Creating Blueberry Zucchini Bread is easy and rewarding! Just follow these simple steps:

1. Preheat your oven: Set your oven to 350°F (175°C) and grease a 9×5-inch loaf pan or line it with parchment paper.
2. Prepare the dry ingredients: In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon.
3. Mix the sugars and wet ingredients: In a large bowl, combine the granulated sugar, brown sugar, and vegetable oil, mixing thoroughly. Add the eggs and vanilla extract, and beat until well combined.
4. Incorporate the zucchini: Gently fold the grated zucchini into the wet mixture.
5. Combine mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to overmix; a few flour streaks are okay.
6. Add blueberries: Gently fold in the blueberries and nuts (if using), ensuring an even distribution.
7. Pour into the pan: Transfer the batter into the prepared loaf pan, using a spatula to smooth the top.
8. Bake: Place in the preheated oven and bake for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Once baked, remove from the oven and let it cool in the pan for 10-15 minutes. Then transfer it to a wire rack to cool completely.
10. Slice and enjoy: Once cool, slice the Blueberry Zucchini Bread and serve. The joy is in each moist and flavorful bite!
