Chocolate Zucchini Cake

This chocolate cake is a great way to eat zucchini!  It is a very tasty cake.  I tried it once with all whole wheat flour and agave nectar for the sugar--ummmm, don't waste your time.  Hubby actually said it was worthless.  I have to admit it was extremely heavy!  I will work on substitutions and try again some other day!  Enjoy this one!
