How to make Chocolate Mousse Cake
Ingredients:
- 1 cup all-purpose flour
- 1 cup granulated sugar
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon salt
- 1/2 cup vegetable oil
- 1/2 cup buttermilk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup boiling water
- 2 cups heavy cream
- 8 ounces semisweet chocolate, chopped (for mousse)
- 1/4 cup granulated sugar (for mousse)
- 1 teaspoon vanilla extract (for mousse)
- 1 cup heavy cream (for ganache)
- 8 ounces semisweet chocolate, chopped (for ganache)
Directions:
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large bowl, combine flour, sugar, cocoa powder, baking soda, baking powder, and salt. Whisk and set aside.
- In another bowl, whisk together vegetable oil, buttermilk, eggs, and vanilla extract until smooth. Gradually add to the dry mixture and mix until just combined.
- Slowly add boiling water, stirring gently until smooth.
- Divide batter between prepared pans. Bake for 25-30 minutes until a toothpick comes out clean. Cool in pans for 10 minutes before transferring to a wire rack.
- For the mousse, heat 1/2 cup of heavy cream until steaming. Pour over chopped chocolate, let sit for 5 minutes, then whisk until smooth.
- Whip remaining cream with sugar and vanilla until soft peaks form. Fold in chocolate mixture until well combined. Refrigerate for at least 1 hour.
- For the ganache, heat heavy cream until it simmers. Pour over chopped chocolate, let sit, then stir until smooth.
- Once cakes are cool, place one layer on a serving plate. Spread with chocolate mousse, add the second layer, and cover with remaining mousse.
- Pour ganache over the cake, allowing it to drip down the sides. Chill for at least 2 hours before serving.
How to serve Chocolate Mousse Cake
Serve the Chocolate Mousse Cake chilled. You can slice it into wedges and add a dollop of whipped cream on the side for extra creaminess. Fresh berries, like raspberries or strawberries, make a great garnish that adds a touch of freshness and color to the plate.
How to store Chocolate Mousse Cake
Store leftover Chocolate Mousse Cake in an airtight container in the refrigerator. It should stay fresh for about 3-4 days. If you want to keep it longer, you can freeze the cake without the ganache. Wrap it tightly in plastic wrap and store it in the freezer for up to 2 months. Just remember to let it thaw in the fridge before serving.
Tips to make Chocolate Mousse Cake
- Make sure your eggs and buttermilk are at room temperature; this helps create a better batter.
- Don’t skip the chilling time for the mousse; it helps the mousse firm up properly.
- Be gentle when folding the whipped cream into the chocolate mixture; you want to keep the airiness for a light mousse.
Variation
If you want to add different flavors, try incorporating orange zest for a citrus twist or a splash of espresso for a mocha flavor in the ganache or mousse.
