- 1 cup sifted confectioners' sugar
- 1/4 teaspoon salt
- 1/2 teaspoon vanilla extract
- 1 tablespoon water
- 2 drops orange food coloring
- 2 drops green food coloring
- Blend confectioners' sugar, salt and vanilla. Add just enough water to make frosting easy to spread.
- Divide frosting into 2 small bowls. Add 2 drops of orange food coloring to one bowl and 2 drops of green food coloring to the other bowl. Mix each until the colors are even.
- Frost 1 inch of the left side of each Irish Flag Cookie with the green frosting and 1 inch of the right side of the cookies with the orange frosting, leaving the middle inch unfrosted.
