In a large mixing bowl, whip the heavy cream and vanilla with a hand mixer or stand mixer until soft peaks form.
Add the powdered erythritol and xanthan gum (if using) and whip until fully combined.
Transfer the mixture to a freezer-safe container, spreading it out evenly.
Cover and freeze for at least 4 hours, stirring the mixture every 30 minutes for the first 2 hours to prevent ice crystals and ensure a creamy texture.
Scoop and serve once fully frozen. Enjoy!
