Learn how to make the best sugar cookie icing that dries hard and smooth every time. This beginner-friendly royal icing recipe is perfect for detailed holiday decorating and cut-out cookies.

Ingredients

Scale
  • 4 cups powdered sugar, sifted
  • 3 tablespoons meringue powder
  • 6 tablespoons warm water
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon clear vanilla extract (optional, for whiter icing)

Instructions

  1. In a large bowl, combine the sifted powdered sugar and meringue powder.
  2. Add the warm water and extracts to the dry ingredients.
  3. Beat with an electric mixer on low speed until the ingredients are 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 thick, glossy, and holds stiff peaks. This step incorporates air and helps the icing dry hard.
  5. Check the consistency. For outlining, the icing should be thick. For flooding (filling in areas), add water one teaspoon at a time until the icing flows slowly off a spoon in a ribbon that disappears into the bowl after about 10 seconds.
  6. Divide the icing into separate bowls for coloring, if desired. Use gel food coloring for the best results.
  7. Use the icing immediately for decorating cookies.
  8. Allow the decorated cookies to dry completely at room temperature for several hours, or overnight, until the surface is hard to the touch.

Notes

  • For a corn syrup free cookie icing that hardens, this meringue powder recipe is your answer.
  • If your icing seems too thin after mixing, add powdered sugar one tablespoon at a time until you reach the desired consistency.
  • If your icing is too thick, add water half a teaspoon at a time. Do not over-add liquid.
  • This icing is excellent for cut out cookie icing projects.
  • If you are interested in meal planning for your baking projects, remember that proper planning helps reduce waste.
  • Save this recipe on Pinterest for your next holiday cookie decorating session.
