Preheat Oven: Set your oven to 350°F (175°C).
Prepare Pan: Grease a 9x5-inch loaf pan or line it with parchment paper.
Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, and salt.
Combine Wet Ingredients: In a large bowl, mix the mashed bananas with the melted butter until well combined.
Add Sugar and Egg: Stir in the sugar, beaten egg, and vanilla extract until smooth.
Combine Wet and Dry Mixtures: Gradually add the dry ingredients to the wet mixture, stirring gently until just combined.
Fold in Chocolate Chips: Gently fold the chocolate chips into the batter.
Pour into Pan: Transfer the batter into the prepared loaf pan, smoothing the top.
Bake: Place the pan in the preheated oven and bake for 60-65 minutes, or until a toothpick inserted into the center comes out clean.
Cool: Remove from the oven and let the bread cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing.
