Preheat your oven to 350°F (175°C).
Grease a 9x5-inch loaf pan.
In a large mixing bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and chocolate chips.
In another bowl, beat the eggs, vegetable oil, both sugars, and vanilla extract until well combined.
Fold the wet ingredients into the dry ingredients gently, and then add the shredded zucchini.
Stir until just combined without overmixing.
Pour the batter into the prepared loaf pan and sprinkle the coarse sugar on top.
Bake for 50 to 60 minutes until a toothpick inserted in the center comes out clean.
