This is an excellent basic buttercream frosting recipe that I use to frost cinnamon rolls as well as cakes…and sometimes just eat it with a spoon!
1 pound powdered sugar (sifted if you’re adding food coloring)
1 stick salted butter (softened)
¼ cup milk
A splash of vanilla
A couple of shakes from the salt shaker
Place ingredients in mixer bowl, and beat until fluffy.
