I have been making this awesome oat flour banana bread recipe three weekends in a row. It is easy, requires one bowl, has perfect amount of sweetness and tastes absolutely delicious! My kids say they would never be able to tell this banana bread is made with oat flour.

And I do love oat flour because it makes baked goods light, offers extra nutrients and is gluten-free. I find with this banana bread there is no heavy feel afterwards like with whole wheat flour banana bread. You be the judge!

Ingredients and Substitutions

To make oat flour banana bread you will need just a few simple ingredients. Oat flour is affordable flour you can find in any grocery store. Other ingredients are the usual any banana bread recipe suspects.

  • Bananas: Use ripe bananas that have some brown spots or overripe bananas will work well too. The more ripe are your bananas, the sweeter is the quick bread. Do not use green bananas, here is how to ripe bananas faster. You will need about 4 medium to large bananas equal to 1 1/2 cups of mashed bananas.
  • Egg: One large egg for binding. You might be able to use flax egg or chia egg but I have not tried.
  • Oil: Mild tasting oil like avocado oil, even any olive oil or melted coconut oil will work.
  • Greek yogurt: Plain. You might be able to use more thin regular yogurt.
  • Gluten-free oat flour: Store-bought oat flour or homemade oat flour. I highly recommend to weigh it on the kitchen scale to make sure you use correct amount, if possible.
  • Maple syrup: Any liquid sweetener will work. Honey, agave nectar etc.
  • Baking staples: Pure vanilla extract, cinnamon, baking powder, baking soda, salt.
  • Chocolate chips: I use dark chocolate chips but they are completely optional.
  • Walnuts: Make sure to chop them coarsely. Pecans or hazelnuts would be great too or omit.

Tips for Best Results

Here are the best tips to help you nail this healthy oat flour banana bread recipe.

  • Use ripe bananas: The riper, the better. Black bananas are the best but as photos show very yellow bananas will work too. You can also use ripe frozen bananas that have been thawed.
  • Weigh the oat flour: Use scoop and level method when measuring oat flour. I like to weigh my oat flour on kitchen scale just to be sure because it’s a bit different than regular flour.
  • Chop up the nuts: Baked goods with oat flour are more fluffy than regular ones, so make sure to chop nuts into small pieces so your banana bread isn’t falling apart when you are slicing it.
  • Let bread cool: Give it about 1-2 hours to cool off on a wire rack. Your banana bread will be much easier to slice.

Variations and Add-Ins

Oat flour banana bread is extremely versatile! Here are few more ideas to switch things up:

  • Add up to 1/3 cup raisins or dried cranberries
  • Substitute white chocolate chips, mini chocolate chips or coarsely chopped chocolate
  • Use 1 tablespoon of pumpkin pie spice instead of cinnamon
  • Swirl 1/2 cup of softened cream cheese or peanut butter on top of the loaf
  • Top with sea salt flakes

Storing and Freezing Banana Bread with Oat Flour

Store: To keep oat flour banana bread fresh for up to 5 days, store it in an airtight container for a few days and then refrigerate for another 3 days. I have to be honest and say it never lasts more than 2 days in our house.

Freeze: It is best to freeze baked and cooled banana bread unsliced. It retains moisture better that way. Freeze in an airtight container for up to 3 months. Thaw on a counter for a few hours.

You can also freeze individual slices wrapped in double plastic wrap. This gluten-free banana bread recipe makes for delicious breakfast, healthy snack or guilt-free dessert.
