Before beginning to decorate your sugar cookies this Christmas season, you'll want to learn how to properly ice them. Christmas Cookie Swap! has a reliable recipe for royal icing and a step-by-step process to help you pipe the icing with success.
Royal icing creates a smooth surface on decorated cookies. It's made with either whipped egg whites or whipped meringue powder, powdered sugar, and water. The addition of just a bit of corn syrup boosts the flavor and helps create a shiny finish.
1 (16-ounce) package powdered sugar
3 tablespoons meringue powder
5 to 6 tablespoons warm water
1 teaspoon light corn syrup
Food coloring paste (optional)
Combine powdered sugar, meringue powder, water, and corn syrup in a large bowl. Beat at medium-low speed with an electric mixer 5 to 7 minutes. Divide and tint with food coloring, if desired. Icing dries quickly, so keep it covered at all times. Makes about 3 cups.
