Preheat oven to 350 degrees.

Mash the bananas in a small bowl until they are smooth.

In a stand mixer or with a hand mixer, mix softened butter and sugars until creamed and fluffy. Then add mashed bananas, eggs and vanilla extract. Mix well until thoroughly incorporated.

In a separate bowl whisk together flour, baking soda, baking powder, and salt. Then slowly add to the wet mixture and mix/stir until thoroughly combined.

Fold in 3/4 cup of the chocolate chips into the batter, and then pour into a prepared loaf pan. Sprinkle the remaining 1/4 cup of chocolate chips on top.

Bake for 50-60 minutes, checking for doneness with a knife or toothpick inserted into the center (it should come out clean).

Cool the bread in the pan for 20 minutes before removing and transferring to a wire rack to finish cooling completely.
