Set your oven to 350°F or 180°C. Lightly grease a standard loaf pan or line it with parchment paper.

In a large mixing bowl, mash the bananas with a fork until smooth. Lumps are fine, but the more mashed they are, the more moisture they’ll bring.

Pour the melted butter into the mashed bananas. Stir until fully combined and glossy.

Add the brown sugar, egg, and vanilla extract. Mix until everything looks blended and smooth.

Sprinkle in the baking soda and salt first, then add the flour. Gently stir everything together just until you no longer see streaks of flour. Do not overmix or the bread may turn out dense.

Add most of the chocolate chips and gently fold them into the batter. Leave a few chips aside for sprinkling on top.

Pour the batter into the prepared pan. Use a spatula to even out the top. Add the remaining chocolate chips on top.

Place in the oven and bake for 50 to 60 minutes. The top should be golden brown and a toothpick inserted in the center should come out with a few moist crumbs.

Let the loaf cool in the pan for 10 to 15 minutes. Then transfer it to a wire rack and cool fully before slicing. This helps lock in the moisture and makes cutting easier.
