1 large egg beaten
3-4 ripe bananas mashed
2 cups all-purpose flour or whole wheat flour
1 teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
1 teaspoon vanilla
1 cup dark chocolate chips
1. Preheat oven to 350 degrees F. Place a folded piece of parchment paper in a loaf pan and spray with cooking spray and set aside.
2. In large bowl, cream butter and sugar together for about 2 minutes until well combined. Add the egg and the mashed bananas. Mix for 20 seconds, scraping down the sides of the bowl.
3. Add flour, baking soda, baking powder, salt and vanilla. Mix until well combined. Fold in the chocolate chips.
4. Pour the mixture into the loaf pan. Bake for 55-65 minutes until a knife inserted in the center of the loaf comes out clean. Let cool for at least 30 minutes before serving.
