Place a small glass bowl and the metal beaters of a hand-held mixer in the refrigerator for at least an hour or in the freezer for 10 minutes.
Remove the bowl and beaters, and add the heavy cream to the bowl. Beat to the soft peak stage, about 2-3 minutes.
Add the Greek yogurt and liquid stevia. Beat to the stiff peak stage, about 1-2 minutes. Chill until ready to serve.
