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.

Nutrition Information
Could you make these into muffin/cupcakes? If so does the baking time need to change?
Yes, we would start checking them at about 15 minutes!
DELICIOUS & easy to make!! Will make again!! Yum.
These look amazing! We don’t use cow’s milk, do you know of anything else we can substitute for the buttermilk? We typically drink oat, almond, or coconut milk, so I’m unsure if the vinegar trick will work on those.
I can’t wait to figure out a way to substitute so we can make these!
You can try a vegan sour cream?
Yes, you can add lemon juice to oat milk to substitute buttermilk and it works just fine. 1tsp lemon juice in half cup of oat milk :)
very good.i used half the sugar and added an extra banana. i am always looking for recipes to use up old bananas. Hate to waste food. This was perfect!
Thanks for sharing, Bridget!

I made these to bring to work and they didn’t even last past lunch time! These are so amazingly good. I have two more in the oven to take to people. Thanks for an amazing recipe.
Sounds like a success, Jenny!
So yum and great way to switch it up from banana bread. I didn’t have buttermilk so I used the milk and lemon trick. Worked out perfect! Thanks for sharing that trick.
