What is Oat Flour?

Oat flour is a simple and inexpensive flour made from you guessed it – oats! It’s a great option for gluten free baking and can be used in several different recipes.

While you can buy oat flour at some grocery stores or online, you can easily make it yourself at home for pennies on the dollar.

Why Oat Flour Is Great for Gluten Free Baking?

If you have any experience with gluten-free baking you know that it can be a little tricky. I’ve had my fair share of baking fails when experimenting with alternative flours.

I love using gluten-free flour blends for more complex recipes when I need a one-to-one substitution for all-purpose flour. But, there are some great recipes that are specifically designed to be made with oat flour and I always love the way they turn out.

In addition to being easy to work with oat flour is also much less expensive than gluten-free flour blends and can be made at home!

Which Oats are Best?

To make oat flour you’ll need old fashioned “rolled” oats. I do not recommend using steel cut or quick oats for oat flour.

While oats are naturally gluten free, they can sometimes be cross-contaminated with gluten if they are processed in a facility that makes other items that contain gluten. If you need the oat flour to be certified gluten free then be sure to grab certified gluten free oats.

How to Make

Step One: Measure and add the oats to a high-powered blender or food processor.

Step Two: Pulse or blend the oats until they turn into a fine powder. If you are using a blender, you may need to give it a shake to ensure that all of the oats blend evenly. 

Step Three: Transfer the oats to an air-tight container and store in a cool dark place. 

Frequently Asked Questions

Can I substitute oat flour for all purpose flour?

While it might work sometimes, depending on the recipe, I would not recommend using oat flour as an automatic substitute for all purpose flour in every baking recipe. Baking can be tricky and the amount of liquid, eggs, butter, etc. may need to be adjusted if you change the type of flour being used. 

How much oat flour will one cup of oats make?

One cup of oats will typically yield around three-fourths a cup of oat flour. 

What’s the best way to store oat flour?

Store your oat flour in an air-tight container to avoid any moisture creeping into flour and causing it to clump. You can store in a cool dark place like your pantry to keep it fresh. 

How do I use oat flour?

My preferred way to use oat flour is muffins! I have several different muffin recipes made with oat flour on All the Healthy Things that I have linked to, below. You can also use oat flour as a substitute for the almond flour in my fruit crisp recipes, as the base of pancakes, and more!
