shred or grate zucchini and set aside
Preheat oven to 325º
lightly grease a loaf pan or use cooking spray, set aside
In a large mixing bowl, whisk sugar, eggs, oil, and vanilla together and set aside
in a medium bowl stir together flour, baking soda, salt, and cinnamon, and mix together
add the dry ingredients to the wet ingredients and stir to combine, just until the flour mixture is incorporated
pour off any excess water in the zucchini bowl
Add zucchini, and stir until fully incorporated, don't overmix quick breads
Stir in chocolate chips
Pour into the prepared pan
Sprinkle with extra chocolate chips if desired
Bake in center of oven for 75 minutes, until a toothpick inserted into the center of the loaf comes out clean if you can manage to avoid a chocolate chip
Remove from oven and let cool 10 minutes on a cooling rack
Then turn it out of the pan onto the cooling rack and let cool completely
You can slice it while it's warm and slather it with butter if you want to, the loaf won't slice as cleanly when sliced warm though
