Preheat your oven to 350°F (175°C) and grease a loaf pan.

Mash the ripe bananas in a bowl until smooth.

In another bowl, whisk together melted butter, eggs, and vanilla extract until well combined.

In a separate bowl, mix together flour, sugar, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture while stirring gently until just combined.

Pour the batter into the prepared loaf pan and bake for 50-60 minutes or until a toothpick inserted comes out clean.

Allow to cool before slicing and serving.
