Ball cookies are simply cookies that are hand-formed into round ball shapes. Some are then baked or fried; others are no-bake recipes. Popular ball cookies are Mexican Wedding Cookies, Buckeyes, and Rum Balls.  Unbaked ball cookies will stay round, but most baked ball cookies will actually flatten out a bit to form a rounded dome…this is normal. For the tenderest cookies, handle the dough as little as possible. For serving at parties, these look great served in paper candy cups. They will look best if you attempt to make them all a uniform size.
