Creating Luscious Lemon Zucchini Bread is a straightforward task when you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan.
2. Mix Dry Ingredients: In a large mixing bowl, sift together the flour, baking soda, baking powder, salt, and cinnamon.
3. Beat Eggs: In a separate bowl, beat the eggs until frothy.
4. Combine Wet Ingredients: Add the granulated sugar, vegetable oil, vanilla extract, lemon zest, and lemon juice to the eggs, stirring until well combined.
5. Combine Mixtures: Gradually merge the wet ingredients into the dry ingredients, stirring until just combined. Do not overmix.
6. Add Zucchini: Fold in the grated zucchini and walnuts or pecans if using.
7. Pour into Pan: Pour the batter into the prepared loaf pan, smoothing the top lightly.
8. Bake: Place the pan in the preheated oven and bake for 40-50 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove it from the oven and allow the bread to cool in the pan for about 15 minutes. Transfer it to a wire rack to cool completely.
10. Dust: If desired, dust the top with powdered sugar for a decorative touch before slicing.

These simple steps will lead you to creating Luscious Lemon Zucchini Bread effortlessly.
