Banana bread is probably my number one snack food. I make it all the time, and I have a few different versions. When I don’t want to turn on my oven, I even use my Instant Pot to make banana bread.

This oat flour banana bread is my new favorite version. You can’t really tell that it uses oat flour, and it’s more nutritious than typical banana bread because of the oats. My family loves to have this soft, hearty bread on hand for snack time.

At $.28 per serving, this is a very frugal recipe. It’s so easy to make, too.

How to Make Oat Flour

I use a high-powered blender to make oat flour out of traditional rolled oats. Process the oats at a high speed until you have a fine flour. This takes about 30 seconds of processing. A Vitamix or Blendtec blender will work well for this.

A food processor doesn’t work as well at making a fine powder of the oats. If you don’t have a high-powered blender, you can buy packaged oat flour.

For gluten-free oat flour, be sure to use oats that are labeled gluten-free. There can be trace amounts of gluten in regular oats.

Oat Flour Banana Bread Tips and Frequently Asked Questions

Can you mash bananas in the blender?

Bananas can be mashed by hand with a fork, or you can mash the bananas in a blender. If you choose this shortcut, you can go ahead and mix all the wet ingredients in the blender along with the banana, then transfer everything to a large bowl and stir the wet and dry ingredients together.

How ripe should bananas be for banana bread?

The bananas should be very ripe with brown spots for the best oat flour banana bread. They really can’t be too ripe (unless they’re moldy). If the bananas aren’t especially ripe, you may want to increase the maple syrup a bit. I don’t recommend making this recipe with bananas that still have green on them, because the flavor won’t be as good. Wait a few days until they’re ripe. For this recipe, weigh your bananas and use 1 pound (about 3 bananas).

What can I add to banana bread?

This recipe is delicious as written, but you could also add chocolate chips, chopped walnuts, or blueberries for a unique variation. And if you don’t have quite enough banana, you can add applesauce or pumpkin puree in place of some of the mashed banana.

How long does banana bread last?

This oat flour banana bread can be stored at room temperature in an airtight container for up to three days. The leftovers can be frozen for several months.

Prep Time:10 mins
Cook Time:50 mins
Total Time:1 hr

Ingredients

  • 2 1/4 cups rolled oats
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 3 very ripe bananas 1 lb unpeeled
  • 2 eggs
  • 1/3 cup coconut milk or other milk of choice
  • 1/3 cup melted coconut oil
  • 1/3 cup pure maple syrup

Instructions

  • Preheat the oven to 350 degrees and grease a medium (8 1/2 by 4 1/2 inch) loaf pan.
  • Blend the oats in a high powered blender for about 30 seconds, or until they form a fine flour. (Alternately, you can use 2 1/4 cups oat flour). Add the baking powder, baking soda, and salt and process briefly. Transfer the dry ingredients to a bowl.
  • Using the same blender, add the bananas, eggs, coconut milk, melted coconut oil, and pure maple syrup. Blend for about 10 seconds to combine the liquid ingredients. (Alternately, you can mash the bananas by hand, then stir together the wet ingredients in a large bowl.)
  • Transfer the wet ingredients to a large bowl, and stir in the dry ingredients. The batter will be quite thin.
  • Transfer the batter to the prepared loaf pan. Bake for 50 minutes, or until the bread is nicely browned and a toothpick inserted in the center of the loaf comes out clean.
  • Cool on a wire rack for 10 minutes in the pan, then remove the bread from the pan. Cool completely on the rack.
  • Store in an airtight container for up to 3 days, or freeze for later.

  1. I have begun using oat flour recipes a lot — and– I add the pulp from juicing apples and carrots. Muffins, waffles, banana bread. I feel like I’m getting some benefit w/the fiber I would normally throw out.
    And, it’s a big PLUS using oat flour rather than a g-f white flour (Bob’s Red Mill 1-1 is what I had been using). The cost is minimal compared to other flours. And, since I love oats….yummy.

  2. Hi there! This is my favorite recipe recently and id like to make this break with other seasonal fruits. Can I swap out the banana puree for any other fruit like blueberry purée, or pumpkin puree?

    1. I think it would work well with pumpkin puree or apple puree, but I’d add a little extra sweetener to make up for the lack of banana. Please let me know if you try it.

  3. 5 stars
    Delicious! Every bite was so yummy! Thank you so much for an OAT FLOUR ONLY recipe.
    Could you replace the bananas with canned pumpkin? If so, how much pumpkin would you use? What about an applesauce bread, could you just substitute applesauce for the banana?

    Please create some more OAT FLOUR ONLY baked recipes/breads/muffins/cookies.
    Thank you!
