What is Oat Flour?

Oat flour is made from ground oats. Simple and sweet right?

But don’t be fooled, this flour is capable of making some incredible baked goods and breakfasts. We’re talking light and fluffy breads, pancakes, waffles, golden brown cookies, all the essential things.

Is Oat Flour Gluten Free?

The short answer is YES! Both pure rolled oats and flour made form them are gluten free. However, if the oats are processed in facilities with wheat and other grains, there’s a good chance they’ll contain traces of gluten.  If you are looking for certified gluten free oat flour, all you need to do is make sure the oats you purchase say “certified gluten free” and then you can make your own flour at a fraction of the cost.

No need to worry, there are multiple sources of gluten-free oats and flours this one is my favorite. Or you can take matters into your own hands, like we’re doing today, and make homemade oat flour!

How to Make Oatmeal Flour

Making oat flour is wonderfully simple, and I have a hard time figuring out why people haven’t caught on sooner. Homemade Oat Flour has all the benefits and quality of store-bought, and it’s way less expensive. All you need is a blender/food processor and old-fashioned oats.

  1. Add 1 to 2 cups old-fashioned oats to a blender or food processor.
  2. Place the lid on, and give it a go on high speed until the oats turn into a fine powder.
  3. Transfer to an air-tight container and store for in the pantry for about 3 months.

To make oats flour, I always use my Blendtec. Now, you probably already know I love using my Blendtec for my favorite smoothie recipes but it’s the by far the best tool for making your own flours as well!
