Ingredients
Scale
Cake Base
- ½ cup all-purpose flour
- â…“ cup unsweetened cocoa powder
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 2 large eggs
- ½ cup granulated sugar
- ¼ cup unsalted butter, melted
- 1 teaspoon vanilla extract
Chocolate Mousse
- 8 oz semi-sweet chocolate, chopped
- 1 ½ cups heavy cream, divided
- 1 teaspoon unflavored gelatin
- 1 tablespoon water
Ganache
- ½ cup heavy cream
- 4 oz semi-sweet chocolate, finely chopped
Instructions
- Prepare the Cake Base: Preheat the oven to 350°F (175°C). Grease and line the bottom of a 9-inch springform pan. In a medium bowl, sift together the flour, cocoa powder, baking powder, and salt. In another bowl, whisk eggs and sugar until light and fluffy. Add melted butter and vanilla extract, then fold in the dry ingredients until just combined. Pour the batter into the prepared pan and bake for 12-15 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool completely in the pan.
- Make the Chocolate Mousse: Sprinkle the gelatin over water in a small bowl and let it bloom for 5 minutes. Melt the 8 oz chopped chocolate with ½ cup of heavy cream using a double boiler or microwave, stirring until smooth and uniform. Slightly cool the melted chocolate mixture. Microwave the gelatin mixture just to dissolve it fully, then stir it into the melted chocolate. Whip the remaining 1 cup of heavy cream to soft peaks, then gently fold the whipped cream into the chocolate mixture until well combined. Spread the mousse evenly over the cooled cake base and refrigerate for 2 hours to allow it to set.
- Make the Ganache: Heat the remaining ½ cup of heavy cream in a saucepan until it just begins to simmer. Remove from heat and pour the hot cream over the finely chopped 4 oz semi-sweet chocolate. Let it sit for a minute, then stir gently until the ganache is smooth, glossy, and slightly thickened but still pourable. Let it cool slightly before using.
- Assemble the Cake: Pour the ganache evenly over the set mousse layer and spread gently to cover the surface. Refrigerate the cake for an additional hour to allow the ganache to set fully. Before serving, run a warm knife around the edges of the cake to loosen it from the pan, then carefully remove the springform ring. Slice and serve chilled for the best texture and flavor experience.
Notes
- Ensure the gelatin is fully dissolved to avoid lumps in the mousse.
- Use a sharp, warm knife to slice the cake cleanly.
- Store leftovers covered in the refrigerator and consume within 3 days.
- For a richer mousse, use higher quality chocolate with at least 60% cocoa content.
- Allow the cake to cool completely before applying mousse to prevent melting.
