01 - Preheat the oven to 350°F and grease a 9x5-inch loaf pan or line it with parchment paper.
02 - Whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg in a medium bowl.
03 - In a large bowl, whisk eggs, vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth.
04 - Stir the grated, squeezed-dry zucchini into the wet mixture until evenly blended.
05 - Add the dry ingredients to the wet ingredients and mix gently until just combined without overmixing.
06 - Gently fold in the semisweet chocolate chips until evenly distributed throughout the batter.
07 - Pour the batter into the prepared loaf pan, smooth the surface, and bake for 50 to 60 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
08 - Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack to cool completely. Slice before serving.
