Preheat the oven to 425 degrees Fahrenheit.
Line a muffin tray with 12 liners and set aside. Grate the zucchini and set aside. Don't squeeze out the liquid. Whisk together all wet ingredients.
Whisk in the dry ingredients making sure to spoon and level the flour and cocoa powder.
Fold in the zucchini and chocolate chips.
Scoop the batter into the muffin tray, filling each pretty close to the top for nice round muffin tops. Add some extra chocolate chips on top.
Bake for 5 minutes at 425, then decrease the temperature to 350 and bake an additional 14-18 minutes or until a toothpick comes out clean with a few moist crumbs. Mine are usually good at 15, but all ovens are different.!
Let cool in the tray for about 10 minutes, then remove and let finish cooling on a cooling rack.
