Preheat the oven to 350 F (165 C) and spray a 9X5 inch loaf pan with a non-stick cooking spray.
In a medium size bowl, whisk together the flour, cocoa powder, salt, baking soda and baking powder. Set aside.
In a separate large bowl, whisk together the eggs, butter, sugar and vanilla extract.
Slowly add flour mixture to the large bowl and stir until just combined. Be careful not to over mix.
Stir in the shredded zucchini and 3/4 cup of the chocolate chips.
Pour the batter into your greased loaf pan and sprinkle the remaining chocolate chips on top of the batter.
Bake for 50-60 minutes until a toothpick inserted into the middle of the bread comes out clean (try not to insert the toothpick into a melted chocolate chip to check for doneness).
Let cool on a wire rack for 10 minutes.
Carefully remove the bread from the pan and cool for an additional 15 minutes on the wire rack.
Then the bread is ready to slice, serve and enjoy!
