Preheat oven to 350 F degrees.
Grease a loaf pan and set aside.
In a medium-size microwavable bowl, microwave the butter until melted, about 40-60 seconds.
Mash in the bananas (the texture should be smooth) with the melted butter.
Mix in the sugar and egg.
Stir in the remaining dry ingredients (all purpose flour, baking soda and salt) and fold in the chocolate chips. Make sure not to over-mix.
Pour the batter into the prepared loaf pan.
Bake the mixture in the oven for about 45-55 minutes until golden brown. Insert a knife in the middle, and if it comes out clean, then the banana bread is done and ready.
Immediately, remove the bread from the pan. Do not allow the bread to cool in the pan or the bread will be turn soggy.
