Vanillekipferl are very traditional German and Austrian Christmas Cookies. There is no Advent or Christmas without these typical cookies in the shape of a horseshoe or half moon. Use the best vanilla bean you can get, because it makes these cookies so special. The dough is a shortcrust and to shape the cookies might be tricky sometimes, because the dough will not stick together as you would like it to. But if that happens, the dough is right on, just be patient and take some time.
