy cream until soft peaks form. Gently fold the raspberry gelatin mixture into the whipped cream until fully combined and smooth, forming the mousse.
- Assemble the Cake: Once the cake is completely cooled, remove it from the pan and place it on a serving plate. Spread the raspberry mousse evenly over the top of the cake, smoothing with a spatula. Refrigerate the cake for at least 4 hours or preferably overnight to allow the mousse to set properly.
- Serve: Before serving, garnish with fresh raspberries or a dusting of cocoa powder if desired. Slice and enjoy the rich layers of chocolate cake paired with the light, fruity raspberry mousse.
Notes
- Ensure the cake is completely cool before spreading the mousse to prevent it from melting.
- If fresh raspberries are out of season, frozen raspberries can be used but thaw and strain well to remove excess liquid.
- Use high-quality dark cocoa powder for the best chocolate flavor.
- Store leftovers covered in the refrigerator for up to 3 days.
- For a gluten-free version, substitute the all-purpose flour with a gluten-free flour blend.
