I love cinnamon in anything — babka, cookies, bread, muffins. You get the idea. I wanted a Pesach cookie with cinnamon in it as well and thus this recipe came about. They freeze beautifully, and, as with most Pesach baked goods, taste even better and crispier straight from the freezer. I love the combo and texture of nuts in them, too. They can even be used as a cracker of sorts to eat together with yogurt, cottage cheese, etc.
