Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Pour the batter into the prepared loaf pan.
Bake for 55-65 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the banana bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
Notes
You can add chocolate chips, nuts, or a sprinkle of cinnamon to the batter for extra flavor. Ensure bananas are very ripe for the best sweetness and moisture.
