Ingredients You’ll Need
All the ingredients in this recipe are simple, yet each plays a crucial role in creating the perfect Chocolate Brownie Mousse Cake Recipe. From the richness of butter and chocolate to the fluffiness of whipped cream, every element adds depth in flavor, texture, or appearance.
- Unsalted butter (1/2 cup, melted): Adds moistness to the brownie base and enhances its rich flavor.
- Granulated sugar (1 cup plus 2 tablespoons): Sweetens both the brownie and mousse layers, balancing chocolate’s bitterness.
- Large eggs (2): Provide structure and richness to the brownie foundation.
- Vanilla extract (1 teaspoon plus 1 teaspoon): Offers a subtle warmth and enhances all chocolate flavors.
- Unsweetened cocoa powder (1/3 cup): Gives the brownie its deep chocolate taste and color.
- All-purpose flour (1/2 cup): Ensures the brownie has just the right tender crumb.
- Salt (1/4 teaspoon): Elevates and balances the sweetness in the recipe.
- Baking powder (1/4 teaspoon): Provides a slight lift to the brownie base without compromising density.
- Heavy whipping cream (2 cups total): Whipped cream forms the light, airy mousse and smooth topping.
- Semi-sweet chocolate (8 oz, chopped): The star ingredient for the creamy mousse layer.
- Powdered sugar (2 tablespoons): Sweetens and stabilizes the whipped cream topping.
- Chocolate shavings or cocoa powder (optional): Adds a decorative and flavorful finishing touch.
How to Make Chocolate Brownie Mousse Cake Recipe
Step 1: Prepare the Brownie Base
Begin by preheating your oven to 350°F (175°C) and lining the bottom of a 9-inch springform pan with parchment paper. This ensures easy removal later. In a medium bowl, whisk the melted butter, granulated sugar, eggs, and vanilla extract together until smooth and glossy. Gently sift in the cocoa powder, flour, salt, and baking powder, folding just until combined. Pour this luscious batter into your prepared pan and bake for about 20 to 25 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out with moist crumbs. Leaving it too dry can make the brownie base less inviting, so aim for that perfect fudgy texture. Let the brownie cool completely in the pan before moving on to the next step.
Step 2: Make the Chocolate Mousse
While the brownie cools, start on the sumptuous chocolate mousse. Heat half a cup of the heavy whipping cream in a saucepan over medium heat until it just begins to simmer—but don’t let it boil. Pour this hot cream over your chopped semi-sweet chocolate in a heatproof bowl. Let it sit for two minutes to melt the chocolate gently, then stir until you achieve a glossy, smooth ganache. Let this mixture cool down to room temperature so it won’t deflate the whipped cream. Meanwhile, whip the remaining one cup of heavy cream with 2 tablespoons of granulated sugar and 1 teaspoon of vanilla extract until soft peaks form. Now, carefully fold the whipped cream into the cooled chocolate ganache. This gentle folding keeps the mousse wonderfully airy, completing that dreamy texture.
Step 3: Assemble and Chill
Spread the luscious mousse evenly over your cooled brownie base while still in the springform pan. It’s important this layer is smooth and uniform to achieve a beautiful cake slice. Refrigerate the entire cake for at least four hours, allowing the mousse to set perfectly. This chilling step helps meld all the flavors and textures together, creating a cake that is as delicious as it looks.
Step 4: Prepare the Topping
Just before serving, whip the remaining half cup of heavy cream with 2 tablespoons of powdered sugar until soft peaks form. You can spread this lightly over the mousse or pipe it in elegant swirls. For a final flourish, dust the top with cocoa powder or sprinkle chocolate shavings for an irresistible, inviting look. Keep the cake chilled until you’re ready to serve this star-worthy delight.
How to Serve Chocolate Brownie Mousse Cake Recipe
Garnishes
The beauty of this cake is in the details. Garnish with delicate chocolate shavings or a light dusting of cocoa powder to add texture and visual appeal. If you want to experiment, a few fresh raspberries or a sprig of mint can add a refreshing contrast and brighten the flavors even further without overpowering the rich chocolate.
Side Dishes
This cake pairs wonderfully with fresh berries or a tangy fruit compote that cuts through the richness. A scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream also complements the texture and temperature contrast perfectly, making every bite an experience to remember.
Creative Ways to Present
For a festive look, slice your Chocolate Brownie Mousse Cake Recipe and serve it on elegant dessert plates with a drizzle of chocolate or caramel sauce. Layer individual servings in clear glasses or parfait dishes, showcasing each decadent layer beautifully—perfect for parties or intimate dinners. You can also try decorating with edible gold leaf or tiny crushed nuts for a little extra wow factor.
Make Ahead and Storage
Storing Leftovers
This cake keeps beautifully in the refrigerator for up to three days when covered tightly with plastic wrap or stored in an airtight container. The mousse layer stays creamy and the brownie base remains moist, so your leftovers will still taste fresh and indulgent whenever you revisit them.
Freezing
While this cake is best enjoyed fresh, you can freeze it for up to a month if needed. Wrap the whole cake (or individual slices) tightly in plastic wrap followed by aluminum foil to prevent freezer burn. Thaw in the refrigerator overnight before serving to preserve its texture and flavor.
Reheating
Since this is a chilled mousse cake, reheating is not recommended. The mousse can melt and lose its structure. Instead, simply allow refrigerated slices to come to room temperature for about 15 minutes before serving to enjoy the full depth of flavor and creaminess.
FAQs
Can I use dark chocolate instead of semi-sweet chocolate?
Absolutely! Using dark chocolate will give your mousse a richer and more intense chocolate flavor. Just make sure it’s good quality chocolate for the best results in your Chocolate Brownie Mousse Cake Recipe.
Is it necessary to use a springform pan?
Using a springform pan makes removing the cake easier and keeps the layers intact, but if you don’t have one, you can use a regular cake pan lined with parchment paper. Just be extra gentle when lifting the cake out.
Can I make this recipe gluten-free?
Yes! Simply substitute the all-purpose flour with your favorite gluten-free flour blend that measures cup for cup, and you’ll have a gluten-free version of the Chocolate Brownie Mousse Cake Recipe without sacrificing the texture or taste.
How long does the mousse need to chill for?
The mousse needs at least 4 hours to set properly, but chilling it overnight will give even better texture and flavor, helping the mousse firm up nicely on the brownie base.
Can I prepare parts of this cake ahead of time?
Definitely. The brownie base can be baked a day ahead and stored at room temperature. You can make the mousse and assemble the cake the day before serving, which actually helps the flavors marry beautifully.

Instructions
- Prepare the Brownie Base: Preheat your oven to 350°F (175°C) and line the bottom of a 9-inch springform pan with parchment paper.
