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. Prepare as much or little as needed without having to store extra bags of specialty flour that get used infrequently. Making gluten-free oat flour is simple and inexpensive.

What is oat flour

Oat flour is a whole grain gluten-free flour that is made from oats. It’s 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.

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 flours, 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.

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 1 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.

Though you do not need a high-powered blender to make oat flour, this is the one that I personally use and highly recommend. Of all the appliances in my kitchen, this Vitamix is the one I could not do without. I’ve never met a recipe or kitchen-task it can’t handle.

Nutrition in Oats

Oats are a whole-grain food and are rich in fiber, manganese, the B vitamins thiamin and riboflavin, vitamin E and protein. They’re also low in sodium and fat and free of sugar, cholesterol and saturated fats.

One cup of rolled oats contains 160 calories, 3 grams fat, 10 milligrams sodium, 28 grams carbohydrates, 4 grams fiber and 6 grams protein; it also provides 4 percent of the daily value for calcium and 12 percent of the daily value for iron.–LiveStrong
