05Working with half of the chilled dough at a time and keeping the rest in the fridge, roll the dough by 2 teaspoonfuls between your palms into balls. Arrange the balls on a large baking sheet, spacing them 1/2 inch apart.
06Bake the cookies until golden brown on the bottom and just pale golden on top, about 18 minutes. Cool the cookies for 5 minutes on the baking sheet. Toss the warm cookies in the powdered sugar. Transfer the sugar-coated cookies to a rack to cool completely. The cookies can be prepared up to 2 days ahead. Once cooled, store them in an airtight container. You need to make sure they are cooled before storing them, otherwise they will get soggy. Sift additional powdered sugar and cinnamon over the cookies if desired before serving.
