Notes

  • The more ripe your bananas are the sweeter and more banana flavored these bars will be. 
  • If you don’t have buttermilk on hand, you can add a tablespoon of lemon juice to ¾ cup of milk. The acid in the lemon juice ferments the milk and acts as a raising agent.
  • Don't overmix the batter, the dry ingredients should be just combined.
  • Let the cake cool completely before cutting into bars.
Storage: Store chocolate chip banana bars in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 1 week, or in the freezer for up to 2 months.
