01 - Preheat the oven to 350°F. Grease a 9x5-inch loaf pan or line with parchment paper.
02 - In a medium mixing bowl, whisk together the flour, baking soda, cinnamon, and salt until thoroughly blended.
03 - In a large bowl, cream the softened butter with granulated sugar using an electric mixer or whisk until the mixture is light and fluffy.
04 - Add eggs one at a time, mixing well after each addition. Blend in vanilla extract and mashed bananas until smooth.
05 - Alternate adding the dry ingredients and milk to the banana mixture, beginning and ending with the dry ingredients. Mix gently just until incorporated.
06 - Fold in chopped nuts or chocolate chips if desired, ensuring even distribution.
07 - Pour the batter into the prepared loaf pan and smooth the surface with a spatula.
08 - Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean.
09 - Let the bread cool in the pan for 10 minutes, then remove to a wire rack to cool completely before slicing.
