Royal Icing for Cookies - Foolproof Recipe

Course Dessert


  • 2 egg whites room temperature
  • 3 cups powdered sugar
  • 1/4 tsp cream of tartar
  • pinch of salt
  • optional - dash of vanilla extract


  1. Beat the egg whites, powdered sugar, cream of tartar, and salt on medium speed in an electric mixer (use the whisk attachment).
  2. Optionally add vanilla (or other flavorings or colors), then increase the mixer's speed to medium-high and beat until stiff peaks form. The volume will nearly triple. (7-8 minutes)
  3. If you're not using it right away, cover tightly with plastic wrap so it won't dry out. It's fine at room temperature. Otherwise, put it right into your piping bag and go ahead and use it.
