Ingredients
- 1 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk
- 6 ounces dark chocolate (70% cocoa), chopped
- 1 cup heavy cream
- 1/4 cup powdered sugar
- 1 teaspoon orange zest
- 1/4 cup chocolate shavings, for garnish
- Fresh orange slices, for garnish
How to Make Chocolate Mousse Cake
- Preheat your oven to 350°F (175°C). Grease and flour an 8-inch round cake pan.
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
- In a large bowl, cream the softened butter and granulated sugar until light and fluffy, about 3-4 minutes.
- Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
- Alternate adding the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined.
- Pour the batter into the prepared cake pan and smooth the top. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.
- While the cake cools, melt the dark chocolate in a heatproof bowl over simmering water, stirring until smooth. Remove from heat and let it cool slightly.
- In a separate bowl, whip the heavy cream and powdered sugar until soft peaks form.
- Gently fold the melted chocolate and orange zest into the whipped cream until fully combined, being careful not to deflate the mixture.
- Once the cake is completely cooled, slice it in half horizontally to create two layers.
- Spread half of the chocolate mousse on top of the bottom layer, then place the other layer on top. Cover the entire cake with the remaining mousse.
- Refrigerate for at least 2 hours to set before serving. Decorate with chocolate shavings and fresh orange slices just before serving.
Tips for the Best Results
- Make sure all ingredients are at room temperature for a smoother batter and mousse.
- Use high-quality dark chocolate for a richer flavor.
- Allow the cake to cool completely before assembling to prevent the mousse from melting.
- For a more intense orange flavor, add an additional teaspoon of orange zest to the mousse.
Easy Variations
- Swap the dark chocolate for milk chocolate for a sweeter version.
- Add a splash of orange liqueur to the mousse for an adult twist.
- Incorporate a layer of orange curd between the cake layers for extra citrus flavor.
What to Serve With It
- A scoop of vanilla ice cream to balance the richness.
- Fresh berries for a pop of color and tartness.
- A dollop of whipped cream for added creaminess.
- A cup of coffee or espresso to complement the chocolate flavors.
