Preheat your oven to 350°F (175°C) and grease a 9x5-inch loaf pan.
In a large bowl, mash the ripe bananas until smooth, leaving a few lumps for texture.
In a separate bowl, whisk together the melted butter, granulated sugar, eggs, and vanilla extract until well combined.
In another bowl, mix the all-purpose flour, baking soda, and salt.
Gradually mix the dry ingredients into the wet ingredients, stirring gently until just blended.
Pour the batter into the prepared loaf pan, spreading it evenly.
Bake for 60-65 minutes, or until a toothpick inserted into the center comes out clean.
Allow the banana bread to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
