Can you use underripe bananas?

It’s best to use ripe or overripe bananas in these bars. They will be much sweeter and more flavorful than underripe. They will also be easier to mash.

How long do they keep?

Once the cake is cooled and cut into bars, transfer to an airtight container. They will keep well at room temperature for up to 3 days and will keep for up to 7 days in the fridge. They make a great addition to daily lunchboxes!

Can you freeze them?

Yes! You can freeze these banana bars either in the dish, or wrap them individually and place in freezer bags. You can thaw them at room temperature or in the fridge.

Recipe Notes and Tips

• 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 over mix the batter, the dry ingredients should be just combined.
• Let the cake cool completely before cutting into bars.
