Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 4x8-inch loaf pan.
Mix Wet Ingredients: In a mixing bowl, mash the overripe bananas with a fork until smooth. Stir in the melted butter.
Combine the Dry Ingredients: Mix in the baking soda and salt, followed by the sugar, beaten egg, and vanilla extract. Blend well.
Add the Flour: Gently fold in the flour until just combined. Be careful not to overmix.
Add the Chocolate: Finally, fold in the chocolate chips, distributing them evenly throughout the batter.
Pour and Bake: Pour the batter into the prepared loaf pan and bake for 60-65 minutes, or until a toothpick inserted in the center comes out clean.
Cool and Slice: Let the bread cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely before slicing.
