This recipe is all over the internet. My sister Margie shared it with me. I've made them at least 3 times, but she hasn't tried them yet. I guess I have to make them for her when she comes for Thanksgiving.
I like this icing better for half moon cookies.
You can't really store cookies or cakes iced with this fondant in the refrigerator. A cool room would be better. You CAN store unused fondant in the fridge; just beat it well when you finally use it.
This recipe makes about 1 quart, which is at least twice as much as you'd need for a single recipe of half moon cookies.
