Mix first four ingredients together. Then mix in zucchini, followed by remaining ingredients. Put in two greased and floured loaf pans. I like to add a light coating of brown sugar on top of the regular bread. Bake at 350 for 1 hour.
Notes
(To make the bread chocolate - decrease cinnamon to 1 tsp and add 1/2 cup cocoa powder and you can add a cup of chocolate chips if desired. Make sure to toss the chips with a little flour before adding to the mixture. This prevents them from sinking to the bottom of the bread.)
