Creating this delightful bread is as simple as gathering your ingredients and following these steps. Let’s get baking!

1. Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line it with parchment paper for easy removal.
2. In a large mixing bowl, whisk together the granulated sugar, brown sugar, and oil until well combined.
3. Add in the eggs, vanilla extract, lemon zest, and lemon juice. Mix until the batter is smooth and the ingredients are fully incorporated.
4. In another bowl, combine the flour, baking soda, baking powder, salt, and cinnamon (if using). Stir until well blended.
5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix—you want it to be moist, not tough!
6. Gently fold in the grated zucchini, ensuring it is evenly distributed throughout the batter.
7. Pour the batter into the prepared loaf pan. Smooth the top with a spatula.
8. Bake in the preheated oven for 50-60 minutes or until a toothpick inserted in the center comes out clean. The top should be golden and slightly domed.
9. Once baked, allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
