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, mash the bananas until smooth. Whisk in eggs, oil or melted butter, sugar, and vanilla extract until well combined.
03 - In a separate bowl, whisk together flour, baking soda, and salt.
04 - Add the dry ingredients to the wet mixture and stir gently until just combined. Do not overmix.
05 - Fold in chocolate chips and nuts if using.
06 - Pour the batter into the prepared loaf pan and smooth the top.
07 - Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
08 - Cool in the pan for 10 minutes, then transfer the loaf to a wire rack to cool completely before slicing.
