Here's one more thing to do with your extra zucchini this year. This doesn't look like your typical brownie, but it is still delicious. As I was baking it, I thought I'd be disappointed, but the moistness and flavor are awesome!! I found this on Cooks.com.
3 c flour
4 T cocoa
1/2 t salt
1 t soda
1 t cinnamon (I used a little less)
1 c oil
1 3/4 c sugar
2 eggs, slightly beaten
1 t vanilla
1/2 c buttermilk (I was out, so I used some vinegar in whole milk)
2 c grated zucchini, squeeze out moisture
1 c chocolate chips
3/4 c walnuts
Combine first 5 dry ingredients, and set aside. Beat sugar and eggs til fluffy. Add oil and vanilla. Beat til fluffy. Mix in zucchini. Then add flour mixture and buttermilk alternating. Add chips and walnuts. Bake at 350 for 25-30 minutes in a 10x15 (I think that is jelly roll size) pan.
I omitted walnuts and used bittersweet chocolate chunks. MMMMMM!
I also misread the pan size and used a 9x13. (I looked at about 20 recipes before deciding on this one, and they all had different pan sizes!!) Don't do that. The middle didn't get done, and I had to chuck that part. Whoops!
