Roll the dough balls in granulated or sparkling sugar to coat before placing onto the prepared baking sheets. Leave 2″ between them on all sides; they’ll spread as they bake.
Bake the cookies for 12 to 15 minutes, until they’re puffed and their edges are set.
Remove the cookies from the oven, and cool completely right on the pan.
Store cookies, well wrapped, at room temperature for several days; freeze for longer storage.
