Ingredients:
For the Cake:
- 1 cup all-purpose flour
- 3/4 cup cocoa powder (unsweetened)
- 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 hot water
- 1/4 cup brewed coffee (strong)
For the Mocha Mousse:
- 8 oz dark chocolate (about 70% cocoa)
- 2 teaspoons instant coffee granules
- 1/4 cup hot water
- 1 1/4 cups heavy cream (divided)
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
For the Garnish (Optional):
- Chocolate shavings or curls
- Fresh coffee beans or edible gold leaf
Equipment:
- 9-inch round cake pan (or any other shape you prefer)
- Mixing bowls
- Electric mixer or whisk
- Rubber spatula
- Saucepan
- Double boiler or microwave-safe bowl for melting chocolate
Instructions:
1. Prepare the Cake Base:
- Preheat your oven to 350°F (175°C). Grease and flour your 9-inch round cake pan, or line it with parchment paper.
- In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
- In a separate bowl, cream the butter and sugar using an electric mixer until light and fluffy (about 3-4 minutes).
- Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
- Slowly add the dry ingredients to the wet mixture, alternating with the hot water and brewed coffee. Begin and end with the dry ingredients.
- Pour the batter into the prepared cake pan and smooth the top with a spatula.
- 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, then remove it and place it on a wire rack to cool completely.
2. Make the Mocha Mousse:
- Start by melting the dark chocolate. You can do this using a double boiler or by microwaving the chocolate in short bursts, stirring in between. Once melted, set aside to cool slightly.
- Dissolve the instant coffee granules in hot water. Stir the coffee mixture into the melted chocolate until smooth and well combined.
- In a separate bowl, whip 1 cup of the heavy cream with powdered sugar and vanilla extract until stiff peaks form.
- Gently fold the whipped cream into the cooled chocolate-coffee mixture. Be careful not to deflate the mousse.
- In another bowl, whip the remaining 1/4 cup of heavy cream until stiff peaks form. Fold this into the chocolate mixture as well.
3. Assemble the Cake:
- If your cake has a domed top, slice it off to create an even surface.
- Place the cooled cake onto a serving platter or cake stand. You can use a ring mold around the cake to prevent the mousse from spilling over the sides.
- Spread the mocha mousse over the cake, smoothing it into an even layer. Ensure the mousse covers the entire top of the cake, and create a slightly rounded mound if desired.
- Refrigerate the cake for at least 4 hours, or until the mousse is firm and set.
4. Garnish and Serve:
- Once the mousse has set, you can garnish the cake with chocolate shavings, fresh coffee beans, or even edible gold leaf for an extra touch of elegance.
- Carefully remove the cake from the mold if you used one, and serve chilled.
Tips for the Perfect Mocha Mousse Cake:
- Brew Strong Coffee: The coffee flavor is key to the mocha mousse, so make sure to brew a strong cup of coffee to get the best flavor.
- Whip Cream Properly: Whipping the cream to stiff peaks is essential for achieving a light and airy mousse. Be careful not to over-whip the cream, or it may turn into butter.
- Let the Cake Cool Completely: Allow the cake to cool before assembling the mousse, as this ensures that the mousse sets correctly without melting.
- Chill the Cake: Giving the mousse time to firm up in the refrigerator is crucial for the perfect texture and presentation.
Variations:
- Mocha Mousse Cake with Hazelnuts: Add chopped hazelnuts to the mousse for a crunchy, nutty contrast.
- Coffee Liqueur Mocha Cake: Add a tablespoon of coffee liqueur (like Kahlúa) to the mousse for an extra layer of flavor.
- Frosted Version: If you prefer more structure, you can frost the cake with a ganache before adding the mousse layer on top.
Conclusion:
Making an elegant mocha mousse cake is a rewarding process that results in a dessert that is not only delicious but visually stunning. By combining the rich flavors of chocolate and coffee with a smooth mousse and a soft cake, this dessert becomes a perfect treat for any occasion.
