Rich with butter and nuts, these little shortbread-like �cakes� seem to melt in your mouth. Roll these cookies twice in confectioners sugar; the first rolling allows the sugar to melt into the cookie, the second rolling gives the finished snowy-white topping, making a festive favorite holiday cookie. This cookie is known by many names including Mexican Wedding Cakes, Swedish Tea Cakes, Italian Butter Nut Cookies, Butterballs, and Snowballs.
