Learn the simple method for making the best sugar cookie icing that hardens completely, dries glossy, and sets firm for professional decorating results every time.

Ingredients

Scale
  • 4 cups powdered sugar, sifted
  • 3 tablespoons meringue powder
  • 6 tablespoons warm water
  • 1 teaspoon vanilla extract

Instructions

  1. In a medium bowl, whisk together the sifted powdered sugar and meringue powder until fully combined.
  2. Add the warm water and vanilla extract to the dry ingredients.
  3. Using an electric mixer on low speed, mix the ingredients until just combined. Scrape down the sides of the bowl.
  4. Increase the mixer speed to medium-high and beat for 5 to 7 minutes until the icing is very smooth, thick, and holds stiff peaks. This step incorporates air and helps the icing set hard.
  5. Test the consistency. For outlining, the icing should be thick. For flooding, add water one teaspoon at a time until the icing flows slowly off the whisk in a thick ribbon that disappears into the bowl after about 10 seconds.
  6. Divide the icing into bowls if you plan to color it. Add gel food coloring sparingly and mix until the color is uniform.
  7. Use the icing immediately for decorating your cooled sugar cookies.
  8. Allow the decorated cookies to sit uncovered at room temperature for several hours, or overnight, until the icing is completely dry and hard to the touch.

Notes

  • For a glossy finish, avoid over-beating once the desired consistency is reached.
  • If the icing becomes too thick while decorating, stir in a few drops of water. If it is too thin, add a tablespoon of sifted powdered sugar.
  • This icing sets solid, making your cookies stackable and ready for gifting.
