Prep Time 10 minutes
Total Time 10 minutes
Servings 1.5 cups

Ingredients

  • ½ cup unsalted butter softened to room temperature
  • 2 ½ cups powdered sugar
  • 2 teaspoons vanilla extract
  • teaspoons salt
  • 2-3 tablespoons milk or heavy cream use 2-3 tablespoons, as needed

Instructions

  • Beat the softened unsalted butter (½ cup, i.e. 1 stick) on medium-high speed for 2 minutes until smooth. Turn the mixer to low speed then add the powdered sugar ¼ cup at a time (2 ½ cups total). You may need to stop and scrape down the sides.
  • Add vanilla extract (2 teaspoons) and salt (⅛ teaspoon) and turn mixer to medium speed. One tablespoon at a time, add milk or heavy cream (2-3 tablespoons total). Beat on high for 2-3 minutes until creamy and the frosting is at a good consistency to pipe. If it looks too runny, add more powdered sugar. If it looks too stiff, add a tiny bit of milk until you get to the desired consistency.
  • This will make just enough frosting to fill about 12 cookie sandwiches (2 tablespoons of frosting each) or to pipe a border & add a message to a round cookie cake.
