01 - Preheat the oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper for easy removal.
02 - In a large bowl, whisk together the mashed bananas, melted butter, and sugar until smooth.
03 - Add the eggs, milk, and vanilla extract, mixing until well combined.
04 - In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
05 - Gently fold the dry ingredients into the wet mixture until just combined. Do not overmix.
06 - Fold in nuts or chocolate chips, if using.
07 - Pour the batter into the prepared loaf pan and smooth the top.
08 - Bake for 50 to 60 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
09 - Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
