1 Preheat the oven to 350°F (175°C), and butter a 4×8-inch loaf pan.
2 In a mixing bowl, mash the ripe bananas with a fork until completely smooth. Stir the melted butter into the mashed bananas.
3 Mix in the baking soda and salt. Stir in the sugar, beaten egg, and vanilla extract. Mix in the flour.
4 Pour the batter into your prepared loaf pan. Bake for 50 minutes to 1 hour at 350°F (175°C), or until a tester inserted into the center comes out clean.
5 Remove from oven and let cool in the pan for a few minutes. Then remove the banana bread from the pan and let cool completely before serving. Slice and serve. (A bread knife helps to make slices that aren’t crumbly.)
