Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
Step 2: Grease a 9x5 inch loaf pan with cooking spray or butter, or line it with parchment paper.
Step 3: In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, ground cinnamon, and salt. Set aside.
Step 4: In another bowl, beat the eggs, then mix in the granulated sugar and vegetable oil until well combined. Stir in the mashed bananas and shredded zucchini.
Step 5: Slowly add the dry ingredients to the wet mixture, using a rubber spatula to fold them together gently, being careful not to overmix.
Step 6: Fold in the chopped pecans until evenly distributed throughout the batter.
Step 7: Pour the batter into the prepared loaf pan, smoothing the top with your spatula.
Step 8: Place the loaf pan in the preheated oven and bake for 60-70 minutes, or until a toothpick inserted into the center comes out clean.
Step 9: Once baked, remove the bread from the oven and allow it to cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely.
