- 8 oz dark chocolate: Choose good quality chocolate for the richest flavor and smoothest melt.
- 4 large eggs: Vital for creating a fluffy batter and binding the ingredients together.
- 1 cup granulated sugar: Adds sweetness while helping the eggs become light and airy.
- 1/2 cup unsalted butter: Adds moisture and a velvety texture without overpowering the chocolate.
- 1 tsp vanilla extract: A little warmth and background depth to complement the chocolate.
- 1/4 cup all-purpose flour: Provides just enough structure to hold the cake without making it heavy.
- 1/4 cup unsweetened cocoa powder: Boosts the chocolate intensity while lending a deep color.
- 1 cup whipped cream: Essential for delivering the luscious, airy mousse layer that elevates the cake.
How to Make Chocolate Mousse Cake Recipe
Step 1: Prepare Your Pans and Oven
Start by preheating your oven to 350°F (175°C). Greasing two 9-inch round cake pans and dusting them lightly with cocoa powder ensures that the cake layers won’t stick and adds a subtle chocolate hint to the edges. Prep here is key for clean layers and an easy release once baked.
Step 2: Melt the Chocolate and Butter
Gently melt the dark chocolate and unsalted butter together until silky smooth. Doing this slowly, either over a double boiler or in short bursts in the microwave, prevents scorching and guarantees that luscious foundation for your mousse cake.
Step 3: Whisk Eggs and Sugar
Whisk the eggs and granulated sugar vigorously until the mixture turns pale and fluffy—this step introduces air that will give your cake its tender crumb and light texture. It’s a workout but so worth the effort for that perfect rise.
Step 4: Combine Chocolate Mixture with Eggs
Fold the melted chocolate and butter carefully into the fluffy egg mixture. The folding technique protects the airiness you just worked hard to create, resulting in a batter that’s both rich and light—exactly what a great mousse cake needs.
Step 5: Incorporate Dry Ingredients
Sift together the all-purpose flour and cocoa powder to avoid lumps, then gently fold them into your chocolate batter. This step adds just enough structure to hold the cake together without making it dense or heavy.
Step 6: Bake and Cool
Divide the batter evenly between your prepared pans and bake for 25 to 30 minutes. Keep a close watch near the end; the cake should be set but still moist inside. Once out of the oven, cool the cakes completely on wire racks—cooling is essential before adding your mousse layer to prevent melting.
Step 7: Whip the Cream and Assemble
Whip fresh cream until you see soft peaks form—this is the luscious mousse layer that adds lightness and richness. Layer the whipped cream between the two cakes and spread it on top for a beautiful, inviting finish.
How to Serve Chocolate Mousse Cake Recipe
Garnishes
Garnishes are where you can really make this cake shine visually and add some texture contrast. Sprinkle shaved chocolate or cocoa powder on top or add fresh raspberries for a tart burst of flavor. A few mint leaves can brighten the plate and add a fresh aroma that complements the rich chocolate flavors.
Side Dishes
A scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream pairs beautifully, enhancing the creamy, rich qualities of the cake. For a more grown-up pairing, a glass of dessert wine or robust coffee provides a delightful flavor balance.
Creative Ways to Present
Get creative by serving individual slices with a drizzle of raspberry coulis or salted caramel sauce for an extra layer of decadence. Alternatively, plate the cake alongside fresh fruit salad for a refreshing counterpoint. Serving mini mousse cakes in clear glasses layered with chocolate cake bits offers a fun, elegant twist on the classic.
Make Ahead and Storage
Storing Leftovers
This Chocolate Mousse Cake Recipe actually benefits from resting in the fridge overnight, allowing the flavors to meld and the mousse to set perfectly. Store leftovers covered tightly with plastic wrap or in an airtight container to keep the cake moist and the mousse creamy for up to three days.
Freezing
You can freeze the cake layers before assembling, well wrapped in plastic and foil to protect from freezer burn, for up to a month. When ready to serve, thaw them in the refrigerator overnight before whipping your cream and assembling the cake fresh for best texture and flavor.
Reheating
Since this cake is best served chilled, reheating isn’t typically recommended. However, if you prefer slightly less chill, leave slices out at room temperature for 20 minutes before serving to let the chocolate soften just a touch.
FAQs
Can I use milk chocolate instead of dark chocolate?
Absolutely! Milk chocolate will create a sweeter and lighter mousse cake, though the flavor will be less intense. Make sure to adjust the sugar slightly to avoid the cake becoming overly sweet.
Is it necessary to bake the cake layers? Can I make a no-bake version?
Baking the cake layers gives the dessert structure and that classic texture. While some mousse cakes use a no-bake crust, this recipe relies on baked layers, so skipping this step would change the cake significantly.
How do I achieve soft peaks when whipping cream?
Chill the bowl and whisk before whipping, and start at medium speed. Soft peaks form when the cream holds its shape but the tips slightly fold over when you lift the whisk. Be careful not to overwhip or the cream will become grainy.
Can I make this cake vegan or dairy-free?
Substituting ingredients for a vegan version requires some tweaks, like using dairy-free chocolate, plant-based butter, and aquafaba for eggs. While possible, the results differ, and the texture won’t be exactly the same as the classic recipe.
What’s the best way to slice the mousse cake cleanly?
Use a sharp knife dipped in hot water and wiped dry before each cut. This warms the blade and reduces sticking, ensuring smooth, clean slices every time.

Ingredients
For the Cake:
- 8 oz dark chocolate
- 4 large eggs
- 1 cup granulated sugar
- 1/2 cup unsalted butter
- 1 tsp vanilla extract
- 1/4 cup all-purpose flour
- 1/4 cup unsweetened cocoa powder
For the Mousse Layer:
- 1 cup whipped cream
Instructions
- Prepare the pans: Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans thoroughly and dust them with cocoa powder to prevent sticking and add extra chocolate flavor.
- Melt chocolate and butter: In a double boiler or a heatproof bowl over simmering water, melt the dark chocolate and unsalted butter together until smooth and fully blended. Set aside to cool slightly.
- Whisk eggs and sugar: Using a mixer, whisk the eggs and granulated sugar vigorously until the mixture becomes pale, fluffy, and thickens, which helps incorporate air for a light texture.
- Combine wet ingredients: Gently fold the melted chocolate and butter mixture into the egg and sugar mixture, ensuring an even blend without deflating the batter.
- Add dry ingredients: Sift the all-purpose flour and unsweetened cocoa powder together to avoid lumps, then carefully fold them into the wet batter until fully incorporated and smooth.
- Bake the cakes: Divide the batter evenly between the prepared pans and bake in the preheated oven for 25 to 30 minutes. The cakes should be set but moist in the center. Once done, remove from oven and let cool completely on wire racks.
- Whip the cream: While the cakes are cooling, whip the fresh cream until soft peaks form, making the mousse layer light and airy.
- Assemble the cake: Place one cake layer on a serving plate, spread half of the whipped cream evenly on top, then place the second cake layer over it. Finish by spreading the remaining whipped cream on top of the cake. Chill briefly if desired before serving.
Notes
- Make sure the melted chocolate is not too hot when folding into the eggs to prevent cooking them prematurely.
- Whipping the eggs and sugar well is critical to achieving a light, airy cake.
- Use high-quality dark chocolate for the best flavor.
- You can substitute whipped cream with stabilized whipped cream if you want the mousse to hold longer.
- Chill the cake before serving for a firmer mousse texture.
