Ingredients You’ll Need
The beauty of this Chocolate Mousse Cake Recipe is in its simplicity. Each ingredient plays a crucial role—from the tender, cocoa-rich cake base to the silky mousse and airy whipped cream topping, every element combines to create a perfectly balanced dessert.
- All-purpose flour: Provides structure to the cake, ensuring it’s soft yet sturdy enough to hold the mousse.
- Sugar: Sweetens the cake and mousse, balancing the bittersweet chocolate flavors.
- Unsweetened cocoa powder: Infuses a deep, vivid chocolate flavor into the cake base.
- Baking soda and baking powder: Work together to give the cake a light and airy crumb.
- Salt: Enhances the chocolate taste and balances the sweetness.
- Egg: Adds moisture and helps bind the cake ingredients for a tender texture.
- Whole milk: Adds richness and keeps the cake moist.
- Vegetable oil: Keeps the cake tender and moist without overpowering the flavor.
- Pure vanilla extract: Adds a subtle, fragrant sweetness that complements chocolate beautifully.
- Boiling water: Activates the cocoa powder for a stronger chocolate taste and thins the batter for even baking.
- Heavy cream: Used both for the luscious mousse and the whipped cream topping for that buttery richness.
- Semisweet chocolate: Melts into the mousse, creating creamy chocolate decadence.
- Unsalted butter: Adds silkiness to the mousse and enriches the texture.
- Sugar and powdered sugar: Essential for sweetness in mousse and whipped cream without graininess.
- Vanilla extract and pinch of salt (for mousse and topping): Enhance the flavors, making every bite irresistible.
- Chocolate shavings: A final decorative touch that brings extra chocolatey charm.
How to Make Chocolate Mousse Cake Recipe
Step 1: Prepare the Cake Base
Start by preheating your oven to 350°F (175°C) and greasing an 8-inch cake pan to ensure your cake releases beautifully. In a large bowl, combine all dry ingredients: flour, sugar, cocoa powder, baking soda, baking powder, and salt. This mix forms the foundation of the cake’s rich flavor and texture. Next, stir in the wet ingredients—egg, milk, vegetable oil, and vanilla extract—until everything blends smoothly. Pour in boiling water last and mix carefully; this step intensifies the chocolate flavor and yields a thin batter that bakes into a moist, tender cake. Pour the batter into your prepared pan and bake for 30 to 35 minutes until a toothpick inserted in the center comes out clean. Let the cake cool completely before moving on to the mousse layer.
Step 2: Make the Chocolate Mousse
While your cake cools, begin creating the decadent mousse. Warm one cup of heavy cream until it just starts to simmer, then pour it over chopped semisweet chocolate and unsalted butter in a bowl. Let it sit for a couple of minutes to melt smooth, then whisk until perfectly silky. Chill the mixture until it reaches room temperature—this helps with folding in the whipped cream smoothly. In a separate bowl, whip the remaining cream with sugar, vanilla extract, and a pinch of salt until stiff peaks form. Gently fold the whipped cream into your chocolate mixture, blending carefully to maintain airiness and create that luscious mousse texture.
Step 3: Assemble the Cake
Once your cake base is cool, spread the silky chocolate mousse evenly over the top. This rich layer is the star of your Chocolate Mousse Cake Recipe, offering an exquisite contrast to the denser cake beneath. Refrigerate the cake to set the mousse firmly, which usually takes a few hours and ensures that every slice holds its beautiful shape.
Step 4: Add the Whipped Cream Topping and Garnish
For the final flourish, whip together chilled heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Spread this delightful topping gently over the chilled mousse layer, creating a light, creamy cap atop your luxuriously rich dessert. Sprinkle with chocolate shavings for a touch of elegance and an extra burst of chocolate in every bite. Serve chilled for the best experience.
How to Serve Chocolate Mousse Cake Recipe
Garnishes
Adding simple garnishes like chocolate shavings elevates the presentation and intensifies the chocolate theme. Fresh berries such as raspberries or strawberries also complement the richness of the cake by adding a pop of color and a hint of tartness, balancing the sweetness beautifully.
Side Dishes
This cake pairs wonderfully with light, fresh sides to offset its richness. A crisp mint tea or a fresh fruit salad brightens the palate, while a scoop of vanilla ice cream adds an extra dimension of indulgence that everyone will love.
Creative Ways to Present
Consider serving individual slices on pretty dessert plates drizzled with raspberry coulis or caramel sauce for an elegant touch. For special occasions, top each slice with a dollop of whipped cream and an edible flower to impress your guests with minimal effort.
