Preheat your oven to 350°F (175°C) and grease a 4×8 inch loaf pan.

In a mixing bowl, mash the ripe bananas with a fork until mostly smooth. You’ll want some lumps for added texture.

Stir the melted butter into the mashed bananas until well combined.

Mix in the sugar, beaten egg, and vanilla extract until blended thoroughly.

Sprinkle the baking soda and salt over the mixture, then mix in the flour until just incorporated.

Gently fold in the chocolate chips, making sure they’re evenly distributed throughout the batter.

Pour the batter into your prepared loaf pan and bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean.

Let it cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely before slicing.
