How to Make Best Sugar Cookie Icing

Ingredients

  • 3 cups (360 g) powdered sugar, sifted
  • 3–4 Tbsp milk or water
  • 2 Tbsp light corn syrup
  • 1 tsp vanilla extract (or ½ tsp vanilla + ½ tsp almond extract)
  • Pinch of fine sea salt
  • Gel food coloring, as desired

Directions

  1. Sift the powdered sugar into a medium bowl.
  2. Add 3 tablespoons of milk or water, corn syrup, vanilla (and any other extract), and a pinch of salt. Stir until smooth.
  3. Adjust consistency:
    • If too thick, add more liquid ½ teaspoon at a time.
    • If too thin, add more powdered sugar.
    • For outlining, keep icing on the thicker side; for flooding, thin slightly until a ribbon of icing disappears back into the bowl in about 8-12 seconds.
  4. Divide icing into bowls and add gel food coloring as desired; stir until evenly colored.
  5. Transfer icing to piping bags, squeeze bottles, or use small spoons for spreading.
  6. Decorate completely cooled sugar cookies. Allow icing to dry at room temperature for several hours, or overnight, until the surface is firm.

FAQs

Can I use regular food coloring instead of gel?
Yes, but gel food coloring is recommended because it doesn’t thin the icing as much as liquid colors do.

Can I freeze sugar cookie icing?
No, it’s best to store it in the fridge and use it fresh, as freezing can change its texture.

How can I make my icing shiny?
Adding corn syrup is what gives it that beautiful shine! Just be sure to mix it well.
