- 1/2 cup sugar
- 3 large eggs
- 1 teaspoon vanilla extract
- 1/4 teaspoon salt
- 2 teaspoons gelatin (or agar-agar for a vegetarian version)
- 1 tablespoon water
For the Cake Base:
- 1 cup almond flour (or gluten-free biscuits, crushed)
- 1/4 cup melted butter
- 2 tablespoons sugar
- 1/4 cup brewed coffee (optional for flavor)
For the Chocolate Ganache (optional):
- 1/2 cup heavy cream
- 1/2 cup semi-sweet chocolate chips
Equipment
- 9-inch springform pan
- Medium saucepan
- Mixing bowls
- Electric hand mixer or stand mixer
- Whisk
- Spatula
- Measuring cups and spoons
- Small bowl for blooming gelatin
Step-by-Step Instructions
1. Prepare the Cake Base
- In a mixing bowl, combine the almond flour (or crushed gluten-free biscuits), melted butter, sugar, and brewed coffee. Stir until everything is evenly mixed.
- Press the mixture into the bottom of your springform pan, making sure it’s compacted well to form a solid base.
- Place the pan in the refrigerator to chill while you prepare the mousse.
2. Bloom the Gelatin
- In a small bowl, sprinkle the gelatin over 1 tablespoon of water and let it sit for 5 minutes to bloom.
- After blooming, gently heat the mixture over low heat until the gelatin dissolves completely. Set it aside to cool.
3. Make the Coffee Mousse
- In a medium saucepan, combine the coffee, sugar, and salt. Heat over medium heat until the sugar dissolves.
- In a separate mixing bowl, whisk the eggs and vanilla extract until well combined.
- Gradually pour the hot coffee mixture into the egg mixture while continuously whisking to temper the eggs.
- Pour the egg-coffee mixture back into the saucepan and cook over low heat, stirring constantly, until it thickens slightly (about 5 minutes).
- Remove from heat and stir in the dissolved gelatin. Let the mixture cool completely.
4. Whip the Heavy Cream
- In a separate bowl, whip the heavy cream with an electric mixer until soft peaks form.
- Gently fold the whipped cream into the cooled coffee mixture, being careful not to deflate the mousse. The result should be smooth and fluffy.
5. Assemble the Cake
- Pour the coffee mousse onto the chilled cake base in the springform pan.
- Smooth the top with a spatula and refrigerate for at least 2-3 hours, or until the mousse is set and firm.
6. Prepare the Chocolate Ganache (optional)
- For the ganache, heat the heavy cream in a saucepan over medium heat until it just begins to simmer.
- Remove from heat and stir in the chocolate chips until smooth and glossy.
- Let the ganache cool slightly before pouring it over the set mousse. Use a spatula to spread it evenly.
7. Serve and Enjoy
- Once the ganache has set, carefully remove the sides of the springform pan.
- Slice and serve the coffee mousse cake to enjoy its rich, creamy, and flavorful layers.
Pro Tips
- Whip the Cream Properly: Be sure to whip the heavy cream until soft peaks form before folding it into the coffee mixture. This ensures a smooth and airy mousse texture.
- Use Freshly Brewed Coffee: For the best coffee flavor, use freshly brewed espresso or strong coffee. It will give the mousse cake a deep, authentic coffee taste.
- Chill the Cake Well: The mousse needs to be chilled for at least 2-3 hours to set properly. It’s a great make-ahead dessert that you can prepare the day before.
- Add Liqueur for Extra Flavor: For an adult twist, add a tablespoon of Kahlúa, Baileys, or another coffee liqueur to the mousse for enhanced flavor.
- Customize the Base: You can swap the almond flour for gluten-free biscuits to make the base even more decadent, or add a layer of crushed hazelnuts for added texture and flavor.
Variations You Can Try
1. Coffee and Hazelnut
Add crushed hazelnuts to the cake base for an extra nutty, crunchy texture that pairs beautifully with the coffee mousse.
2. Vegan Version
Use coconut milk or almond milk for the mousse and replace the gelatin with agar-agar for a vegan-friendly alternative.
3. Mocha Version
Add cocoa powder to the mousse for a delightful mocha flavor that combines both coffee and chocolate in every bite.
4. Fruit Layer
Add a layer of fresh berries, like raspberries or strawberries, on top of the mousse before chilling for a fruity contrast to the rich, creamy coffee mousse.
