Preheat oven to 350 degrees F.
Grease a 4x8 inch loaf pan with cooking spray or oil.
Peel bananas and add them to a large bowl. Mash with a fork.
Add everything except for the flour and chocolate chips to the mashed bananas. Beat with an electric mixer.
Slowly add the flour to the banana mixture, mixing on low speed just until combined.
Pour batter into loaf pan. Sprinkle chocolate chips on unbaked bread, pushing in slightly with oon or finger tops.
Bake for 45 minutes, or until golden and a toothpick inserted in the middle comes out clean. Let cool for 5-10 minutes before removing from pan.
