This recipe provides a simple, foolproof method for making sugar cookie icing that dries completely hard and glossy. This icing is perfect for decorating cutout cookies intended for gifting, stacking, or achieving professional-looking designs.

Ingredients

Scale
  • 3 cups Powdered Sugar (sifted)
  • 1/4 cup Milk or Water
  • 1 teaspoon Light Corn Syrup

Instructions

  1. In a medium bowl, whisk together the sifted powdered sugar and the milk or water until smooth.
  2. Add the light corn syrup to the mixture.
  3. Whisk vigorously until the icing is very smooth, shiny, and holds soft peaks. The corn syrup helps create a hard, glossy finish.
  4. If the icing is too thick for piping fine lines, add milk, 1/2 teaspoon at a time, until the desired consistency is reached.
  5. If the icing is too thin to hold a shape, add sifted powdered sugar, 1 tablespoon at a time, until it thickens.
  6. Use immediately to flood or outline your cooled sugar cookies.
  7. Allow the iced cookies to sit at room temperature until the icing is completely dry and hard to the touch. This usually takes several hours, depending on humidity.

Notes

  • Always use sifted powdered sugar to prevent lumps in your smooth icing.
  • Light corn syrup is the key ingredient that promotes a hard, non-tacky finish when dry.
  • For coloring, use gel food coloring for the best results without thinning the icing too much.
  • Store unused icing covered tightly with plastic wrap pressed directly onto the surface to prevent a crust from forming.
