Preheat the oven to 350 F.
Grate the zucchini in a bowl and set aside.
Combine dry ingredients in another mixing bowl.
In a separate bowl, beat eggs; add oil, sugar, vanilla, and zucchini in with the liquid.
Add in the dry ingredients and beat on low with a mixer.
Fold in chocolate chips and pour into a 9 x 5 inch loaf tin (greased or lined with parchment paper). Top with more chips if desired. Make a small cut lengthwise about ¼ inch deep in the center of the bread.
Bake for about 55 minutes minutes OR until the toothpick inserted into the center comes out clean. The bread should be still moist inside. It may need 5-10 extra minutes, depending on your oven.
Let the bread sit in the loaf tin for 10 minutes before taking it out and leaving on a wire rack to cool completely. Enjoy!
