Step 1

Preheat oven to 350°F. Lightly grease a 9x5-inch loaf pan with butter or cooking spray.

Step 2

In a large mixing bowl, mash the bananas with a fork until smooth. Stir in the sugar, egg, melted butter and vanilla extract.

Step 3

In another bowl, whisk together the flour, baking powder, baking soda and salt.

Step 4

Add the dry ingredients to the wet banana mixture and mix until combined.

Step 5

Pour the batter into the prepared loaf pan. Bake for 50 minutes to 1 hour or until a toothpick inserted into center of the loaf comes out clean.

Step 6

Remove from oven and let cool in the pan for a few minutes. Then remove the banana bread from the pan and allow it to cool completely before slicing and serving.
