How to Make Oat Flour & 10 Recipes

There is no need to spend a lot of money on oat flour when you likely already have everything needed in your own pantry to make it in less than 2-minutes. It really is so simple and useful!

One great thing about making your own oat flour is that you can prepare as much or little as needed without having to store extra bags of specialty flour that get used infrequently. Making this gluten-free flour is super simple and inexpensive.

What is oat flour?

Oat flour is a whole grain gluten-free flour that is made from oats. It can be made using old fashion oats, quick-cooking oats, and even steel-cut oats though steel-cut takes just a little longer to blend since they are a thicker cut.

Making your own oat flour is a very cost-effective option compared to other specialty flours such as almond, coconut, and quinoa flours. In addition to being naturally gluten-free, oat flour is loaded with plenty of fiber and protein.

Substituting with other flours

I often am asked by followers how to substitute other flours with oat flour when baking and cooking. Most of the time, people are asking because they are avoiding gluten and want to replace wheat flour or traditional white flour with a gluten-free option.

The good news is that oat flour is very user-friendly and can usually be substituted for white and wheat flour at the same ratio. So, if a recipe calls for 1 cup of whole wheat flour, using 1 cup of oat flour instead should work just fine in most cases.

Cooking with oatmeal flour

Not that many years ago, the only flours that were used regularly in recipes were the standard all-purpose white flour and whole wheat. Things have really changed since then, and people are incorporating a wide range of other flours like spelt, rice, almond, oat, and many more in their favorite recipes.

Some people are in search of gluten-free flour, and others are just interested in trying something new and different. The problem is that most of these bags of specialty flours can be quite pricey, especially if they are only going to be used for one or two recipes.

Luckily, with oat flour, I’m betting you already have everything needed in your cupboard to make the exact amount for that recipe without wasting a penny!

Is oat flour gluten-free?

Oats are naturally gluten-free, however, they can be cross-contaminated during processing if the facility also processes other grains. If you are gluten-intolerant, be sure any oats bought say “certified gluten-free.” It is so easy to make gluten-free oat flour at a fraction of the cost of those name brands.

How to make oat flour

Making your own homemade oat flour is super easy. Simply add old fashion or quick-cooking oats to your blender, food processor, or even coffee grinder.

Next, blend or pulse oats until they are ground into powdery flour, approximately 1 minute or less. Time will depend on the power of your appliance.

If needed, stop and stir oats then pulse again to make sure they are completely blended.

One cup of oats makes just under 1 cup of flour. There is about a tablespoon difference, with the finished flour product being the lesser measurement.

I make my oat flour in my Vitamix, and it creates a super soft and fluffy finished product to be used in oat flour recipes.

Use immediately in your favorite recipe or store in an airtight container. I vote for using it immediately in a delicious treat like these Heavenly Tootsie Rolls from the Physicians Committee for Responsible Medicine.

Storage and freezing

If you want to make a large batch of oat flour to keep on hand for recipes, simply store it in an airtight container at room temperature like you would other flour varieties. It should keep for at least 6 months or longer.

It can also be stored in your refrigerator or freezer if it won’t be used for long periods of time.
