Oat Flour Banana Bread – Detoxinista
If you are hoping to bake with oat flour more often, you’re in good company here. I’ve spent years developing recipes with oat flour because it can be used in gluten-free baking without the need for extra gums or binders. (It does require eggs, but nothing special like xanthan gum.)
Even if you don’t keep oat flour in your pantry, you can make it in just a matter of minutes using a blender and regular rolled oats. It’s literally the easiest gluten-free flour to work with!
That’s why you’re going to love this oat flour banana bread recipe. I’ve tested it again and again, until I was confident it would turn out tasting like “normal” banana bread. You can’t taste the oat flour at all, and all of the guesswork is done for you!

Oat Flour Banana Bread Ingredients
Here’s what you’ll need:
- Oat Flour. If you’re not familiar with oat flour, it’s simply pulverized oats. You can even make oat flour at home if you have rolled oats on hand. While oats are naturally gluten-free, they can be contaminated during the manufacturing process, so shop for “certified gluten-free” oats if needed.
- Ripe Bananas. Wait to make this recipe until you have three very ripe bananas sitting on your counter. This recipe tastes best when using bananas that are almost overripe, making them as naturally sweet as possible.
- Eggs. Since oat flour is gluten-free, it doesn’t have the same binding protein (gluten) that wheat flour does. As a result, you’ll need to use more eggs to get a familiar banana bread texture. Don’t use an egg substitute! If you need an egg-free recipe, try my Vegan Banana Bread recipe, which has already been tested for you.
- Olive Oil. There’s a reason this recipe doesn’t call for butter or coconut oil. Those two options solidify when chilled, making the bread less tender as it cools. Use olive oil, or another mild vegetable oil, for the best texture.
- Coconut Sugar. If you prefer working with natural sweeteners, this is the best granulated sugar option, as it gives the bread an authentic taste and texture. Refer to the substitution notes below if you need to make a swap or want to reduce the sweetness.
- Baking Powder. In my experience, this works better for breads and muffins than baking soda. It provides lift, so your bread won’t be soggy in the middle.
- Spices. Ground cinnamon, vanilla extract, and salt complete the flavor, making each bite taste delicious.


How to Make Banana Bread with Oat Flour
Step 1:
Preheat the oven to 350°F and lightly grease a 9×5-inch loaf pan. Press a piece of parchment paper into the bottom of the pan to guarantee easy removal later.
Peel the bananas and add them to a large mixing bowl. Use a fork to mash the bananas until they are smooth and pureed. It’s okay if a few small lumps are still visible.
Add the eggs, olive oil, and vanilla extract to the bowl and mix until well combined.


Step 2:
Next, add the oat flour, coconut sugar, baking powder, ground cinnamon, and salt. Stir until the batter looks relatively uniform.
It’s okay if you still see a few small lumps of banana, but there should be no clumps of flour remaining.


Step 3:
Pour the batter into the prepared pan and smooth the top with a spatula. Sprinkle a few walnuts or chocolate chips on top, if you’d like extra texture. (This is optional.)
Bake until the center of the loaf feels firm to the touch, about 45 to 50 minutes. A crack should form in the center of the loaf, so it’s a good sign if you see it!
Remove the loaf from the oven and let it cool completely in the pan, or for at least 1 hour. It’s easiest to slice if the loaf is cool. Cut it into slices that are slightly less than 1 inch thick, yielding about 10 slices in total.


Storage Tips
You can store oat flour banana bread in an airtight container in the fridge for up to 5 days. It’s delicious when served chilled, or you can let it come to room temperature again.
Alternatively, you can freeze individual slices for up to 3 months. Thaw them in the fridge overnight before serving, or reheat quickly in the microwave using 30-second intervals.


- 3 large ripe bananas
- 3 large eggs
- ¼ cup olive oil
- 1 teaspoon vanilla extract
- 1 ¾ cups oat flour
- 1 cup coconut sugar
- 2 teaspoons baking powder
- 1 teaspoon ground cinnamon
- ½ teaspoon fine sea salt (I use Real Salt brand)
- chopped walnuts or chocolate chips (optional topping)

Pour the batter into the prepared pan, and smooth the top. Sprinkle chopped walnuts or chocolate chips on top, if desired. Bake at 350°F until the top rises and cracks in the middle, about 45-50 minutes. It should feel firm to the touch in the center.
-
Let the loaf cool completely before slicing, then serve. I think this bread tastes best when served at room temperature, but I store it in the fridge to extend the shelf life. It will keep well in an airtight container in the fridge for up to 5 days, and you can bring it to room temperature again 1 hour before serving.
Banana Note: In my experiments, three large bananas yielded approximately 1 1/4 cups of mashed bananas. It’s okay if you end up with a little more or a little less than that each time.
