Every ingredient in this Chocolate Mousse Cake Recipe plays an important role, from the flour that forms the tender cake base to the heavy cream that creates that luscious, creamy mousse texture. With just a handful of essential items, you’ll achieve a dessert that’s stunning both in flavor and appearance.
- All-purpose flour: Provides structure to the cake base for a soft, tender crumb.
- Unsweetened cocoa powder: Adds deep chocolate flavor and color to the cake base.
- Baking powder and salt: Help the cake rise and enhance the overall flavor.
- Large eggs: Give the cake its lift and richness while helping bind ingredients.
- Granulated sugar: Sweetens the cake and helps achieve a light texture when beaten with eggs.
- Unsalted butter: Brings moisture and a subtle richness to the cake base.
- Vanilla extract: Elevates the flavor with warm, complementary notes.
- Semi-sweet chocolate: Provides the luscious chocolate foundation for mousse and ganache.

- Water: Used to bloom the gelatin, ensuring it dissolves evenly.
How to Make Chocolate Mousse Cake Recipe
Step 1: Prepare the Cake Base
Start by preheating your oven to 350°F (175°C) and prepping a 9-inch springform pan with grease and parchment paper. Sift together the flour, cocoa powder, baking powder, and salt to ensure your cake base has a smooth texture without lumps. In a separate bowl, whisk the eggs and sugar until the mixture turns pale and fluffy, which is key for a light cake. Gently fold in the melted butter, vanilla, and dry ingredients to create a velvety batter. Pour this batter into your pan and bake for 12 to 15 minutes until a toothpick inserted comes out clean. Let the cake cool completely in the pan while preparing the mousse.
Step 2: Make the Chocolate Mousse
Bloom the gelatin by sprinkling it over water and letting it sit for about 5 minutes. Meanwhile, melt the semi-sweet chocolate with half a cup of heavy cream carefully using a double boiler or microwave, stirring until silky smooth. Once the chocolate mixture has cooled a bit, gently microwave the gelatin mixture just enough to dissolve it, and stir it into the chocolate. Whip the remaining heavy cream to soft peaks — this lightness is what makes the mousse so airy and dreamy. Finally, fold the whipped cream gently into the chocolate blend to keep it fluffy, then spread this luscious mousse atop your cooled cake base. Refrigerate for at least 2 hours to allow the mousse to set beautifully.
Step 3: Prepare the Ganache and Assemble
Gently heat the last half cup of heavy cream until it just begins to simmer—watch closely to avoid boiling over. Pour this hot cream over the finely chopped chocolate for the ganache and stir until it becomes glossy and smooth. Let it cool just until it thickens slightly but remains pourable. Carefully pour this over your mousse layer, spreading evenly to cover every inch in rich, chocolatey goodness. Place it back in the fridge for about an hour to set the ganache, then slide a warm knife around the edges before loosening the springform pan. Your stunning, silky Chocolate Mousse Cake Recipe is ready to slice and serve cold, guaranteeing a show-stopping dessert.
How to Serve Chocolate Mousse Cake Recipe
Garnishes
Simple garnishes like fresh berries, a dusting of cocoa powder, or a sprinkle of finely chopped nuts add delightful texture and complement the deep chocolate flavor. A few mint leaves or delicate chocolate shavings can add elegance and a hint of freshness that makes every bite feel even more special.
Side Dishes
Pair this dessert with a lightly sweetened whipped cream or a scoop of vanilla bean ice cream to balance the intense chocolate. Fresh fruit like raspberries or strawberries offer a tangy contrast that enlivens the palate, making each forkful even more enjoyable.
Creative Ways to Present
Turn this cake into individual servings by using small glasses or ramekins to layer cake and mousse, topped with ganache for an elegant presentation. Alternatively, create a trifle with added layers of fruit and cookie crumbs for a playful twist. The versatility of this Chocolate Mousse Cake Recipe means you can always keep your dessert table exciting.
Make Ahead and Storage
Storing Leftovers
You can store leftover slices of Chocolate Mousse Cake Recipe in an airtight container in the refrigerator for up to 3 days. Keeping it chilled maintains the mousse’s airy texture and prevents the ganache from losing its glossy finish.
Freezing
If you want to enjoy this cake later, wrap it tightly in plastic wrap and aluminum foil before freezing. It can last up to one month frozen. Thaw it overnight in the refrigerator before serving to preserve texture and flavor.
