This Chocolate Mousse Cake Recipe is the kind of dessert that makes you close your eyes and savor every single morsel. It’s rich, it’s fudgy, and it’s unapologetically chocolate.

INGREDIENTS You Need for This:

All the ingredients needed to make a chocolate mousse cake

1 cup (2 sticks) unsalted butter, softened. Don’t skimp – real butter is the key to that melt-in-your-mouth texture in this Chocolate Mousse Cake Recipe.
2 cups granulated sugar. This balances the intense chocolate and creates the perfect sweetness.
4 large eggs. These bind everything together, giving the cake its structure.
1 teaspoon vanilla extract. A touch of vanilla enhances all the other flavors.
1 cup all-purpose flour. This gives the cake a light, tender crumb. I tried a flourless chocolate mousse cake recipe, and while good, the texture was just not the same.
¾ cup unsweetened cocoa powder. Use a high-quality cocoa powder for the best chocolate flavor.
1 teaspoon baking soda. This gives the cake a little lift.
½ teaspoon baking powder. Adds another layer of leavening for a perfect rise.
½ teaspoon salt. Balances the sweetness and brings out the chocolate flavor.
1 cup buttermilk. This adds moisture and tanginess to the cake.
6 ounces bittersweet chocolate, chopped. This is the base of the mousse.
1 ½ cups heavy cream. For that luscious, airy mousse texture.
¼ cup powdered sugar. Sweetens the mousse without making it grainy.

The secret to an epic Chocolate Mousse Cake Recipe is using REAL bittersweet chocolate. Don’t even THINK about using chocolate chips. You’ll find the best cocoa powder for this Chocolate Mousse Cake Recipe at your local specialty store. Splurge on the bittersweet chocolate ingredient – trust me, you will taste the difference!

STEP-BY-STEP INSTRUCTIONS:

Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan. Don’t skip this step – nobody wants a cake that sticks! This Chocolate Mousse Cake Recipe is delicate.
In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the vanilla. Pro tip for Chocolate Mousse Cake Recipe perfection: make sure your butter is truly softened, not melted.
In a separate bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Don’t overmix – this will make your cake tough.
Pour the batter into the prepared cake pan and bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. In my kitchen, this Chocolate Mousse Cake Recipe takes exactly 32 minutes. Your Chocolate Mousse Cake Recipe should smell intensely chocolatey and feel springy to the touch.
Let the cake cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. While the cake is cooling, prepare the mousse. This is where your Chocolate Mousse Cake Recipe transforms into pure magic.
To make the mousse, melt the bittersweet chocolate in a double boiler or in the microwave in 30-second intervals, stirring until smooth. Let it cool slightly. This part can be tricky, so be patient and stir frequently to avoid burning the chocolate.
In a large bowl, whip the heavy cream with the powdered sugar until stiff peaks form. Gently fold in the cooled melted chocolate. Don’t deflate the cream – this is what makes the mousse light and airy.
Once the cake is completely cool, slice it in half horizontally. Spread the chocolate mousse evenly over the bottom layer of the cake, then top with the other cake layer. Here’s where most people mess up their Chocolate Mousse Cake Recipe – they try to assemble the cake while it’s still warm. Not you, though!
Refrigerate the cake for at least 2 hours before serving. This allows the mousse to set and the flavors to meld together. While your Chocolate Mousse Cake Recipe is working its magic, grab your camera – this is Instagram gold!

PRESENTATION:

People absolutely lose their minds when I serve this Chocolate Mousse Cake Recipe at dinner parties. Dust the top of the cake with cocoa powder or powdered sugar for a simple, elegant look. A few fresh raspberries add a pop of color and a burst of tartness that complements the rich chocolate.

This Chocolate Mousse Cake Recipe absolutely slays at dinner parties! Consider serving it with a scoop of vanilla ice cream or a dollop of whipped cream. For a truly decadent experience, pair it with a glass of port wine.

Leftovers? Crumble the cake and mousse into parfaits with layers of whipped cream and berries. Or, use it as a base for chocolate trifle. You could even try a dark chocolate mousse cake by using dark chocolate in the mousse.

FAQs:

Can I make this Chocolate Mousse Cake Recipe spicier?
Absolutely! A pinch of cayenne pepper in the cake batter or a dash of chili powder in the mousse will add a subtle kick that complements the chocolate beautifully. I’ve even infused the heavy cream with a cinnamon stick for a warm, spicy note.
What if I don’t have buttermilk for my Chocolate Mousse Cake Recipe?
No problem! You can make a quick buttermilk substitute by adding 1 tablespoon of white vinegar or lemon juice to a cup of milk. Let it sit for 5 minutes, and you’re good to go. I’ve used this trick countless times when I’m out of buttermilk.
How do I know when my Chocolate Mousse Cake Recipe is perfectly done?
The wooden skewer test is your best friend! If it comes out clean with just a few moist crumbs, your cake is ready. Also, look for the edges of the cake to pull away slightly from the sides of the pan.
Can I make this Chocolate Mousse Cake Recipe ahead of time?
Yes, you can! In fact, I recommend it. The flavors deepen and meld together beautifully after a day or two in the fridge. Just be sure to store it in an airtight container to prevent it from drying out.
What if my mousse is too runny?
This can happen if your chocolate is too warm when you fold it into the whipped cream. Try chilling the mousse in the fridge for 30 minutes to an hour to help it firm up. If it’s still too runny, you can gently fold in a tablespoon or two of powdered sugar.
Can I freeze this Chocolate Mousse Cake Recipe?
Yes, you can freeze the cake layers separately. Wrap them tightly in plastic wrap and then in foil. However, I don’t recommend freezing the assembled cake with the mousse, as the mousse can become icy and lose its texture.
I’m allergic to gluten. Is there a way to make a flourless chocolate mousse cake recipe?
I actually tried this Flourless Chocolate Mousse Cake Recipe once, and while the flavor was great, I really missed the texture that the flour provided!

Instructions

Make the Cake: Preheat oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
In a large bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt.
In a separate bowl, combine sugar, oil, vanilla, buttermilk, and eggs. Beat until smooth.
Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
Stir in boiling water until the batter is thin.
Pour batter into the prepared pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Let cool in the pan for 10 minutes, then invert onto a wire rack to cool completely.
Make the Mousse: Melt chocolate and butter together in a heatproof bowl set over a saucepan of simmering water, stirring until smooth. Remove from heat and let cool slightly.
In a small saucepan, combine heavy cream and heat until simmering.
In a mixing bowl, whisk egg yolks and sugar until pale and thick. Gradually pour hot cream into the egg yolk mixture, whisking constantly.
Return the mixture to the saucepan and cook over low heat, stirring constantly, until the mixture thickens slightly and coats the back of a spoon.
Pour the custard over the melted chocolate and stir until smooth. Let cool slightly.
In a clean, dry bowl, beat egg whites until stiff peaks form. Gently fold the egg whites into the chocolate mixture.
In another bowl, whip chilled heavy cream until stiff peaks form. Gently fold the whipped cream into the chocolate mixture.
Assemble the Cake: Cut the cooled cake in half horizontally.
Place one layer on a serving plate and spread with half of the chocolate mousse. Top with the second cake layer and spread with the remaining mousse.
Refrigerate for at least 2 hours, or until the mousse is set.
