Simple Cookie Glaze

"This glaze dries hard and shiny, and is perfect for coating the top of your cookies in preparation for decorating with food-safe pens or makers. This glaze is a little on the thick side, and it isn't perfectly smooth when you apply it, but should settle into a smooth surface within half a minute or so. Glaze one cookie and set it aside for a minute. Has the glaze settled into a smooth surface? If so, it's the right consistency. Remember, it's easier to add more liquid than to stir in more sugar, so start with a glaze that's thicker than you think it should be, then add milk little by little to adjust the consistency.
