Ingredients
- 6 ounces unsweetened chocolate
- ½ cup unsalted butter
- 1 cup granulated sugar
- 3 large eggs
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 3 tablespoons cocoa powder
- ¾ teaspoon gelatin powder
- 6 ounces semisweet chocolate
- 1½ cups heavy cream (cold)
- 2 tablespoons granulated sugar
- ¾ cups heavy cream
- 1 tablespoon unsalted butter
- 9 ounces semisweet chocolate
Instructions
- Step 1: Preheat the oven to 350°F (175°C). Melt the unsweetened chocolate and butter together in a double boiler until smooth. Set aside to cool.
- Step 2: In a mixing bowl, beat the sugar and eggs until the mixture is thick and pale. Stir in the vanilla extract and the cooled melted chocolate mixture.
- Step 3: Sift together the flour and cocoa powder, then gently fold them into the chocolate mixture until just combined. Pour the batter into a greased springform pan and bake for 35 minutes. Allow the cake to cool completely.
- Step 4: Bloom the gelatin powder in a small amount of water. Melt 6 ounces of semisweet chocolate. Whip 1½ cups cold heavy cream with 2 tablespoons sugar until soft peaks form. Gently combine the melted chocolate, gelatin, and whipped cream to create the mousse.
- Step 5: Pour half of the mousse over the cooled cake and chill for 30 minutes. Then, add the remaining mousse layer and refrigerate for at least two hours until fully set.
- Step 6: For the ganache, heat ¾ cup heavy cream and 1 tablespoon butter until hot but not boiling. Pour over 9 ounces chopped semisweet chocolate and stir until melted and smooth. Pour the ganache over the set mousse layer just before serving.
Tips & Variations
- Use high-quality chocolate for the richest flavor and smoothest texture in each layer.
- For a festive twist, add a splash of coffee or orange liqueur to the mousse mixture.
- If you don’t have a springform pan, a regular cake pan lined with parchment paper will work, but be careful when removing the cake.
- Chill the heavy cream thoroughly before whipping to help it reach the perfect soft peak consistency.
Storage
Store the Triple Chocolate Mousse Cake in the refrigerator, covered tightly with plastic wrap or an airtight lid. It will keep well for up to 3 days. To serve, you can let it sit at room temperature for 10–15 minutes for a softer texture. Do not freeze, as the mousse and ganache may separate upon thawing.
How to Serve
Serve this delicious recipe with your favorite sides.
FAQs
Can I make this cake in advance?
Yes, the cake can be assembled a day ahead and stored in the refrigerator, which actually allows the mousse layers to set fully and improves the texture and flavor.
What can I substitute for gelatin?
If you prefer a vegetarian option, agar-agar can be used as a substitute. Follow the package instructions for equivalent amounts and preparation methods.

Description
This decadent Triple Chocolate Mousse Cake combines layers of rich unsweetened chocolate cake with smooth, airy chocolate mousse and a glossy ganache topping. Perfect for chocolate lovers, this dessert offers a luxurious texture and intense chocolate flavor with each bite.
Ingredients
Cake
- 6 ounces unsweetened chocolate
- ½ cup unsalted butter
- 1 cup granulated sugar
- 3 large eggs
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 3 tablespoons cocoa powder
- ¾ teaspoon gelatin powder
Mousse
- 6 ounces semisweet chocolate
- 1 ½ cups heavy cream (cold)
- 2 tablespoons granulated sugar
Ganache
- ¾ cups heavy cream
- 1 tablespoon unsalted butter
- 9 ounces semisweet chocolate
Instructions
- Prepare the Cake Base: Preheat your oven to 350°F (175°C). Using a double boiler, melt the unsweetened chocolate and butter together until smooth. Allow the mixture to cool to avoid cooking the eggs in the next step.
- Mix Wet Ingredients: In a large bowl, beat the granulated sugar and eggs until the mixture becomes thick and creamy. Stir in the vanilla extract followed by the cooled melted chocolate and butter blend until fully incorporated.
- Combine Dry Ingredients and Bake: Sift together the all-purpose flour and cocoa powder. Gently fold these dry ingredients into the wet chocolate mixture until just combined, ensuring not to overmix. Pour the batter into a greased springform pan and bake for 35 minutes until set. Allow the cake to cool completely before proceeding.
- Prepare the Mousse: Bloom the gelatin powder in a small amount of water as per package instructions. Melt the 6 ounces of semisweet chocolate separately. Whip the 1 ½ cups of cold heavy cream with 2 tablespoons of granulated sugar until soft peaks form. Gently fold the whipped cream and melted chocolate together, then incorporate the bloomed gelatin until fully combined to create the mousse.
- Assemble the Mousse Layers: Spread half of the prepared mousse evenly over the cooled cake layer. Chill the cake with mousse in the refrigerator for 30 minutes to set. Then, add the remaining mousse on top and chill for at least two hours, or until fully firm.
- Make and Add the Ganache: Heat ¾ cups heavy cream and 1 tablespoon unsalted butter together until hot but not boiling. Pour this mixture over the 9 ounces chopped semisweet chocolate and stir gently until the chocolate is completely melted and the ganache is smooth. Pour the ganache evenly over the set mousse layer before serving.
Notes
- Be careful not to overmix the cake batter to keep it tender.
- Ensure the cake is completely cool before adding mousse to prevent melting.
- Chilling times are essential for mousse to set properly; don’t rush them.
- Use high-quality chocolate for the best flavor results.
- If gelatin is unavailable, you can substitute with agar-agar but adjust quantities accordingly.
