Preheat your oven to 350°F (175°C). Grease a loaf pan or line it with parchment paper for easy removal.
In a mixing bowl, mash the ripe bananas with a fork until smooth.
Add the granulated sugar, brown sugar, and melted butter to the mashed bananas. Mix well.
Beat in the egg and vanilla extract until fully combined.
Sprinkle the baking soda and salt over the mixture and mix thoroughly.
Gently fold in the all-purpose flour until just combined. Be careful not to overmix.
Stir in the chocolate chips until evenly distributed.
Pour the batter into the prepared loaf pan and spread it evenly.
Bake for 60 minutes, or until a toothpick inserted into the center comes out clean.
Allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
