Preheat the Oven: Set your oven to 350°F (175°C). Prepare a 9x5 inch loaf pan by greasing it with cooking spray or lining it with parchment paper for easy removal.
Prepare the Zucchini: In a medium mixing bowl, combine the grated zucchini with a pinch of salt. Allow it to sit for 5-10 minutes. This step helps to release excess moisture. After resting, gently squeeze the zucchini to remove any additional liquid before setting aside.
Mix Dry Ingredients: In a large bowl, use a whisk to combine the all-purpose flour, whole wheat flour, baking soda, baking powder, salt, and ground cinnamon. Ensure that these ingredients are well incorporated for an even bake.
Combine Wet Ingredients: In a separate mixing bowl, thoroughly mix together the granulated sugar, brown sugar, and vegetable oil until smooth. Then, add the eggs one at a time, mixing well after each to ensure they are fully integrated. Stir in the vanilla extract to add depth of flavor.
Blend Ingredients: Gradually add the dry flour mixture to the wet mixture. Use a spatula or wooden spoon to stir gently until just combined. Be cautious not to overmix—the batter should still have some lumps for a tender texture.
Incorporate Zucchini & Add Ins: Fold in the prepared zucchini, chocolate chips, and nuts (if desired) using a gentle motion. Again, avoid overmixing; you want a uniformly mixed batter without overworking it.
Transfer to Pan: Pour the batter into the prepared loaf pan, using a spatula to smooth out the top for even baking.
Bake the Bread: Place the loaf pan in the preheated oven and bake for 50-60 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean or with a few moist crumbs.
Cool Down: Once baked, take the bread out of the oven and let it cool in the pan for about 10 minutes. After that, carefully transfer it to a wire rack for complete cooling.
Notes
Serve warm with powdered sugar or butter for an extra treat.
