Add the mascarpone, heavy whipping cream, powdered sweetener, and vanilla extract to a bowl. Using a hand mixer with whisk attachments, beat on medium speed for a few minutes or until fully incorporated.
Step 2
The mixture should double in size and become a light and airy mousse. You can adjust the amount of sweetener according to taste. You can also adjust the amount of vanilla.
Step 3
Transfer the mousse to serving glasses or bowls using a piping bag. For the best results, refrigerate the mousse before serving. Another good idea is to chill the bowls before adding the mousse.
Step 4
Garnish the mascarpone mousse with your favorite low-carb berries, and add a few mint leaves. Serve immediately or store for later. Enjoy!
