In two wide-mouth mason jars, add 1 cup heavy whipping cream, 2 tbsp monk fruit sweetener, 1 scoop collagen powder, and ¾ tablespoons vanilla extract.
Shake vigorously for 5 minutes.
Place jars in the freezer and allow to freeze until solid, about 4 - 6 hours. (Approximately every 2 hours, shake jars a few times to move cream around).
