This is an Italian wafer biscuit called a pizzelle. It's usually made in a special patterned iron but you can use a waffle iron if you have one.
I used pecans instead of the walnuts to make these chocolate pizzelles. By melting the butter in a large pan, the need for a bowl is eliminated! With or without the chocolate frosting glaze, these are good! - 16 Jun 2008 (Review from Allrecipes USA and Canada)
Tasty but they stuck quite a bit to the iron and it took a bit to get them to come off. - 23 Dec 2010 (Review from Allrecipes USA and Canada)