Make Ahead and Storage
Storing Leftovers
Store your leftover Chocolate Mousse Cake Recipe covered tightly with plastic wrap or in an airtight container in the refrigerator. It will stay fresh and delicious for up to 3 days, letting you savor every bite without worry.
Freezing
You can freeze the cake by wrapping it securely in plastic wrap and then aluminum foil to prevent freezer burn. When ready to enjoy, thaw it in the refrigerator overnight to preserve the mousse’s creamy texture. Freeze for up to 1 month for best results.
Reheating
This dessert is best enjoyed chilled, so there’s no need to reheat. If you prefer a slightly softer texture, let the cake sit at room temperature for about 20 minutes before serving to take the chill off gently.
FAQs
Can I use dark chocolate instead of semisweet for the mousse?
Absolutely! Dark chocolate will give a more intense, slightly bitter edge to the mousse, perfect if you prefer a less sweet, richer chocolate flavor.
Is it necessary to use boiling water in the cake batter?
Yes, boiling water helps bloom the cocoa powder, enhancing the chocolate flavor and giving the batter the perfect consistency for a moist cake base.
Can I substitute heavy cream with something else?
Heavy cream is essential for the mousse’s texture and the whipped topping’s stability, so substitutions might compromise the final result. For dairy-free options, coconut cream may work but will alter flavor and texture.
How long can the cake sit out before serving?
This cake should be kept refrigerated until serving because of the mousse and whipped cream layers. Leaving it out at room temperature for more than 2 hours is not recommended for food safety.
Can this cake be made in advance?
Yes! This Chocolate Mousse Cake Recipe actually benefits from making it a day ahead because chilling allows the mousse to set perfectly and the flavors to meld beautifully.

- 1/2 cup unsweetened cocoa powder
- 3/4 tsp baking soda
- 3/4 tsp baking powder
- 1/4 tsp salt

- 1/2 cup boiling water
Mousse:
- 1 1/2 cups heavy cream (divided)
- 12 oz semisweet chocolate, chopped
- 3 tbsp unsalted butter
- 2 tbsp sugar
- 2 tsp vanilla extract
- Pinch of salt
Whipped Cream Topping:
- 1 cup heavy cream, chilled
- 2 tbsp powdered sugar
- 1/2 tsp vanilla extract
Garnish:
- Chocolate shavings
Instructions
- Prepare the Cake Base: Preheat your oven to 350°F (175°C). Grease and flour an 8-inch cake pan to prevent sticking. In a large bowl, combine the flour, sugar, cocoa powder, baking soda, baking powder, and salt. Add the egg, whole milk, vegetable oil, and vanilla extract, and beat the mixture until smooth and well combined. Carefully stir in the boiling water last; the batter will be thin. Pour the batter into the prepared pan.
- Bake the Cake Base: Place the cake pan in the preheated oven and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Remove from the oven and allow the cake to cool completely in the pan on a wire rack.
- Make the Chocolate Mousse: Heat 1 cup of heavy cream in a saucepan until it just begins to simmer. Pour the hot cream over the chopped semisweet chocolate and butter placed in a heatproof bowl. Let it sit undisturbed for 2 minutes to melt the chocolate, then whisk vigorously until the mixture becomes smooth and glossy. Allow this chocolate mixture to chill until it reaches room temperature.
- Whip the Cream for Mousse: In a separate chilled bowl, beat the remaining 1/2 cup heavy cream with the sugar, vanilla extract, and a pinch of salt until stiff peaks form. Gently fold this whipped cream into the cooled chocolate mixture, being careful not to deflate it, to create a light and fluffy mousse.
- Assemble the Cake: Once the cake base has fully cooled, spread the prepared mousse evenly over the top. Place the cake in the refrigerator and chill until the mousse sets firmly, at least 2 hours.
- Prepare the Whipped Cream Topping: In a cold bowl, beat the chilled 1 cup heavy cream with powdered sugar and vanilla extract until stiff peaks form. Spread this whipped cream layer gently over the chilled mousse layer.
- Garnish and Serve: Decorate the top of the cake with elegant chocolate shavings. Keep the cake refrigerated until ready to serve to maintain the mousse and whipped cream stability.
Notes
- For best results, chill your mixing bowls and beaters before whipping cream to help it whip faster and hold shape better.
- Use high-quality semisweet chocolate for a richer mousse flavor.
- The boiling water added to the cake batter helps enhance the cocoa flavor and keeps the cake moist.
- The cake should be fully cooled before adding mousse to prevent melting or separating.
- Store the cake refrigerated and consume within 2-3 days for optimal freshness.
