Preheat oven to 350°F. Grease one 9x5 loaf pan (we used a metal pan).
In a mixer, combine oil, sugars, and vanilla. Mix in eggs and shredded zucchini.
In a separate bowl, mix flours, cocoa powder, baking soda, baking powder, salt, and cinnamon. Slowly mix this dry mixture into your wet mixture. Beat until combined. Mix in chocolate chips.
Move the batter to your prepared loaf pan, and bake at 350°F for 55-65 minutes, or until a toothpick comes out clean when inserted into the center. Remove from oven and cool in pan for 10 minutes before cooling on a wire rack.
Freezer Instructions
Freeze for Later: After bread is baked, let cool completely. Slice the bread but keep it in the form of a loaf. By slicing it, you can thaw out one or two pieces instead of the whole loaf. Wrap loaf in saran wrap and then in foil. Store in freezer for up to 3 months.Prepare From Frozen: Thaw individual slices of bread in refrigerator or microwave.
Notes/Tips
We tested this bread in a metal loaf pan. If using glass or ceramic, bake time may be a little shorter or longer so keep an eye on it.
