Glace Icing

Yield: 2 cups

Prep Time: 10 min

Glace Icing


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:

    I have to try these… one, because they look delicious, and oh so cute… two, because my son’s name is Brooks, and that’s for sure the first time I’ve seen it on a cookie!! =)

    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?

      Yes, I usually lay them out on my counter.

    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!
