For a long time my top two recipes at HH were my savory oat flour bread and my honey oat flour bread.

Many of you found me by finding those recipes! Then came my banana oat flour muffins and banana oat flour bread. Those were a huge hit on Pinterest, google, and YouTube for a long, long time. Over the years, I've had a lot of fun making things out of oat flour, from baked goods to savory items, like oat flour pizza crust.

With the back-to-school season going strong, I thought re-sharing a bunch of oat flour recipes would be helpful since many people are looking for healthy snacks and lunch box additions or maybe make ahead healthy breakfast ideas. But, this round up is not limited to muffins, there are all kinds of things you can do with oat flour, just take a scroll and find out!

How to Make Oat Flour

Because I've made so much out of oat flour, I get a TON of questions about oat flour. Here is a quick little how-to-make oat flour section; scroll down for the recipes on what to do with it.

Like, a ton, a ton. I've actually been using oat flour for years and love using it in desserts, so I thought I'd do a little tutorial on how to make homemade oat flour and answer all the questions I've gotten over the years. So here we go! If you have some time, you can watch me make oat flour on YouTube below! (Have you subscribed to the HH channel yet? You can do that now by clicking here!)

What Is Oat Flour?

Oat flour is finely ground oats. It's considered a nutritious whole-grain flour.

Where Can You Purchase Oat Flour?

You can purchase oat flour that is already made on both Amazon and Thrive Market. They also have it at select grocery stores such as Whole Foods and Sprouts Farmers Market.

Can I Use Oat Flour Instead of All-purpose Flour?

Oat flour is very very absorbent, much more so than all-purpose flour. I would not recommend attempting to substitute oat flour for all-purpose flour.

Some sources say you can substitute up to 25% of all-purpose flour for oat flour, but I wouldn't recommend it. Personally, I hate food fails, but because I'm a recipe developer, I put up with them. Don't put yourself through that food fail if you don't need to!

Instead, I would look for a recipe that is formulated to use oat flour. Have a request for a recipe?!?! I'd love to hear it! Shoot me a DM on Instagram, email me at kelli(at)hungryhobby(dot)net, or leave a comment here!

Can You Use Steel-cut Oats To Make Oat Flour?

You can use any type of oats (steel-cut oats, rolled oats, instant oats) to make oat flour if you have the right equipment.

What Can You Substitute For Oat Flour?

Since oat flour is very absorbent, you need an equally absorbent flour to substitute for it. I typically find the best luck with chickpea flour (I get mine from Thrive Market.) You can also substitute 1.25 cups of oats.

Can You Eat Oat Flour Raw?

I get this question a lot! People often comment on overnight oats recipes, energy ball recipes, and my famous oat flour bread recipe about eating the oat flour "raw."

First, if you are using rolled oats, they are steamed in processing so they aren't actually raw. Chemical change "cooking" is happening with the oats or oat flour absorb liquid, so again, not raw. That being said, you can eat raw oats, it will not hurt you.

Are Oats Good For You?

Oats (and, therefore, oat flour) are rich in a specific type of fiber called beta-glucan, which can lower cholesterol and improve insulin sensitivity. Oats are rich in manganese, phosphorus, copper, B vitamins, iron, selenium, magnesium, and zinc.

This question was also answered in my post titled: Are Oats Inflammatory? The answer is yes, they are good for you unless you happen to be sensitive to components in them.

Are Oats Gluten-Free?

I get this question a TON!

Gluten is a protein found in wheat, rye, barley, and other grains, but not oats. In theory, yes, oats are naturally gluten-free. The problem occurs when oats are processed in a facility with other gluten-containing grains and become cross-contaminated.

If you need to avoid gluten, you'll need to avoid purchasing oats in the bulk bin in stores. You'll also need to purchase oats or oat flour (if you aren't making your own) that are certified gluten-free. My favorite is here.

Oats to Oat Flour Conversion

I find that the conversion is so very close to 1:1, but not quite there. UGH, I know. Why couldn't it be easy? For every 1 cup of oats, you'll get a tablespoon less of oat flour.

How to Store Homemade Oat Flour

Whole grain flour, like oat flour and whole wheat flour, spoil faster than processed flour, such as all-purpose flour. You can make big batches and keep oat flour in the fridge in an airtight container like a mason jar or ziplock bag for up to a month or in the freezer for six months.

PRO TIP: If you've kept your flour in the fridge or freezer, it will clump together, so it's best to sift it before using it in a recipe.

Step 1: Add oats to a blender or food processor.

Remember, you can use any type of oats to make oat flour, even steel-cut oats! I typically use rolled oats that I get in bulk from Costco. (Related: Healthy Shopping Costco List)

Step 2: Process for 1-2 minutes.

I usually set the timer for two full minutes and let it process the whole time when I use my food processor. When I use Vitamix or Ninja, I only do one minute!

Step 3: Optional: sift oat flour.

If you were unable to get a fine ground on your oat flour or feel like you still see chunks after two minutes, you may want to sift your oat flour. You can do this without a fancy sifter. Just use a mesh strainer over a piece of parchment paper.

Step 4: Store the oats in a labeled ziplock bag or airtight container.

Oat flour is so easy to make that I usually just make as much as I need for a recipe and store very little at a time.
