Preheat your oven to 350°F (175°C).
In a large mixing bowl, mash the ripe bananas until smooth.
Stir in the melted butter into the mashed bananas until combined.
Add the granulated sugar, egg, and vanilla extract, mixing until just combined.
In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually fold the dry ingredients into the banana mixture until just combined.
Gently fold in the chocolate chips.
Pour the batter into a greased 9x5-inch loaf pan.
Bake for 60-65 minutes, or until a toothpick comes out clean.
Allow the bread to cool in the pan for 10 minutes before transferring to a wire rack.
Slice and enjoy your chocolate chip banana bread.
