Steps
In a mixing bowl, add heavy whipping cream, cocoa powder, erythritol, vanilla extract, and salt.
Using an electric mixer, beat on medium speed until soft peaks form.
If using cream cheese, soften it and add it to the mixture, then continue to beat until well combined and fluffy.
Spoon the mousse into a serving dish or glass.
Chill in the refrigerator for at least 30 minutes before serving to enhance the flavor and texture.
