Creating the amazing One Bowl Chocolate Zucchini Bread is straightforward if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, salt, and cinnamon until well combined.
3. Add Wet Ingredients: In the same bowl, add the eggs, grated zucchini, vegetable oil, and vanilla extract. Stir until just combined; do not overmix.
4. Fold in Add-Ins: If desired, gently fold in the chocolate chips and nuts for added texture and flavor.
5. Pour Batter: Pour the batter into your prepared loaf pan, smoothing the top with a spatula.
6. Bake: Place the loaf in the preheated oven and bake for 50–60 minutes or until a toothpick inserted in the center comes out clean.
7. Cool: Remove from the oven and allow the bread to cool in the pan for about 10–15 minutes. Then transfer to a wire rack to cool completely.

These clear steps ensure your One Bowl Chocolate Zucchini Bread is a success every time!
