The best Sugar Cookie Icing has been a tried and true recipe in our family for years. Without fail, no class party would go by without my mom’s famous cut out sugar cookies making an appearance. Teachers might have highly requested them, but I think Mom made them year after year because I could be trusted transporting them to school.

This sugar cookie icing recipe hardens into a beautiful glassy surface that’s durable enough to be stacked, wrapped, or transported on a bumpy bus ride. It’s like a sugar force field for cookies.

(Now that I’m pondering it…that’s most likely why Mom sent us with homemade peanut brittle and caramel corn for teacher’s gifts. They’re also delicious and durable!)

How Do You Make Cookie Icing That Hardens?

The trick to getting sugar cookie icing to harden is in the ingredients, powdered sugar, milk, and corn syrup. The extract adds a boost of flavor. The small amount of corn syrup achieves that shiny, glossy surface.

Since there is no butter or fat in the recipe, this icing will harden similar to royal frosting. But, unlike royal frosting, the ingredients are simple, and this frosting impressively is made in only 5 minutes.

How To Make Sugar Cookie Icing

  1. Sift powder sugar into a bowl.
  2. Add corn syrup, extract, and milk.
  3. Stir ingredients vigorously until no lumps remain. If making colored icing, divide into bowls and add food coloring.
  4. To frost cookies, pipe an outline around the edge of the cookie. Fill in outline with icing.

TIPS FOR MAKING SUGAR COOKING ICING AND DECORATING

  • Start with a couple teaspoons less of milk. Add the last 2 teaspoons as necessary.
  • To achieve the perfect consistency add more powdered sugar to thicken and a touch of milk to thin.
  • You’ve reached the correct consistency for frosting if a scoop of icing slowly falls off the spoon.
  • Traditionally sugar cookie icing is flavored with almond or vanilla extract, but orange, lemon, maple, or coconut extracts can also be substituted.
  • Sifting the powder sugar before adding milk will eliminate any potential lumps in the frosting.
  • Pipe an outline of icing and fill in for pristine edges. Alternatively spread it on with a small knife and decorate with sprinkles.
  • This frosting hardens quickly so have sprinkles ready to put on immediately.
  • Before stacking or wrapping cookies, make sure the icing is completely hard. Set cookies on a baking sheet for 12 hours.
