1In a medium saucepan, heat the milk over medium heat until it begins to simmer.
Add the cocoa powder, instant coffee, and sugar to the milk, whisking continuously until the mixture is smooth and the sugar is dissolved.
Remove the saucepan from the heat and let the mixture cool to room temperature.
Once cooled, gently fold in the whipped cream until fully incorporated.
Pour the mousse into serving glasses or bowls and refrigerate for at least 2 hours or until set.
Serve chilled and enjoy your Coffee Chocolate Mousse.
