Preheat oven to 350F. Grease a 9x5x3 loaf pan.
Shred zucchini. Set aside.
In large bowl, stir together flour, cocoa, BP, BS, salt and cinnamon. Add chocolate chips. Set aside.
In a medium bowl beat egg replacement mixture with oil, sugars and vanilla.
Fold in the zucchini.
Fold in the flour mixture just until moistened.
Spread evenly in loaf pan and bake 55 - 65 minutes or until cake tester inserted in middle comes out clean of batter (chocolate chips will remain soft and stick to tester).
Cool in pan on wire rack for 10 minutes.
Remove from pan and cool completely.
Loaf can be stored at room temperature for several days or frozen up to a month.
