Tips & Tricks
Here are a few tips to keep in mind when making this sugar cookie icing recipe.
- Use gel food coloring if possible. Gel food coloring does a wonderful job of creating the most vibrant shade for the cookie icing and blends the easiest.
- Add more powdered sugar if needed for liquid food coloring. If you do use liquid food coloring, know that it can thin out the icing so you may need to add more powdered sugar to thicken the recipe.
- Separate the icing before adding color. 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.
- How much does this sugar cooking icing recipe make? 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.
Can I Make This Ahead Of Time?
Yes! You can definitely make this sugar cookie icing 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 so that it’s easier to pipe onto the cookies.

I’ve been trying to find an easy cookie icing that would harden and be easy to make/use. This post came along at the perfect time. Now I can whip up and decorate cookies for the family. friends ‘n neighbors. TY for sharing.
Glad you found it Debra. Have fun decorating!
What can be used instead of milk? First, won’t it go sour if left out? Plus cannot have any milk protein, therefore no milk. Thank you
Hi Vikki. The icing will not sour but I understand your concern about the milk protein. Try replacing the regular milk for unsweetened coconut milk. The results will be very similar.
