While you might be most familiar with smooth, matte royal icing on your sugar cookies, it can be a bit unwieldy to use and mix up. With this in mind, I created a delicious shortcut recipe for cookie icing that achieves nearly the same consistency when set. It’s fast, free of corn syrup and easily sets to form that iconic shiny, flavorful topping for cookies in every color of the rainbow.

While many cookies are often topped with royal icing, this cookie icing differs in that it’s made simply with confectioner’s sugar, butter and milk. No meringue powder or egg whites necessary!

Cookie icing can be used in almost the same way you’d use royal icing. You can dip your cookies directly into the icing, or pipe or spoon on cookie icing to “flood” the tops of your cookies. This cookie icing won’t dry exactly as hard as royal icing, but 10 minutes of cooling time will allow it to fully set.

How Do You Decorate Sugar Cookies Like a Pro?

The real beauty of this recipe is that other than not needing any fancy ingredients, you really don’t need any fancy equipment either. Just a bowl and a whisk will get you in business, and then I use one of two methods to ice my cookies:

  • Dip the cookies into the icing and shake off any excess
  • Use a small spoon or offset spatula to spread the icing atop the cookies

No matter which method you choose, if you’re going the route of sprinkles, it’s important to add them immediately after you apply the icing, as the icing does set semi-firm. If you wait too long, the sprinkles won’t adhere to the icing.

You can also dye this icing any color of the rainbow using either regular food coloring or gel-based food coloring. I prefer the latter because you get a much more vibrant color with just a few drops.

    1. Hi Youssef! It depends on the climate you live in. If it’s relatively dry and not too warm, it’s great at room temp for a few days.

    1. Hi Anna! I haven’t tried this recipe with that substitute so I’m not sure. Let me know if you try it!

    1. It’ll set so it’s best used right away, however you can microwave it to bring it back to a pliable consistency if needed.

  1. 5 stars
    I used your sugar cookie recipe with this icing and everyone agrees that they are the absolute best cookies I’ve ever made! Thank you so much for sharing your easy-to-follow recipes and making me look like a great baker – ha! :)

  2. Hi there
    could the icing work with margarine, water and a non fat milk?
    Slight dairy allergy so always on the lookout for recipes that can be adapted.
