What Is Oat Flour?
Oat flour is basically ground oats, flour made from old-fashioned oats or quick-cooking oats. Most oat flour recipes use one or the other type of oats. A few people use steel-cut oats that make an oat flour too high in fiber and, therefore very liquid absorbent.
How To Make Oat Flour At Home
It’s very easy to make oat flour at home. All you need is a blender or food processor. Next, choose between rolled oats – also called old-fashioned oats – or quick-cooking oats. Finally, add at least 3 cups of this ingredient to the high-speed blender and blend for about 45 seconds or until it turns into flour.
That’s it! You just made oat flour with one simple ingredient.
How To Make Oat Flour From Steel-cut Oats
To make oat flour from steel-cut oats, you must use a high-speed blender. In fact, steel-cut oats have a strong outer layer, and they won’t turn into oat flour in a food processor. Steel-cut also oats contain way more fiber than rolled oats.
So if you are making oat flour from steel-cut oats, it will be way more liquid absorbent than oat flour made from rolled oats. It means that in a recipe that calls for oat flour, you may have to use only 1/2 cup of oat flour made from steel-cut oats to reach the same texture.
How To Store Oat Flour
You can store homemade oat flour in a sealed glass mason jar, in the pantry, or in the fridge for up to 6 months. You can also freeze oat flour in zipped bags and thaw it the day before using it.

Your friend, Carine
are oats measured before or after grinding into flour?
Since this recipe makes oat flour, you measure the oats before turning them into flour. However, you can make as much or as little as you want! It depends on what you want to do with the oat flour after.
Does store bought oat flour, such as Bob’s or Arrowood not work in baking recipes ? I already have a bag of each.