Reheating
This cake is best enjoyed cold, so reheating isn’t recommended. If you want to soften the ganache slightly, let it rest at room temperature for about 15 minutes before serving to loosen up the ganache’s texture without sacrificing the mousse’s lightness.
FAQs
Can I use milk chocolate instead of semi-sweet chocolate?
Using milk chocolate will make the cake sweeter and less intense in chocolate flavor. If you prefer a sweeter dessert, it’s a fine substitution, though semi-sweet chocolate provides the classic rich taste for this recipe.
Is gelatin necessary for the mousse?
Gelatin helps stabilize the mousse and keeps it firm after chilling. Without it, the mousse may be softer and less structured, so it’s recommended for best results in this Chocolate Mousse Cake Recipe.
Can I make this cake gluten-free?
Absolutely! Replace the all-purpose flour with a gluten-free flour blend that measures cup for cup. Just ensure your cocoa powder and other ingredients are certified gluten-free as well.
How long does this cake take to set properly?
For the mousse layer, refrigerate for at least 2 hours to set before adding the ganache. After pouring the ganache, give it another hour to chill for a perfect finish.
Can I prepare parts of this cake in advance?
Yes! You can bake the cake base a day ahead and keep it wrapped tightly. The mousse can be made several hours ahead as well, making this Chocolate Mousse Cake Recipe a wonderful choice for entertaining.

Ingredients
Cake Base
- ½ cup all-purpose flour
- ⅓ cup unsweetened cocoa powder
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 2 large eggs
- ½ cup granulated sugar
- ¼ cup unsalted butter, melted
- 1 teaspoon vanilla extract
Chocolate Mousse
- 8 oz semi-sweet chocolate, chopped
- 1 ½ cups heavy cream, divided
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
Ganache
- ½ cup heavy cream
- 4 oz semi-sweet chocolate, finely chopped
Instructions
- Prepare the Cake Base: Preheat your oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan to ensure easy release. In a medium bowl, sift together the all-purpose flour, cocoa powder, baking powder, and salt to combine and remove lumps. In a separate bowl, whisk the eggs and granulated sugar until the mixture is light and fluffy, which gives the cake a good structure. Add the melted unsalted butter and vanilla extract, mixing gently. Fold in the dry ingredients carefully to keep the batter light. Pour the batter evenly into the prepared pan and bake for 12-15 minutes or until a toothpick inserted in the center comes out clean. Remove from oven and allow the cake to cool completely in the pan.
- Make the Chocolate Mousse: Begin by blooming the gelatin: sprinkle the gelatin over 1 tablespoon of water in a small bowl and let it sit for 5 minutes until it softens. Melt 8 oz of chopped semi-sweet chocolate together with ½ cup of heavy cream using a double boiler or microwave in short bursts, stirring frequently until completely smooth. Allow the chocolate mixture to cool slightly so it doesn’t curdle the cream. Warm the gelatin mixture in the microwave just enough to dissolve it fully, then stir into the melted chocolate. In a separate bowl, whip the remaining 1 cup of heavy cream to soft peaks. Gently fold the whipped cream into the chocolate mixture to create a light and airy mousse. Spread this mousse evenly over the cooled cake base. Refrigerate for 2 hours or until the mousse is fully set.
- Make the Ganache: Heat the remaining ½ cup of heavy cream in a saucepan just until it begins to simmer—do not boil. Immediately remove from heat and pour the hot cream over the 4 oz of finely chopped semi-sweet chocolate. Let sit for a minute to soften the chocolate, then stir until the ganache is smooth, shiny, and slightly thickened but still pourable. Allow the ganache to cool slightly if needed.
- Assemble the Cake: Pour the ganache evenly over the set mousse layer, smoothing the top carefully with a spatula. Refrigerate the cake for another hour to allow the ganache to set firmly. Before serving, run a warm knife around the edge of the springform pan to loosen the cake, then gently release the sides. Slice the cake with a sharp knife and serve chilled for the best texture and flavor.
Notes
- Ensure the cake base is completely cool before adding mousse to avoid melting the mousse.
- Use good quality semi-sweet chocolate for the best flavor experience.
- When folding whipped cream into chocolate, do so gently to maintain a light mousse texture.
- Chilling times are important for proper set and texture; avoid rushing the refrigeration steps.
- Run a warm knife between slices for cleaner cuts and to prevent cracking of layers.
