Sugar cookie lovers won’t want to miss this 3-ingredient recipe for The Best Sugar Cookie Icing that sets firm without the need for meringue powder or egg whites.
Table of Contents
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.
Is Cookie Icing the Same as Royal Icing?
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.

I am excited to try this recipe as a flood icing for sugar cookies! Would it be okay as a base for a stiffer consistency, like royal icing? Or would it hold up as an outline consistency if I made this recipe stiffer with more powdered sugar? Based on the ingredients I would think it’ll be delectable :)
Hi Steph! You could absolutely use this as a flood icing (I have done that many times!). It could also work as an outline frosting, but you’d need to stiffen it with additional powdered sugar. Enjoy!
Hi, thank you for the recipe. How long can the frosting be left at room temperature?
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.
If I use dairy free butter will this still work? Thank you
Hi Anna! I haven’t tried this recipe with that substitute so I’m not sure. Let me know if you try it!
Hi there! Is there a chocolate version of this??
Hi Katie! It’s in the works :)
Can this be made a day ahead? If so, how should it be stored?
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.
Can I use 2% milk instead of whole milk?
Sure!
This looks great. I’m wondering if the cookies are stackable after they set. Thanks
Hi Marianne! I would not recommend stacking them, as they may smear slightly if not fully set.
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! :)
AMAZING! I’m so thrilled you enjoyed the recipes, Carly!
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.
Hi there! I haven’t tried making a recipe with those ingredients so I’m not sure.
Could this icing be piped on I stead of the other 2 methods mentioned?
That should work! I’d use it as a flood icing and not an outline.
