In a large mixing bowl, place the eggs, sugar and oil. Whisk these together until smooth.
Add flour, baking soda, baking powder, salt and cocoa powder to the egg mixture; mix these ingredients very well.
Add the drained/pressed grated zucchini, along with the chocolate chips and the dark chocolate pieces to the batter. Stir well by hand until ingredients are completely blended.
Take the cooking spray and spray a standard sized muffin tins (liners are optional...I didn't use them). Fill the muffin holders about 3/4 of the way to the top with the batter. There is enough batter to yield approx. 30 muffins. Sprinkle a few extra chocolate chips on top before baking. (this is optional)
Bake the muffins at 350 degrees for 15-20 minutes or until the top springs back when touched. Remove muffins from oven and cool on a wire rack. Dust with sifted powdered sugar for a nice presentation. Serve and enjoy!
That's a LOT of muffins! You can freeze extra muffins for another day, or easily cut the recipe in half and make 15 muffins.
