Zucchini Chip Snack Cake

We have two zucchini plants in our garden this year, so we arent hugely overrun with zucchini, but we surely have plenty. One of my favorite things to make with all our zucchini is this cake. Its mildly chocolately and very moist. Yum!
It makes a nice big 9x13 and freezes very well, but the recipe can be halved very easily and made in a 9x9 also. I have never made it without the chocolate chips, but I imagine it would be delicious that way also. I have a couple of hugely over grown zucchini's (I used only half of one for these 2 cups in this recipe!!) I plan on testing out whether this would make a good bread without the chocolate chips and maybe even without the cocoa.
