  • 1/2 cup butter room temperature
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar
  • 1 egg room temperature
  • 1 1/2 teaspoon vanilla
  • 1 cup fresh sourdough start or light sour cream- room temperature
  • 2 overripe bananas mashed (approx 1 cup)
  • 2 cups flour
  • 1 teaspoon sea salt
  • 1/2 teaspoon baking soda
  • 1/2 cup mini semi-sweet chocolate chips


  • Preheat oven 350 degrees F.
  • Coat 9x5 pan with cooking spray; set aside.
  • In a large mixing bowl cream butter.
  • Add sugars and cream 3-4 minutes until light and fluffy.
  • Add egg; mix 2 minutes.
  • Add vanilla, sourdough start, and mashed banana; mix to incorporate.
  • In a separate bowl combine flour, sea salt, and baking soda; use a whisk to combine.
  • Add flour mixture all at once to wet ingredients; mix until 80% incorporated.
  • Add mini semi-sweet chocolate chips; gently mix with spatula to combine.
  • Do not over mix- a few lumps are okay.
  • Evenly spread batter into prepared pan.
  • Bake 45-60 minutes until a toothpick inserted in the center removes clean.
  • If at 45 minutes the top of the loaf looks very browned, set a piece of foil over the top to protect over browning. ( I needed to do this)
  • Cool on rack for 10 minutes, turn out and complete cooling.
  • Enjoy!
