Quite some time ago, we built a zucchini cookbook. (Yeah, it's a little dated but the recipes are great. And it's free.)
The cover recipe, the zucchini cookie recipe, is worth the book. But then, so is the zucchini bread recipe.
Some of the recipes call for cinnamon chips. It's a little risky shipping cinnamon chips this time of year but if you want to, they're half price!
