Preheat oven to 350 degrees.

In a large bowl use a hand mixer to mix the melted butter and brown sugar until sugar is dissolved.

Mash bananas with a fork and beat in with egg and vanilla extract.

In a medium bowl, whisk together flour, baking soda, baking powder, and salt.

Combine wet dry mixtures.

Fold in most of the chocolate chips, reserving a small handful.

Pour batter into a greased loaf pan. Sprinkle remaining chocolate chips on top.

Bake for 45 minutes. Allow bread to cool, then it will slip right out of the pan.
