Make and refrigerate the dough up to 24 hours ahead of cutting and baking.
To easily roll the dough in sprinkles, place a sheet of plastic wrap on a cookie sheet or tray with sides. Place roll in plastic wrap, and pour 3 tablespoons sprinkles over dough. Move roll of dough back and forth, using plastic to press sprinkles onto sides of dough, until sides are completely coated. Wrap in plastic wrap, and refrigerate.
