Grab a medium mixing bowl and use a hand mixer to beat the cool, softened cream cheese until it's wonderfully smooth and creamy.
Now, add your chosen low-carb powdered sweetener to the bowl. Beat again until the mixture becomes visibly lighter and takes on a fluffy texture.
Stir in the vanilla extract, ensuring it's fully incorporated into the frosting.
Introduce the softened butter to the mix. Continue beating until all the ingredients are beautifully whipped together, making the frosting airy and delightful.
Give it a taste! If you prefer it sweeter, feel free to add a little more powdered sweetener or a few drops of liquid stevia, then beat briefly to blend.
Pop the frosting into the refrigerator to chill until you're ready to use it.
Just before you're about to frost your favorite low-carb treats, give the frosting one last quick beat to bring back its light and fluffy consistency.
