Ingredients You’ll Need
The beauty of this Heavenly Raspberry Chocolate Mousse Cake Recipe lies in its use of simple yet thoughtfully chosen ingredients. Each component plays a crucial role: the chocolate cake base offers rich depth and softness, while the raspberry mousse brings fresh brightness and a silky texture. The ganache adds an elegant shine and smooth finish that pulls everything together perfectly.
- All-purpose flour: The foundation for your tender and structured chocolate cake layers.
- Unsweetened cocoa powder: Adds deep, chocolatey richness without overpowering the raspberries.
- Granulated sugar: Sweetens both the cake and raspberry layers, balancing flavors beautifully.
- Baking powder and baking soda: These leavening agents ensure your cake rises light and fluffy.
- Salt: Enhances the chocolate’s flavor and balances sweetness.
- Large eggs: Provide structure and moisture to keep the cake tender.
- Whole milk: Adds creaminess and lightness to the cake batter.
- Vegetable oil: Keeps the cake incredibly moist and soft.
- Vanilla extract: Brings a warm, fragrant note that complements both chocolate and raspberry.
- Boiling water: Intensifies the cocoa flavor and helps meld the batter for a tender crumb.
- Fresh raspberries: The stars of the mousse, providing tartness and vibrant color.
- Gelatin powder: Sets the raspberry mousse to a delicate, airy consistency.
- Heavy cream: Whipped to perfection for the mousse and ganache, lending creaminess throughout.
- Confectioners sugar: Sweetens and stabilizes the mousse’s whipped cream base.
- Semi-sweet chocolate chips: Melted for the ganache, offering that intense chocolate finish.
How to Make Heavenly Raspberry Chocolate Mousse Cake Recipe
Step 1: Bake the Chocolate Cake
Start by preheating your oven and preparing two round cake pans with parchment paper and a little grease. Mix all your dry ingredients for the chocolate cake in one bowl, then whisk the wet ingredients in another. Slowly combine them and stir in boiling water to deepen that rich chocolate flavor. Pour the batter evenly into your pans and bake until a toothpick comes out mostly clean. Once baked, let the layers cool completely — this step is crucial for the mousse to set properly later!
Step 2: Prepare the Raspberry Mousse
While your cake cools, blend fresh raspberries with sugar until smooth. Strain to remove seeds for a velvety texture. Dissolve gelatin powder in a small amount of warm water, then stir it into the raspberry puree. Whip heavy cream with confectioners sugar until soft peaks form, and gently fold it into your raspberry mixture. Chill this mousse in the fridge so it sets just right — airy but firm, perfect for layering.
Step 3: Assemble the Cake
Place one chocolate cake layer on your serving plate. Spread a generous layer of raspberry mousse over it, smoothing with a spatula. Add the second chocolate cake layer on top and cover the whole cake with remaining mousse or reserve it for serving. This combination creates layers that contrast texture and flavor in the most delightful way.
Step 4: Make and Add the Chocolate Ganache
Warm heavy cream until it just starts to simmer, then pour it over your semi-sweet chocolate chips. Let them sit a minute, then stir until silky and smooth. Pour this exquisite ganache over the assembled cake, allowing it to drip gently down the sides for a stunning, glossy finish. Chill once more until the ganache sets.
Step 5: Garnish and Serve
Finish your masterpiece by adorning it with fresh raspberries on top. This not only adds a burst of color but also ties the raspberry flavor through every bite. Your Heavenly Raspberry Chocolate Mousse Cake Recipe is now ready to dazzle your guests.
How to Serve Heavenly Raspberry Chocolate Mousse Cake Recipe
Garnishes
Fresh raspberries are the natural choice for garnishing this cake, adding juicy bursts and lively color. You can also sprinkle finely chopped dark chocolate or delicate mint leaves for an extra layer of presentation and flavor. These simple touches elevate your dessert from delicious to show-stopping.
Side Dishes
This cake shines best as the star dessert, but pairing it with a light and fresh side, like a bowl of mixed berries or a crisp citrus salad, balances its richness. A small scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream can also complement the mousse without competing with the flavors.
Creative Ways to Present
For a special occasion, slice your Heavenly Raspberry Chocolate Mousse Cake Recipe into individual portions and serve on elegant dessert plates with artistic drizzles of raspberry coulis or chocolate sauce. Adding edible flowers or a dusting of powdered sugar creates a beautiful finishing touch that makes every slice feel like a celebration.
