01 - Preheat the oven to 350°F. Grease a 9x5-inch loaf pan with butter or cooking spray, then line with parchment paper for easy removal.
02 - In a large bowl, whisk together the mashed bananas, melted butter, and sugar until smooth and well combined.
03 - Beat in the eggs one at a time, then add the milk and vanilla extract. Mix until fully incorporated.
04 - In a separate medium bowl, whisk together the flour, baking soda, salt, and ground cinnamon until evenly distributed.
05 - Gently fold the dry ingredients into the wet mixture using a spatula. Mix only until just combined—do not overmix or the bread will become tough.
06 - Fold in chopped nuts or chocolate chips if desired, distributing evenly throughout the batter.
07 - Pour the batter into the prepared loaf pan and smooth the top with a spatula for even baking.
08 - Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs. The top should be golden brown.
09 - Let the bread cool in the pan for 10 minutes, then carefully remove and transfer to a wire rack. Cool completely before slicing for best results.
