Personally, I think this is the best banana bread. This recipe relays solely on oat flour. No whole wheat flour, gluten-free flour, or all-purpose flour is used.
The oats add a nutty flavor and you can customize the add-ins just like with a standard banana bread recipe.
It does not contain any milk or butter, so it is dairy free. There is no need to buy any special oat flour. You can make oat flour from whole oats in under a minute! Save leftover flour to make oatmeal waffles!

📖Why My Recipe Works
- This blender bread recipe is naturally gluten and dairy free. But you won't even notice what's missing because this banana bread is moist and has a fluffy texture thanks to a little bit of oil and brown sugar.
- This is a blender recipe, no bowls, mixers, or whisks are needed.
🧾Ingredient Notes
- Bananas- If you are new to baking with bananas the most important thing you need to remember is that you must use overripe bananas. If they are a bit too mushy to eat on their own they are perfect for this banana bread.
- Oat Flour- You can buy oat flour but it is oddly expensive and not all grocery stores carry it. I make my own oat flour at home. To keep this banana bread recipe gluten-free be sure to buy certified gluten-free to prevent cross-contamination.
- Brown Sugar- You can use light or dark brown sugar. I recommend dark brown sugar when using white sugar and light brown sugar when using coconut sugar.
- Granulated Sugar- You can cane (i.e. white) sugar or coconut sugar.
- Eggs- For baking, you want to be sure to buy large or extra large eggs. What an extra creamy bread? Try using duck eggs. The larger yolks add more fat to the loaf. I do not recommend substituting flax egg in this recipe, it made the final bread gummy when I tested it.
- Vanilla Extract- Or an equal amount of vanilla paste.
- Oil- Use your favorite neutral oil. This can be vegetable oil, coconut oil or olive oil.
- Leveners- This recipe relies on both baking powder and baking soda to help the heavier oat flour rise.
⏲️How to Make Oat Flour Banana Bread
Make the Oat Flour
Make your oat flour in a food processor or high speed blender. Measure the final flour the not the rolled oats.
Prep
Because this cake is so moist I recommend lining the bottom of a 5-inch loaf pan with parchment paper. Fully grease your pan with coconut or vegetable oil to prevent sticking.
Make the Batter
Blend the bananas, sugar, and eggs until frothy. Then add the oil and the flour.
Bake
I find that oat flour banana bread takes longer to bake than a loaf of traditional banana bread.
Place the pan on a wire cooling rack, and let it cool for 10 to 15 minutes before turning out of the loaf of bread.
💭 Banana Bread Variations
This is a delicious recipe on its own. But it is also incredibly easy to jazz up! I always recommend following the recipe the first time you make it and getting creative the second time.
- Chocolate Chip Banana Bread- Add 1 cup of chocolate chips at the end. You will need to stir in by hand. Or do ½ cup chocolate chips and a ½ cup chopped walnuts for chocolate chip nut bread.
- Coconut Banana Bread- Reduce the oat flour by ½ cup. Add ½ cup of coconut flour and ¼ cup shredded coconut.
- Bourbon Banana Nut Bread- Add 3 tablespoons of bourbon to the pureed banana. And stir in ¾ cup chopped walnuts right before baking.
- Oat Flour Banana Muffins- Basic muffin recipes and quick bread recipes are interchangeable. Follow the recipe as written and pour the batter into a lined muffin tin. Bake at 350 F degrees for 25 minutes.
👩🏻🍳 Expert Tips
- If you make oat flour, just dump it into a bowl and add the bananas without washing the blender. The small amount of residual flour won't affect the recipe and it will save you a few minutes.
- Decorate the top before baking with strips of bananas, chopped nuts (like pecans or walnuts), or a handful of whole oats.
- Need to quickly ripen your bananas? Place the bananas, still in their peels, on a cookie sheet and bake at 300ºF for 30 minutes. The banana peels will be completely black but perfectly sweet on the inside. Allow them to cool before using.
- With the processor running, slowly add the oil. If using coconut oil be sure to melt it first. Not too hot, you don't want to cook the eggs. Process an additional 30 seconds until emulsified.
- Let it cool completely, don't be surprised if the bread drops in height a little. This is normal for oat flour quick bread recipes.
🌡️Storing Leftovers
Make Ahead: Once it's fully cooled, wrap it in plastic wrap and keep it on the counter for up to three days.
Storing:For a longer stretch, refrigerate the wrapped loaf for up to five days. Bring it back to room temperature before slicing-cold banana bread can taste a little dense.
Freezing: To freeze, wrap the whole loaf or individual slices in two layers of plastic wrap, then place them in a freezer-safe bag or container. Label and freeze for up to 3 months. When ready to enjoy, remove the bread from the bag (but leave it wrapped) and thaw at room temperature for a few hours.

Wowie! I used Swerve sugar replacement for both the white and brown sugar and (accidentally) used 1/4 cup white Swerve instead of 1/2 cup. I ended up using two entire cups of mashed bananas, and this was so delish. I cooked for 50 minutes total, and then enjoyed this as a dessert. My boyfriend has no idea it was healthy. 10/10 will make again!! I love that this recipe uses oat flour and coconut oil. Super moist.
