Preheat the oven to 350 F. Grease a 9 x 5-inch loaf pan and line with parchment paper.

Mash the bananas in a large mixing bowl.

To the mashed bananas, add the sugar, melted butter, and eggs one at a time, and then add the vanilla extract. Use a handheld mixer to mix on low until combined.

In a separate mixing bowl, combine the flour, baking powder, baking soda, and salt.

Add dry ingredients to wet ingredients. Mix on low until combined, being careful not to overmix.

Pour batter into the prepared loaf pan.

Bake for 50-55 minutes until a toothpick or skewer inserted into the center comes out clean or with just a few crumbs.

Remove pan from the oven and allow bread to cool in the pan on a wire rack for about 5 minutes. Then remove bread from the pan and let loaf cool completely before slicing.
