In a bowl, with either your KitchenAid mixer or a hand mixer, start whipping the cream on medium speed.
As you start to see a bit of volume, slowly add in the Stevia, followed by the Cream of Tartar, and finally by the Vanilla.
Continue mixing until you start to see the whipped cream hold it's shape as you move the beaters around the bowl. When you think it's ready, stop the mixer, then look at how the whipped cream hangs off of the beaters. If it holds a soft peak, it's ready!
Note: be careful not to beat too much, or you'll have sweet butter on your hands!
