01 - Preheat the oven to 350°F. Grease and flour a 9x5-inch loaf pan or line with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, cinnamon, and salt until evenly combined.
03 - In a large bowl, beat eggs, vegetable oil, granulated sugar, brown sugar, and vanilla extract until smooth.
04 - Add the dry mixture to the wet ingredients and stir gently until just combined.
05 - Carefully fold grated zucchini and chocolate chips into the batter, avoiding overmixing.
06 - Pour batter into the prepared pan and smooth the surface. Bake for 50 to 55 minutes until a toothpick inserted near the center comes out clean.
07 - Allow to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
