Glossy Sugar Cookie Icing (Printer-friendly)

Glossy icing that dries smooth and firm for beautifully decorated cookies

# What You'll Need:

→ 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 Prepare:

01 - In a medium bowl, whisk together powdered sugar, 2 tablespoons milk, corn syrup, and vanilla extract until smooth and glossy. Ensure all lumps are dissolved for a uniform consistency.
02 - Test the icing thickness. If too thick to pour, add additional milk 1/2 teaspoon at a time, mixing thoroughly after each addition, until achieving thick but pourable consistency that spreads easily but holds its shape.
03 - For multiple colors, divide icing into separate bowls. Add food coloring drop by drop, stirring continuously until reaching desired shade intensity. Gel coloring provides deeper colors with less liquid.
04 - Decorate completely cooled sugar cookies immediately. Choose application method: dip cookie tops into icing, spread with offset spatula or knife, or pipe detailed designs using piping bag fitted with small round tip or squeeze bottle.
05 - Place decorated cookies on wire rack or parchment-lined surface. Allow to dry undisturbed at room temperature for minimum 4 hours or overnight until icing forms firm, matte finish that doesn't transfer to touch.

# Expert Advice:

01 -
  • You can mix up this glossy icing in under ten minutes with ingredients you already have in your pantry
  • The consistency is forgiving and perfect for beginners, but professional enough that experienced bakers swear by it
02 -
  • I learned the hard way that warm cookies and this icing are enemies, your cookies must be completely cool or the icing will slide right off
  • Corn syrup amounts can be adjusted slightly for different effects, more syrup means more shine but slightly longer drying time
03 -
  • Use an offset spatula for the smoothest spread, the angle lets you glide over icing without dragging
  • Let your base layer of icing dry for at least fifteen minutes before adding details or piped designs on top
