Glace Icing

Yield: 2 cups

Prep Time:10 min


1 pound powdered sugar
1/4 cup + 2 Tablespoons milk
1/4 cup + 2 Tablespoons light corn syrup
2 teaspoons vanilla extract (or almond, if desired)


1. In a mixing bowl, mix sugar and milk first. Add corn syrup just until combined. Divide (if desired) to add extract for flavor and add color as needed.

2. Ice cookies as desired. Cookies sometimes take up to 12 hours to dry completely. Once dry, you should be able to stack them without ruining the icing.


*I like to use this icing recipe with No Fail Sugar Cookies.
*This type of icing is very forgiving- experiment with consistency. You don't want it too runny or too stiff. If it's too runny, add more sugar, too thick... add more milk.
*Remember when you add color that it is easier to put it in than to take it out!
*This icing takes a long time to dry after you put it on a cookie, but until then- it turns to concrete in seconds. Keep your containers covered until you are ready to use it.
*All of these cookie tips come from a wonderful resource:

    Once the cookies are made and decorated, what is the shelf life? Would you just store them in a closed container? (At room temperature or refrigerated?) Can they be frozen once they are decorated?

      I don’t like to freeze them already decorated, though I have done so with holiday cookies once in a while. They should be fine for a week or so if they’re sealed well.

    I am making these for my son’s birthday and I’m clueless haha. First time icing… I was planning on buying the icing bags and tips. Is that how you applied the icing? The only stupid question is the one not asked right????

      Yes, I use a small tip to edge the cookies. And a steady hand!

    Cookie newbie here but where do you keep the cookies while the icing is drying?  Keep them out on the counter and then store them?

    • Lori Lange wrote:

      Yes, I usually lay them out on my counter.