Make Ahead and Storage
Storing Leftovers
This cake keeps incredibly well in the refrigerator for up to three days. Cover it with a cake dome or plastic wrap to prevent it from absorbing other odors and to keep the mousse fresh and creamy. When you slice into leftovers, you’ll still experience that perfect balance of moist cake and airy mousse.
Freezing
If you want to save this delight for later, you can freeze the cake. Wrap it tightly in plastic wrap followed by aluminum foil to protect against freezer burn. When ready, thaw it in the refrigerator overnight to maintain texture and flavors. Avoid freezing for more than a month for the best results.
Reheating
Since this is a mousse-based cake, reheating is not recommended as it can alter the texture and cause separation. Instead, enjoy this Heavenly Raspberry Chocolate Mousse Cake Recipe chilled for the perfect melt-in-your-mouth experience every time.
FAQs
Can I use frozen raspberries for the mousse?
Yes, you can, but be sure to thaw and drain them well to remove excess liquid. This helps keep the mousse from becoming too watery and ensures it sets nicely.
Is there a substitute for gelatin in the raspberry mousse?
If you prefer a vegetarian option, agar-agar can work as a substitute, but make sure to follow the package instructions for proper use, as it behaves differently than gelatin.
Can I make this cake gluten-free?
Absolutely! Replace the all-purpose flour with a gluten-free blend that’s designed for baking. The rest of the ingredients remain the same for that luscious flavor and texture.
How long does this cake take to assemble and chill?
While baking the cake takes about 30-35 minutes, chilling the raspberry mousse and the assembled cake is essential and generally takes a few hours total. Planning ahead ensures the perfect texture and taste.
What type of chocolate works best for the ganache?
Semi-sweet chocolate chips are ideal because they provide a balanced sweetness that pairs wonderfully with the tart raspberry mousse without overwhelming it.
Final Thoughts
Making this Heavenly Raspberry Chocolate Mousse Cake Recipe is such a rewarding experience because it brings together stunning flavors and elegant textures with simple ingredients and steps.

- 2 tsp gelatin powder
- 2 cups heavy cream
- 1/2 cup confectioners sugar
For the Chocolate Ganache:
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream
Instructions
- Bake the Chocolate Cake: Preheat your oven and prepare two cake pans by greasing and flouring them. In a large mixing bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk the eggs, milk, vegetable oil, and vanilla extract. Combine the wet and dry ingredients gradually, then stir in the boiling water carefully to create a smooth batter. Pour the batter evenly into the pans and bake until a toothpick inserted comes out clean. Let the cakes cool completely before assembling.
- Prepare the Raspberry Mousse: Gently puree the fresh raspberries with granulated sugar until smooth. Sprinkle the gelatin powder over a small amount of cold water to bloom, then melt it gently and combine with the raspberry puree. In a separate bowl, whip the heavy cream with confectioners sugar until stiff peaks form. Fold the raspberry mixture gently into the whipped cream, ensuring a smooth mousse consistency. Chill the mousse in the refrigerator until set.
- Assemble the Cake: Once the cake layers have completely cooled, place one layer on your serving plate. Spread a generous, even layer of raspberry mousse over the cake layer. Top with the second cake layer and cover the entire cake with the remaining mousse, smoothing it evenly. Refrigerate the assembled cake to allow the mousse to firm up.
- Prepare and Add the Chocolate Ganache: Heat the heavy cream in a small saucepan until it just begins to simmer. Pour over the semi-sweet chocolate chips in a bowl and let sit for a few minutes. Stir gently until smooth and glossy. Pour the ganache evenly over the top of the chilled cake, allowing it to drip slightly down the sides.
- Garnish and Serve: Decorate the top of the cake with fresh raspberries arranged decoratively. Refrigerate the cake for at least an hour to set the ganache and mousse fully before slicing and serving. Enjoy this luscious and sophisticated dessert that combines rich chocolate and vibrant raspberry flavors.

- Bloom gelatin properly to avoid lumps in the mousse.
- You can substitute fresh raspberries with frozen ones, thawed and drained, if fresh are unavailable.
- For a more intense chocolate flavor, use high-quality cocoa powder and chocolate chips.
- This cake is best served chilled and consumed within 2-3 days.
