I LOVE the new recipe book I got! It's called Now Eat This, by Rocco Dispirito.
They've got recipes for chocolate chip cookies made using white kidney beans and brownies made using black beans. Now, I've heard of this type of exchange (beans instead of butter, etc.) before and I've always wanted to try it and see if it really is any good. Well I am now! Tonight, I'm going to try making the Triple Chocolate Chocolate Chip Cookies. I've got my cannellini beans soaking at home as we speak! This recipe makes 20 cookies. The stats are 45 calories and 1.4 grams of fat per cookie (I do wonder how big these are, we'll see) vs. the usual full-fat CC cookie stats of ~200 calories and 10 grams of fat per cookie.
Hopefully the cookies don't require a side of Gas-X! (because of all the beans, haha!)
