Preheat your oven to 350°F (175°C). Grease a 9x5-inch loaf pan with butter, then dust it lightly with flour.

In a large mixing bowl, mash the three ripe bananas with a fork until mostly smooth, leaving a few small lumps for texture.

Add the slightly cooled melted butter to the mashed bananas, stirring until well combined, then add the sugar and mix thoroughly.

Add the eggs one at a time, mixing thoroughly after each addition.

Gently fold in the flour, baking soda, and salt until no dry streaks remain.

Pour the batter into the prepared loaf pan, smoothing the top with a spatula.

Bake for 50-55 minutes, checking for doneness with a toothpick.

Once baked, let your banana bread cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
