Glossy Sugar Cookie Icing (Printable)

Quick glossy icing that dries firm and smooth for decorating sugar cookies.

# What You’ll Need:

→ Icing Base

01 - 2 cups powdered sugar, sifted
02 - 2-3 tablespoons milk (dairy or non-dairy)
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 Steps:

01 - In a medium bowl, whisk together the powdered sugar, 2 tablespoons of milk, corn syrup, and vanilla extract 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 if using 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.

# Expert Tips:

01 -
  • You probably have everything in your pantry right now, no special shopping trip required
  • The icing sets firm enough to stack cookies but stays soft enough to bite through without cracking
02 -
  • Warm weather and humidity make icing thinner, so add liquid more slowly on summer days
  • If your piping tip keeps clogging, your icing is too thick—add just a few drops of milk
03 -
  • For extra shine, increase corn syrup to 1.5 tablespoons, though this slightly extends drying time
  • Use toothpicks to pull and manipulate wet icing into detailed designs without special tools
