Making Lemon Zucchini Sheet Cake is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, and salt.
3. Combine Wet Ingredients: In another bowl, mix the grated zucchini, vegetable oil, eggs, lemon zest, lemon juice, and vanilla extract until well combined.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Avoid overmixing.
5. Pour Batter: Pour the batter into the prepared baking pan and spread it evenly.
6. Bake: Place in the preheated oven and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
7. Cool: Once baked, remove from the oven and allow the cake to cool in the pan for 15-20 minutes. Then transfer to a wire rack to cool completely.
8. Dust with Powdered Sugar: Before serving, dust the top with powdered sugar for an elegant finish, if desired.
