Creating Luscious Lemon Zucchini Bread is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon.
3. Combine Sugars and Eggs: In a large bowl, mix the granulated sugar, brown sugar, and eggs until smooth and creamy.
4. Incorporate Oil and Flavorings: Stir in the vegetable oil, lemon zest, lemon juice, and vanilla extract to the sugar-egg mixture, blending well.
5. Add Zucchini: Gently stir in the grated zucchini until evenly distributed throughout the batter.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Avoid overmixing to keep the bread tender.
7. Pour into Pan: If using nuts, gently fold them into the batter before pouring it into the prepared loaf pan.
8. Bake: Place the pan in the preheated oven and bake for 55-60 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Allow the bread to cool in the pan for 15 minutes before transferring it to a wire rack to cool completely.
