Key Ingredients You’ll Need

Powdered Sugar: This will be used to thicken the icing, but also add sweetness along with the light corn syrup which will make it shiny.

Vanilla: I prefer using clear vanilla extract so that the icing is bright white.

Food Coloring: This is an optional ingredient, but can be used to decorate and color the frosting.

How To Make Sugar Cookie Icing

Step 1. In a medium-sized bowl, add the powdered sugar, 2 tablespoons of milk, corn syrup, and vanilla extract, and combine until fully incorporated. You can add more milk if the frosting is too thick. I recommend adding a teaspoon at a time until the frosting is pipeable. If you add too much milk, just add more powdered sugar until you reach the desired thickness.

Step 2. If needed, you can color the icing by separating the icing into small bowls and adding your desired colors. Put the prepared frosting into piping bags with a piping tip. You can see the best way to frost the cookies below and decorate them with sprinkles or candies if desired. Once you’ve frosted and decorated the cookies, you can set them aside to harden. You will want the frosting to harden completely before serving, stacking, or storing.

How Long Does This Icing Take To Harden?

This recipe will take up to 24 hours to harden depending on the climate in your household. The top layer of the icing will harden after just a couple of hours. I recommend hardening overnight for the best results.

How To Decorate Sugar Cookie Icing?

You will first want to use the piping bags of icing to outline each of the cookies before flooding the icing into the center. You can use the tip of a toothpick to move the frosting around to fill it out. If you want to add sprinkles or other forms of decorations, I would add them at this point. After you are done decorating, put them in a single layer in an airtight container and store them for up to 24 hours until they are fully hardened.

Can I Make This Ahead Of Time?

Yes! You can definitely make this recipe up to 2 days in advance. You can keep the prepared icing in the fridge in an airtight container until you are ready to use. Before use, you will want need to bring the icing to room temperature.

Do I Have To Use Corn Syrup?

I believe it is a must to use corn syrup in this recipe! This ingredient makes the icing come out shiny and even helps harden the icing faster. So, I recommend keeping this crucial ingredient in the recipe.

Tips & Tricks

  • Its best to use gel food coloring instead of liquid because it blends easier, but you can use liquid if needed. The liquid food coloring can thin out the icing so you may need to add more powdered sugar to thicken the recipe.
  • Gel food coloring does a wonderful job of creating the most vibrant shade for the cookie icing.
  • If you plan on using multiple different colors, you will want to divide the icing into different bowls before adding each color. It’s also best to use separate piping bags for each color.
  • This recipe will make about 1 1/2 cups of icing which should be enough for a dozen cookies. You can double or cut the recipe in half depending on how many cookies you are making.
