Preheat oven to 350°F (175°C). Grease or line a standard loaf pan with parchment paper.
Mix dry ingredients: In a large mixing bowl, whisk together flour blend, baking powder, baking soda, cinnamon, and salt.
Prepare wet ingredients: In another bowl, beat the eggs lightly. Add sugar, oil, and vanilla; whisk until combined.
Combine: Add the wet mixture to the dry ingredients, stirring gently until just combined.
Add zucchini: Fold in shredded zucchini, ensuring even distribution without overmixing.
Bake: Transfer batter to the prepared loaf pan. Bake for 50–60 minutes, or until a toothpick inserted in the center comes out clean.
Cool: Let the bread rest in the pan for 10 minutes before transferring to a wire rack to cool completely.
