What is Oat Flour?
Oat flour is a whole-grain flour made from rolled oats. It is rich in nutrients such as manganese, molybdenum, phosphorous, copper, biotin, vitamin B1, magnesium, chromium, and fiber.
How to Make Oat Flour
Making oat flour is very simple! It requires just 1 ingredient, 1 blender, and 5 minutes.
Simply add rolled oats to a blender and blitz for about 15 seconds until you have a fine, powdery flour.
How to Use Oat Flour in Recipes
Now that you’ve seen how simple it is to make oat flour, it’s time to put it to use!
Oat flour works well in recipes that require a dense texture and mild, slightly sweet flavor. We typically like to use a mix of flours in a recipe in order to achieve the ideal texture and flavor.
Here are some of our favorite recipes using oat flour as an ingredient:
- Life-Changing Banana Walnut Pancakes (GF)
- Chocolate Chocolate Chip Pancakes (GF)
- Peanut Butter Flaxseed Pancakes
- Gluten-Free Vegan Breakfast Cookies
- Fudgy Gluten-Free Chocolate Cake
- 1-Bowl Chocolate Zucchini Bread
- Vegan Cherry Dark Chocolate Chip Muffins

How to Make Oat Flour
Instructions
- Add oats to a high-speed blender and blend on high until a fine, powdery flour is achieved — about 15 seconds (it’s fast!). Be careful not to overblend or the oat flour will get clumpy.
- Check your blender for bits of oats and continue blending, occasionally removing your blender from the base and shaking to ensure all oats are well blended.
- Transfer to a jar or container and store up to 1 month unrefrigerated, often longer. See above for recipe suggestions.
Michelle says
Does this flour need to cool off before storing? It is really warm out of the blender and I am afraid for it to get moisture inside the jar.
Hi Michelle, though we haven’t had issues with it, it wouldn’t hurt to let it cool first especially if storing at room temperature. You can spread it out on a baking sheet to help it cool faster. Hope that helps!
Holly says
I wouldn’t bother blending the oats if you’re using them for a bath. I use oats straight out of the bag and a little coconut oil and can confirm it does wonders for my eczema! Hope this helps x
Gem says
I like the container you use for storing the flour. Where can I get them? the labels also?
Thanks,
Gem
Hi Gem, the container is a Kerr pint-size jar and the label is made with a Dymo embossing label maker. Hope this helps!
Kay Reyes says
Does 1 cup of oatmeal equal 1 cup of flour after it’s blended?
Yes!
Geri says
When you make oat flour for baking, do you use the same amount of oat flour as oatmeal in the recipe? For banana bread, oatmeal cookies, etc?
Hi Geri, we use the oat flour in recipes that call for oat flour and still use oats when needed! Hope this helps!
Jude says
Can I use steel oats?
Hi Jude, we’ve never made oat flour from steel cut oats so we cannot guarantee results, but according to google it is possible. Let us know how it goes if you give it a try!
Barbara Laporte says
Thank you very helpful
Glad to hear it! Thank you for sharing, Barbara!
Tom From Texas says
Can the oat flour be made in a Food Processor instead of a blender?
Hi Tom! It is possible to make oat flour in the food processor but it will take longer and may not get quite as smooth.
Anon says
If you have a spice/coffee grinder, that’s a better substitute for an expensive blender and I find my flour is more uniform than the food processor
Katie says
Thanks for this “how-to” guide! I use regular rolled oats to make mine. Before grinding, I like to toast the rolled oats on top of the stove in a dry cast iron skillet. Gives them a slightly nutty flavor. I toast, cool, and grind the oats in my noisy “old faithful” blender, then store the oat flour in a tightly sealed mason jar. Put in the freezer if you can’t use it all in a month or so.
The oat flour is very good to make puddings, pancakes and baked goods. I add ground chia seeds to oat flour for protein and to thicken the batter (similar to adding eggs).
I also use toasted oat flour to make oat milk. I shake about 1 Cup of oat flour in a quart jar for just a few seconds with 3 Cups of VERY COLD water and (optionally) a little date sugar and vanilla to taste. I put it in the refrig overnight to develop the flavor and allow the oat solids to settle, then strain the ‘milk’ and use the solids in porridge, soup, facial etc.
Lovely! Thanks for sharing, Katie! xo
Sheila Ben David says
Can you use quick cooking oats instead of rolled oats?
Hi Sheila, we haven’t tried that, but we’d assume so!
Maia says
Hi! For tjengluten free flatbread, what is a good substitute for the oat flour? Thanks!
Hi Maia, the next best sub would be a GF flour blend but we haven’t tried it, so let us know if you do!
Lucy forcier says
Is this what they talk about when they say to put oatmeal powder in a bath for dry skin? Do you know anything about this like how much to use
Hm, good question! Probably!
Tracy says
If a recipe uses 2.5 cups of rolled oats, how much oat flour will that make? I already have oat flour I need to use, so I don’t want to grind the oats to get flour.
Hi Tracy, it will make around the same amount!
Tracy says
Can you use unhulled oats to make oat flour?
We haven’t tried that, but we don’t think it would work.
Somya says
First of all, thanks for showing this.
Second, do we need to store it for up to 1 month before using this?
Hi Somya, we think you’re referring to how long it lasts? That will depend on the temperature and humidity in your kitchen. You can store in the fridge or freezer for longer term storage. Hope that helps!
Kiran khadka says
How can I use oats flour in preparation of fibre rich paneer ??
Hi Kiran, we aren’t sure, sorry. Let us know if you figure it out!
Karen says
Can I Substitute oat flour for one of these flours: almond, coconut, hazelnut or cassava flour?
Thanking you in advance!
Hi Karen, it depends on the recipe. Did you mean to comment on a specific recipe?
Kathryn Newburn says
Ask Arthurs flour folks. Regarding oats, it is the bran that has the fibre Kiran
Christina says
Could you use Steel Cut Oats to make this flour? Thanks in advance!
Hmm, that’s a good question. We’ve never tried that, but it might work? Let us know if you try it out!
Chriselda says
Hi! Would 1-minute quick oats be okay to use for this? I have a whole container of Quaker gluten-free oats of this kind and want to avoid having to buy more (and having to go back to the store for the 6th time…).
I hope your day is a beautiful one ✌️♥️?
PS. I’m making your pumpkin soup again… it’s one of my favorite things to make and have for food prep. Which reminds me, I’m wondering if I were to roast the pumpkin and put it in the fridge until the next day or the day after that, it it would still be good to use (I tend to cook at night, my blender is very loud, noise echoes in my apartment, and I have next-door and upstairs neighbors…).
Thank you for your help! :)
So kind! As for the oat flour, I think that should work!
Charu Gohel says
Hello
Does Oat flour have binding capacity like wheat flour?
Hi Charu, unfortunately, it doesn’t. We like to use a combination of gluten-free flours to best simulate the texture of wheat-containing products.
Stephan says
Hello
You mentioned to mix gluten-free flours for a better texture. Can you recommend some tested options to mix with oat flour?
Thank you :)
Hi Stephan, we like using a mix of almond flour, oat flour, and our DIY GF blend!
Sam says
Hi 🙂 do you have a blender recommendation for oats? I’d like to my my own oat flour and oat milk, but want to make sure I’m buying a blender that will work well. Thank you
Hi Sam, yes! You can find our blender review here. Hope that helps!
