Place all ingredients into the bowl of a stand mixer. Stir on low to combine. Scrape sides and mix again. Then whip on high for 30 seconds to 1 minute to get a completely smooth and creamy frosting. Use as desired.
Notes
This recipe will frost 24 cupcakes, a 2 layer cake or as seen here 1-9x13 with a smaller 6-inch cake on top.
