This wonderfully creamy keto cream cheese frosting is quickly whipped by hand. There's no need for powdered sugar! It's beautifully thick and holds its shape well.
Place the softened cream cheese in a bowl. Add the vanilla and sweetener.
Using a hand whisk, whisk vigorously until the frosting is completely smooth and fluffy, for about 2 minutes. If you prefer to use an electric whisk, start whisking on low speed until the mixture is uniform, then increase the speed to medium and beat until fluffy for about 1 minute, scraping the sides of the bowl with a rubber spatula as needed.
Spoon the frosting on top of six cupcakes or use a piping bag. You can also use this frosting to frost a single-layer cake. Double the recipe if you need it for 12 cupcakes or a 2-layer cake.

Notes
A granulated sweetener will have a grainy mouthfeel. It's important to use a powdered sweetener if not using stevia.
I usually use this frosting immediately to frost cakes or cupcakes, then store the finished product in a sealed container in the fridge. It's been my experience that these frosted baked goods keep well when stored this way for 3-4 days.
You can also keep the frosting itself in the fridge, in an airtight container, for 3-4 days. Give it another good mix before using it. I don't recommend freezing this frosting.
