Step 1

Preheat oven to 350 degrees. Spray a 9x5-inch loaf pan with nonstick cooking spray. Set aside.

Step 2

In a large bowl, whisk together flour, cinnamon, baking powder, baking soda and salt. In a medium bowl, whisk together melted butter, sugar, egg and vanilla extract. Add the shredded zucchini with a spatula until combined. Pour the wet mixture into the dry mixture and mix until just combined. Fold in 3/4 cup of the chocolate chips.

Step 3

Pour the batter into the prepared pan. Smooth the top and then sprinkle with the remaining chocolate chips. Bake for 45-50 minutes or until a toothpick inserted in the center of the loaf comes out mostly clean. If your loaf seems to be browning too quickly, just tent with foil. Remove from the oven and cool on a wire rack.
