01 - Preheat the oven to 350°F. Grease a 9x5-inch loaf pan or line with parchment paper.
02 - In a medium bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, and nutmeg until well blended.
03 - In a large bowl, beat the eggs, vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth and fully incorporated.
04 - Fold the grated zucchini into the wet mixture until evenly distributed throughout.
05 - Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix to avoid tough bread.
06 - Gently fold in the chocolate chips until evenly distributed in the batter.
07 - Pour the batter into the prepared loaf pan, smoothing the top evenly with a spatula.
08 - Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
09 - Allow the bread to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
