Ingredients You’ll Need
The magic behind this Chocolate Mousse Cake Recipe lies in its simplicity and quality ingredients. Each component plays an essential role, whether it’s giving the cake structure, the mousse its airy lightness, or the ganache its shiny finish.
- ½ cup all-purpose flour: Provides the perfect foundation for the cake layer, ensuring a tender crumb.
- ⅓ cup unsweetened cocoa powder: Adds deep chocolate flavor and rich color to the cake.
- ½ teaspoon baking powder: Gives the cake a gentle rise for lightness.
- ¼ teaspoon salt: Enhances all the chocolate flavors, balancing sweetness.
- 2 large eggs: Important for structure and moisture in the cake.
- ½ cup granulated sugar: Sweetens the cake and helps with that tender texture.
- ¼ cup unsalted butter, melted: Adds richness and moisture to the cake batter.
- 1 teaspoon vanilla extract: Brings subtle warmth and depth to the cake’s flavor.
- 8 oz semi-sweet chocolate, chopped: The hero of the mousse, melted for that creamy, chocolaty goodness.
- 1 ½ cups heavy cream, divided: Used for both the mousse’s airy texture and the ganache’s silky finish.
- 1 teaspoon unflavored gelatin: Stabilizes the mousse, ensuring it sets perfectly.
- 1 tablespoon water: Needed to bloom the gelatin before mixing it in.
- ½ cup heavy cream (for ganache): Intensifies the shiny, glossy topping.
- 4 oz semi-sweet chocolate, finely chopped: The secret to that smooth, luxurious ganache that crowns the cake.
How to Make Chocolate Mousse Cake Recipe
Step 1: Prepare the Cake Base
First thing’s first, preheat your oven to 350°F (175°C) and get your 9-inch springform pan greased and lined. In one bowl, sift together the flour, cocoa powder, baking powder, and salt—this ensures your cake base is perfectly smooth. In another bowl, whisk the eggs with sugar until the mixture is light and fluffy, building the cake’s light texture. Slowly add the melted butter and vanilla extract, then carefully fold in the dry ingredients to keep it airy. Pour the batter into the pan and bake for about 12-15 minutes until a toothpick comes out clean. Once baked, let it cool completely right there in the pan.
Step 2: Make the Chocolate Mousse
While the cake cools, it’s time to whip up the luscious chocolate mousse. Start by sprinkling the gelatin over water and letting it bloom for 5 minutes—that’s the key for a mousse that sets just right. Melt the chopped semi-sweet chocolate together with half a cup of cream over a double boiler or in a microwave, stirring gently until perfectly smooth. Let this mixture cool slightly, then warm the bloomed gelatin just enough to dissolve it and combine it with the chocolate. Meanwhile, whip the remaining 1 cup of cream to soft peaks—light and fluffy is what you want! Gently fold this whipped cream into the chocolate mixture, creating that dreamy mousse texture. Spread the mousse over the cooled cake base and pop it in the fridge for about 2 hours so it firms up beautifully.
Step 3: Make the Ganache
The final touch is a shiny ganache that adds a rich, silky finish to the cake. Heat the remaining ½ cup of heavy cream in a small saucepan until just simmering—watch carefully so it doesn’t boil over. Pour the hot cream over the finely chopped chocolate and stir continuously until you achieve a smooth, glossy mixture that’s thick enough to pour but will set nicely. Let it cool slightly before moving on.
Step 4: Assemble the Cake
Pour the ganache over the chilled mousse layer and spread it evenly, making sure every inch is covered with this glossy goodness. Refrigerate the whole cake for another hour to let everything set perfectly. When ready to serve, run a warm knife around the springform pan’s edge to loosen the cake for a clean release, then slice and serve cold for the best texture and flavor experience.
How to Serve Chocolate Mousse Cake Recipe
Garnishes
This cake is stunning on its own, but adding a few garnishes can elevate it even more. Fresh berries like raspberries or strawberries add a bright contrast and a juicy burst that pairs perfectly with rich chocolate. A dusting of cocoa powder or shaved chocolate curls also adds elegant texture and visual appeal. For a festive touch, sprinkle some crushed nuts or a pinch of edible gold dust.
Side Dishes
Consider serving your slice of Chocolate Mousse Cake Recipe alongside a scoop of vanilla bean ice cream to balance the richness with creamy coolness. A dollop of freshly whipped cream or a drizzle of berry coulis offers a delightful tartness and lightness. For a grown-up twist, a glass of port wine or a rich espresso can wonderfully complement the layered chocolate flavors.
Creative Ways to Present
Presentation can turn this dessert into the star of any occasion. Try serving individual mousse cakes in elegant clear glasses or jars for a modern look while showcasing the layers. You could also build mini versions using a muffin tin to offer bite-sized indulgences. Decorating the top with edible flowers or mint leaves adds a fresh, sophisticated touch. Experimenting with layered parfait-style portions might become a new favorite way to enjoy this recipe!
