1. Prepare the Coffee Mixture

1. Brew the Coffee: Brew a strong cup of coffee, then allow it to cool slightly. If you like an extra coffee kick, stir in the instant coffee granules.
2. Combine the Ingredients: In a mixing bowl, combine the cooled coffee, sugar, and vanilla extract. Stir until the sugar is dissolved.

2. Prepare the Creamy Base

1. Mix Mascarpone: In another bowl, whisk the mascarpone cheese until smooth. If you’re using cream cheese, make sure to soften it before mixing to avoid lumps.
2. Fold in Whipped Cream: In a separate bowl, whip the heavy cream until stiff peaks form. Gently fold the whipped cream into the mascarpone mixture, creating a light, creamy texture.

3. Combine the Coffee and Cream Mixtures

1. Combine: Slowly pour the coffee mixture into the creamy mascarpone base, folding gently until fully combined. Be careful not to deflate the whipped cream too much—this mousse should remain light and fluffy.

4. Chill the Mousse

1. Refrigerate: Spoon the mousse into serving glasses or bowls. Cover with plastic wrap and chill in the refrigerator for at least 3 hours, or overnight for best results. The mousse will firm up and become more flavorful as it chills.

5. Garnish and Serve

1. Garnish: Just before serving, garnish the mousse with a dusting of cocoa powder or chocolate shavings for a beautiful, finishing touch.
2. Serve: Serve chilled and enjoy the creamy, dreamy goodness of your homemade coffee mousse!
