Preheat oven to 325 degrees. Spray two 9? x 5? bread pans with nonstick spray.
In a large mixing bowl, combine zucchini, oil, eggs, and vanilla. Mix thoroughly.
Beat sugar into mix until it is thoroughly creamed.
Once liquids and sugar are well mixed, add flour, baking soda, baking powder, salt, and cinnamon. Mix until batter is well blended and even in texture. The batter should be smooth, outside the zucchini shreds. If it’s not, add a little juice from the zucchini.
Pour batter evenly into pans. As you can see I added chocolate chips to one of the loaves.
Bake for approximately 1 hour, or until bread is brown and springs back when gently pressed in the middle.
