One of my favorite cookies before being diagnosed were Pizzelle. They are light, crisp Italian cookies that are just delightful. You can flavor them however you like. I have a Pizzelle make that I bought from Taste Of Home, it makes Pizzelles, waffles and filled sandwiches. I made some rolled up cannoli shells, flat cookies and some dessert shells (add ice cream or fruit to them for a pretty dessert). You can also shape them into ice cream cones.
These tasted really good, I would say about 98% of what I remember from the gluten kind :O)
