Olive Oil Banana Bread Bars


Last Updated on January 19, 2023

Chocolate chip olive oil banana bread bars are gluten-free, dairy-free, and the perfect little sweet snack to make for the week.

Olive Banana Bread Bars

These olive oil banana bread bars are light and fluffy, with the perfect amount of chocolate chips in every bite. They’re made with just 10 simple ingredients and come together so easily.

These bars are the perfect way to use up ripe bananas, and an easy snack to have around to pair with your cup of tea or coffee.

I used a combination of my favorite gluten-free baking flours, almond and oat flour, to get a soft, cake-like texture. They’re lightly sweetened with coconut sugar, and made with olive oil for the perfect flavor balance.

What you’ll need to make olive oil banana bread bars

  • Spotty bananas– the more spots, the better! Brown bananas are the ideal bananas to bake with because they’re a lot sweeter. 
  • Eggs
  • Coconut sugar or brown sugar
  • Olive oil
  • Vanilla extract 
  • Oat flouryou can make your own by blending whole oats until fine, but I prefer store-bought since its a lot finer
  • Almond flour– super fine almond flour is my go-to when baking. It has a lighter texture and isn’t as grainy as course almond flour or meal
  • Baking soda
  • Salt
  • Semi-sweet chocolate chips

How to store your chocolate banana bread

These banana bars are freezer friendly, so they can be prepared and stored in the freezer, fridge or on the counter.

  1. On the counter– if you plan on eating your banana bars rather quickly, it’ll stay fresh in an airtight container on the counter for 3 days.
  2. Fridge– If you wanted to enjoy it throughout the week, you can store it in the fridge for up to 1 week. Warm it in the microwave for a melt-in-your-mouth treat!
  3. Freezer– slice your banana bars and freeze them in an airtight container or bag for up to 3 months.

  1. Delicious! One of the best GF banana recipes!! Really moist and doesn’t taste GF.

  2. Could this be made with another flour besides almond? We have a nut allergy.

    • Hey Jill, I personally haven’t tested this recipe with any other flour so I can’t say for sure
