Poured Cookie Icing
This is a great recipe I found today and tried on my sugar cookies. It dries fast and shiny to a hard finish. I really liked it and there's no problem adding food coloring.
1 cup sifted confectioners' sugar
2 teaspoons milk
2 teaspoons light corn syrup
Place sugar and milk in bowl. Stir until mixed thoroughly. Add corn syrup and mix well. For filling in areas, use thinned icing (add small amounts or light corn syrup until desired consistency is reached).
