Ingredients

For the Cake:

• 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 (room temperature)
• 1 cup granulated sugar
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup whole milk
• 1/2 cup hot water (or brewed coffee for extra depth of flavor)

For the Dark Chocolate Mousse:

• 8 oz dark chocolate (70% cocoa or higher)
• 2 cups heavy whipping cream (chilled)
• 2 tablespoons powdered sugar
• 1 teaspoon vanilla extract
• 4 large egg yolks
• 2 tablespoons granulated sugar
• 1/4 cup water

For Garnish (Optional):

• Dark chocolate shavings
• Fresh berries (like raspberries or strawberries)
• Whipped cream

Instructions

1. Make the Chocolate Cake:

• Preheat your oven to 350°F (175°C). Grease and line a 9-inch round cake pan with parchment paper.
• In a bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
• In another bowl, cream the butter and sugar together until light and fluffy. Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract.
• Gradually add the dry ingredients to the wet ingredients, alternating with the milk, until everything is well combined. Stir in the hot water (or coffee) until smooth.
• Pour the batter into the prepared cake pan and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely in the pan before transferring it to a wire rack.

2. Prepare the Dark Chocolate Mousse:

• Melt the dark chocolate in a heatproof bowl set over simmering water (double boiler method), stirring occasionally until smooth. Let the chocolate cool slightly.
• In a small saucepan, combine the egg yolks, granulated sugar, and water. Cook over low heat, whisking constantly, until the mixture thickens and coats the back of a spoon (about 4-5 minutes). Remove from heat and whisk into the melted chocolate until smooth.
• In a separate bowl, whip the heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Gently fold the whipped cream into the chocolate mixture in batches, being careful not to deflate the mousse.

3. Assemble the Cake:

• Once the cake has cooled completely, place it on a serving plate or cake board. If necessary, trim the top to make it even.
• Spread the dark chocolate mousse evenly over the top and sides of the cake, creating a smooth layer. Use an offset spatula to get a clean finish.

4. Chill and Garnish:

• Refrigerate the cake for at least 2-3 hours (or overnight) to allow the mousse to set.
• Before serving, garnish with dark chocolate shavings, fresh berries, or a dollop of whipped cream.

Additional Tips

1. Use Quality Chocolate: Opt for high-quality dark chocolate (70% cocoa or higher) for the best flavor.
2. Chill Your Mixing Bowl: For the best whipped cream results, chill your mixing bowl and beaters before whipping.
3. Coffee Enhances Flavor: Adding brewed coffee to the cake batter enhances the chocolate flavor without making it taste like coffee.
4. Don’t Overmix: When folding the whipped cream into the chocolate mixture, be gentle to maintain the mousse’s light texture.
5. Serve Cold: This cake is best served chilled, as the mousse holds its shape better and the flavors meld beautifully.

Recipe Variations

• Add a Layer: For an even richer dessert, consider adding a layer of ganache between the cake and mousse.
• Fruit Variation: Incorporate a layer of fresh fruit (like cherries or raspberries) between the cake and mousse for a tart contrast.
• Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend to make this cake gluten-free.

• Alternative Mousse: Use white chocolate or milk chocolate instead of dark chocolate for a different flavor profile.