Make Ahead and Storage
Storing Leftovers
This Chocolate Mousse Cake Recipe keeps wonderfully refrigerated for up to 3 days. Store it tightly covered with plastic wrap or in an airtight container to prevent the mousse from absorbing any fridge odors and to maintain its moist texture. Always keep it chilled to preserve the mousse’s delicate structure.
Freezing
If you want to prepare this cake ahead of time, freezing is an option. Make sure the cake is fully set and cover it tightly with plastic wrap and foil to avoid freezer burn. It can be frozen for up to 2 weeks. When ready to enjoy, thaw it slowly overnight in the refrigerator for best texture and flavor.
Reheating
Since mousse cakes are best enjoyed chilled, reheating is not recommended. Bringing the cake to room temperature before serving can soften the ganache slightly for a melt-in-your-mouth sensation, but do avoid warming it up as it could ruin the mousse’s airy quality.
FAQs
Can I use dark chocolate instead of semi-sweet?
Absolutely! Dark chocolate can add a more intense, slightly bitter depth to the mousse and ganache, perfect if you prefer your dessert less sweet. Just be mindful to taste the melted chocolate before folding it in and adjust sugar levels if necessary.
Is gelatin necessary for the mousse?
Gelatin helps the mousse set firmly so it holds its shape when sliced. Without it, the mousse might be too soft or runny. If you prefer a vegetarian alternative, you can try agar-agar but be aware it behaves differently, so some experimentation might be needed.
Can I make this cake gluten-free?
Yes, simply substitute the all-purpose flour with a gluten-free blend suitable for baking. Make sure your cocoa powder and other ingredients are certified gluten-free as well. The texture might vary slightly, but the chocolate flavors will still shine.
How long does it take for the mousse to set?
The mousse needs at least 2 hours in the refrigerator to set properly. For best results, allow it a bit more time if possible. Rushing this step may cause the mousse to be too soft and not hold its shape when sliced.
Can I prepare parts of the cake in advance?
You can definitely bake the cake base a day ahead and keep it wrapped tightly at room temperature or refrigerated. The mousse and ganache can be made separately and assembled on the same day to keep everything fresh and vibrant.

Making this Chocolate Mousse Cake Recipe is not only a rewarding baking adventure but also a celebration of chocolate in all its glorious forms. With its tender cake base, silky mousse, and shiny ganache, it’s the perfect dessert to impress family, friends, or even just to treat yourself on any day.

Ingredients
For the 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
For the Chocolate Mousse
- 8 oz semi-sweet chocolate, chopped
- 1 ½ cups heavy cream, divided
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
For the 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 prevent sticking. In a medium bowl, sift together the flour, cocoa powder, baking powder, and salt to combine and aerate the dry ingredients. In a separate bowl, whisk together the eggs and sugar until the mixture becomes light and fluffy, incorporating air for a tender crumb. Add the melted butter and vanilla extract to the egg mixture, then gently fold in the dry ingredients until just combined. Pour the batter evenly into the prepared pan and bake for 12-15 minutes, or until a toothpick inserted comes out clean. Remove from oven and allow the cake to cool completely in the pan.
- Make the Chocolate Mousse: Sprinkle the gelatin over the tablespoon of water in a small bowl and let it bloom for 5 minutes to soften. Melt 8 oz of chopped semi-sweet chocolate with ½ cup of heavy cream using a double boiler or microwave, stirring until smooth. Allow the chocolate mixture to cool slightly. Microwave the bloomed gelatin briefly until dissolved, then stir it into the melted chocolate mixture. Whip the remaining 1 cup of heavy cream to soft peaks using a mixer, then gently fold this whipped cream into the chocolate mixture to create a light, airy mousse. Spread the mousse evenly over the cooled cake base in the pan, then refrigerate for 2 hours to allow it to set.
- Make the Ganache: Heat the remaining ½ cup of heavy cream in a saucepan over medium heat until it just begins to simmer; do not boil. Remove from heat immediately and pour the hot cream over the finely chopped 4 oz semi-sweet chocolate in a bowl. Stir gently until the mixture is smooth, glossy, and slightly cooled but still pourable.
- Assemble the Cake: Pour the prepared ganache evenly over the mousse layer, spreading with a spatula for a smooth finish. Refrigerate the cake for an additional hour to let the ganache set firmly. Before serving, run a warm knife around the edges of the cake to loosen it from the pan, release the springform ring, slice, and serve chilled for the best texture and flavor.
Notes
- Ensure the cake base is completely cool before adding the mousse to prevent melting.
- Use a double boiler or microwave in short bursts to melt the chocolate gently without burning.
- To get soft peaks for the whipped cream, avoid over-whipping which can cause the cream to separate.
- The gelatin is key for stabilizing the mousse, so do not skip this step.
- Store the cake refrigerated and consume within 2-3 days for optimal freshness.
