How to Make Coffee Mousse Cake
Prepare the Cake Base
Preheat oven to 350°F (175°C) and grease a springform pan. In a bowl, whisk together flour, baking powder, cocoa powder (if using), and salt. In another bowl, beat eggs and sugar until light and fluffy. Add milk, oil, and vanilla extract. Fold in the dry ingredients gently. Pour the batter into the pan and bake for 18-20 minutes, or until a toothpick inserted comes out clean. Let the cake cool completely.
Make the Coffee Mousse
Dissolve instant coffee or espresso powder in 2 tablespoons of hot water and set aside. Bloom the gelatin by sprinkling it over 2 tablespoons of water and let it sit for 5 minutes. Heat gently until melted. In a large bowl, beat cold heavy cream and powdered sugar to soft peaks. Add the dissolved coffee and cooled gelatin, then continue to whip until smooth and airy.
Assemble the Cake
Place the cooled cake base back into the springform pan. Pour the coffee mousse over the cake layer, smoothing the top. Refrigerate for 4 hours or overnight until set.
Decorate
Once the mousse has set, remove the cake from the pan. Dust with cocoa powder, add chocolate shavings, or pipe dollops of whipped cream for a stunning finish.
Tips for the Perfect Coffee Mousse Cake
- Use strong instant coffee or espresso powder for an intense coffee flavor.
- Ensure the gelatin mixture is cooled but still liquid before adding to the whipped cream.
- For best results, chill the cake overnight to fully set.
- Slice with a warm knife for clean, neat cuts.
Variations to Try
- Add a layer of chocolate ganache between the cake and mousse.
- Infuse a hint of vanilla or hazelnut extract into the mousse for extra flavor.
- Use gluten-free flour for a gluten-free option.
Serving Suggestions
Coffee mousse cake pairs wonderfully with:
- A hot cup of espresso or cappuccino
- Fresh berries for a fruity contrast
- A drizzle of caramel sauce for added sweetness
Coffee mousse cake delivers the best of both worlds—a bold coffee kick wrapped in a soft, creamy, and light dessert. Whether you’re serving it at a party or enjoying it with family, it’s sure to impress and satisfy coffee cravings.
