This is my Zucchini recipe that I used.
1 C oil
2 C sugar
Add 3 C flour, 1t baking soda, 1 t baking powder, 1 t cinnamon 1 t salt, 1 t vanilla. Add 2 C grated zucchini. For one loaf of regular and one loaf chocolate I added 3 T cocoa after I had poured the first loaf into the greased pan. For two chocolate loaves I added 6 T to the whole mix. Bake at 350 for 50-60 minutes.
