Sugar Cookie Icing (Printable)

A quick 4-ingredient glaze that sets beautifully for decorated cookies

# What's Needed:

→ Icing Base

01 - 2 cups powdered sugar, sifted
02 - 2-3 tablespoons milk
03 - 1 tablespoon light corn syrup
04 - 1/2 teaspoon pure vanilla extract

→ Optional Color and Decoration

05 - Food coloring (gel or liquid, as desired)
06 - Sprinkles or colored sugars (optional)

# How to Make It:

01 - Whisk together the powdered sugar, 2 tablespoons of milk, corn syrup, and vanilla extract in a medium bowl until smooth and glossy.
02 - If the icing is too thick, add additional milk 1/2 teaspoon at a time until it reaches a thick but pourable consistency.
03 - Divide the icing into separate bowls for multiple colors. Stir in food coloring a few drops at a time until the desired color is achieved.
04 - Use immediately to decorate cooled sugar cookies. Dip cookies, spread with a knife, or pipe designs using a piping bag or squeeze bottle.
05 - Allow decorated cookies to dry at room temperature for at least 4 hours or until the icing is completely set.

# Tips for Success:

01 -
  • It comes together in under ten minutes with ingredients you already have in the pantry
  • The consistency is forgiving enough for beginners but professional enough for detailed designs
02 -
  • This icing starts setting quickly so have all your colors and tools ready before you begin mixing
  • Humidity affects drying time significantly, on rainy days give cookies extra time to set
03 -
  • Test your icing consistency on a spare cookie or piece of parchment before committing to your decorated ones
  • To prevent colors from bleeding, let each layer dry completely before adding the next
