Mix sugar cookie dough and refridgerate for a few hours.
Using a cookie scoop, scoop out cookie balls and place on cookie sheet.
After all the cookie balls are set out, go back and re-roll each dough ball so there are no cracks in the dough, and the whole ball is a uniform circle.
Using a fork or spoon, dip your balls in the milk, tap off any excess milk on the side of the bowl.
Dip the dough ball into a small bowl with sprinkles, covering the whole ball equally.
Place the dough balls back onto the cookie sheet and bake as directed on your recipe.
