Preheat oven to 350 degrees F. Grease two 9-inch loaf pans with shortening and coat with cocoa powder. Set aside.
Sift together flour, cinnamon, salt, baking soda and cocoa powder.
In a separate bowl, lightly beat eggs. Add both sugars and mix until well incorporated. Slowly pour in vegetable oil while mixing. Add vanilla, coffee, sour cream, and mix.
Add in dry ingredients, mixing lightly between each addition. Lastly, add zucchini and mix until just incorporated. Optional: add 1 cup chocolate chips that have been mixed with 1 tablespoon flour.
Pour into prepared loaf pans. Bake for 50-60 minutes or until toothpick comes out clean.
Let cool while preparing icing. Remove from pans after 10 minutes.
Mocha Glaze

In a separate bowl, mix cocoa powder and coffee. Pour into powdered sugar mixture and beat until smooth.
Once the bread is cooled, drizzle over bread as desired. Let bread sit to give glaze time to set.
