Incredible Chocolate Mousse Cake Recipe
Introduction
This Incredible Chocolate Mousse Cake is a decadent dessert that combines rich chocolate cake layers with a light, creamy mousse. Perfect for special occasions or when you crave an indulgent treat, it balances dense chocolate flavor with airy texture.

Ingredients
- 7 oz dark chocolate (70% cocoa)
- 1/2 cup unsalted butter
- 3/4 cup granulated sugar
- 4 large eggs
- 1 cup all-purpose flour
- 1/3 cup unsweetened cocoa powder
- 1 cup heavy cream
Instructions
- Step 1: Preheat your oven to 350°F (175°C) and grease two round cake pans.
- Step 2: Melt the dark chocolate and butter together in a double boiler until smooth.
- Step 3: In a bowl, whisk the sugar and eggs until pale and slightly thickened; then gently fold in the melted chocolate mixture.
- Step 4: Sift the flour and cocoa powder into the bowl and fold gently until the batter is combined.
- Step 5: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Step 6: Let the cakes cool completely while whipping the heavy cream to stiff peaks; fold the whipped cream into any remaining melted chocolate to create the mousse.
- Step 7: To assemble, spread half of the mousse over one cake layer, top with the second cake layer, and cover with the remaining mousse. Refrigerate for at least two hours before serving for best texture.
Tips & Variations
- For a richer mousse, use French-style heavy cream with higher fat content.
- Try adding a splash of coffee or espresso to the melted chocolate for enhanced depth of flavor.
- Use fresh berries or a raspberry sauce as a topping to add a bright contrast to the rich chocolate.
Storage
Store the cake covered in the refrigerator for up to 3 days. To serve, let it sit at room temperature for 10-15 minutes to soften slightly. The cake can also be frozen for up to a month; thaw overnight in the refrigerator before serving.

FAQs
Can I use milk chocolate instead of dark chocolate?
Dark chocolate is recommended for its rich flavor and firmness. Milk chocolate can be used but will result in a sweeter, softer cake and mousse.
Is it necessary to use a double boiler for melting chocolate?
Using a double boiler helps melt the chocolate gently without burning. If you don’t have one, melt the chocolate in short bursts in the microwave, stirring frequently.

Ingredients
Cake
- 7 oz dark chocolate (70% cocoa)
- 1/2 cup unsalted butter
- 3/4 cup granulated sugar
- 4 large eggs
- 1 cup all-purpose flour
- 1/3 cup unsweetened cocoa powder
Mousse
- 1 cup heavy cream
- Remaining melted dark chocolate from cake preparation
Instructions
- Preheat and Prepare Pans: Preheat your oven to 350°F (175°C) and grease two round cake pans to ensure the cakes do not stick during baking.
- Melt Chocolate and Butter: Melt the dark chocolate and unsalted butter together using a double boiler until the mixture is smooth and completely combined.
- Whisk Sugar and Eggs: In a separate bowl, whisk the granulated sugar and eggs until the mixture is pale and fluffy, helping to incorporate air for a lighter texture.
- Combine Mixtures: Gently fold the melted chocolate and butter mixture into the sugar and eggs mixture, combining them carefully to maintain airiness.
- Add Dry Ingredients: Sift the all-purpose flour and unsweetened cocoa powder into the wet ingredients and fold gently until just combined, avoiding overmixing.
- Bake the Cake: Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely on a wire rack.
- Prepare the Mousse: Whip the heavy cream to stiff peaks, then gently fold it into the remaining melted dark chocolate to create a smooth, airy mousse.
- Assemble the Cake: Place one cake layer on a serving plate, spread half of the mousse evenly over it. Top with the second cake layer and finish by spreading the remaining mousse on top. Refrigerate the assembled cake for at least two hours to set before serving.
Notes
- Use high-quality dark chocolate (at least 70% cocoa) for the best flavor and texture.
- Ensure cake layers are fully cooled before adding the mousse to prevent melting.
- For a firmer mousse layer, refrigerate the mousse mixture slightly before folding in whipped cream.
- This cake is best served chilled and can be stored in the refrigerator for up to 3 days.
