Preheat the oven: Set your oven to 350°F (175°C) and grease or line your loaf pan with parchment paper.
Prepare the bananas: In a large bowl, mash the bananas with a fork or potato masher until they are smooth but still slightly chunky. If you like your banana bread with a bit more texture, leave a few larger banana chunks.
Mix dry ingredients: In a medium bowl, whisk together the flour, baking soda, and salt.
Combine wet ingredients: In another bowl, whisk together the melted butter, eggs, and vanilla extract until smooth.
Mix everything together: Add the mashed bananas to the wet ingredients and stir well. Gradually fold in the dry ingredients, mixing until just combined. Be careful not to overmix the batter, as this can result in a dense loaf.
Bake the bread: Pour the batter into the prepared loaf pan and spread it evenly. Bake for 60-70 minutes or until a toothpick inserted into the center comes out clean.
Cool and serve: Once baked, remove the bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a cooling rack to cool completely before slicing.
