Using a standing mixer, beat the butter on medium speed until creamy
Mix in the powdered sugar, heavy whipping cream, and vanilla extract until combined and smooth
If the frosting is to thin, mix in 1/4 C more of powdered sugar
Once the frosting is combined and smooth, scoop into a container with a sealed lid and place into the fridge for up to 1 week or in the freezer for up to 3 months
Before using for cupcakes or to frost a cake, allow to thaw to room temperature and beat again to make creamy and thick.
ENJOY!
