▢½ cup room temperature butter ▢½ cup shortening ▢4 cups powdered sugar ▢3 teaspoon vanilla ▢3-4 Tablespoons of Evaporated Milk
Beat butter and shortening together on medium speed for a few minutes.
Turn down your mixer to slowest speed and slowly add sugar, vanilla.
Beat for about 3-5 more minutes the less milk, the stiffer the batter- which is best if you are cake decorating if you get your frosting too thin, add powdered sugar to stiffen back up.
