Whipped Buttercream Frosting

Mix butter with whisk attachment in mixer until smooth and creamy. Add 3 cups powdered sugar, vanilla, and salt. Start the mixer on low then mix on high for 2–3 minutes. If the frosting is not thick enough, or not to your preference, add another 1/2 cup of sugar. Add heavy whipping cream and mix on high for 1–2 more minutes.

Note: Do not skip the heavy whipping cream (you can use milk if you do not have cream, but the cream makes it richer). You will be shocked how this last step really lightens the frosting and makes it fluffier and whiter.
