01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan with butter or cooking spray, or line with parchment paper for easy removal.
02 - In a large mixing bowl, whisk mashed bananas with melted butter until completely smooth and incorporated.
03 - Stir in granulated sugar, brown sugar, eggs, and vanilla extract. Mix thoroughly until the mixture is uniform and slightly thickened.
04 - In a separate medium bowl, sift together flour, baking soda, and salt to ensure even distribution.
05 - Gradually add the dry ingredients to the wet mixture. Stir gently with a spatula or wooden spoon until just combined—some small lumps are acceptable. Do not overmix.
06 - Add chocolate chips to the batter, folding gently to distribute evenly. Reserve a small handful to sprinkle on top before baking.
07 - Pour batter into prepared loaf pan, spreading evenly with a spatula. Scatter reserved chocolate chips across the surface for visual appeal.
08 - Bake for 50 to 60 minutes. Check for doneness by inserting a toothpick into the center—it should emerge with a few moist crumbs but not wet batter.
09 - Allow the bread to cool in the pan for 10 minutes. Carefully remove and transfer to a wire rack to cool completely before slicing.
