Although this icing recipe is sooo simple and quite possibly can't even be considered a recipe, if I don't post this we might forget how to make this and our home would never see iced cookies again!
1 cup powdered sugar
1 TBSP water (or milk)
1/2 TSP vanilla extract
Mix powdered sugar, water and vanilla.
Add in 2-3 drops of food coloring.
Drizzle over sugar cookies.
Let set for 30-60 minutes.
