I like how it is just a light glaze of icing. Sprinkles and dragees adhere nicely. You can colour the icing and you can layer it if you wait an hour between colours.

My sugar cookie recipe is a keeper. I recommend it. I used this icing recipe from Ciao magazine.
1 cup icing sugar
1 tablespoon white corn syrup
2 tablespoons water
Mix until smooth. Paint on to the cookies. Sprinkles can be added now but let the icing set for an hour before layering on more colours. Leave cookies 24 hours for the icing to set before packaging.
