Preheat the oven to 350°F. Spray a 5x9-inch loaf pan with nonstick cooking spray or line it with parchment paper.
Mash the bananas in a large mixing bowl until mostly smooth.
Stir in the melted butter, egg, sugar, vanilla, baking soda, and salt until well combined.
Add the flour and stir just until incorporated. Do not over mix.
Pour the batter into the prepared loaf pan.
Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean. Begin checking for doneness around 50 minutes, as baking times may vary.
Let the bread cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.
