Ingredients

  • Rolled oats – Quick oats will also work. If you’re gluten free, make sure your oats are certified gluten free. I also prefer to use sprouted oats for added nutrition.

Tools Needed

Step-By-Step Instructions

Rolled oats in a food processor ready to be ground.

Step 1: First, fill your food processor (or blender) 1/4 to 1/2 full of oats.

Step 2: Then grind the oats until they turn into a fine flour-like powder. The time this takes can vary significantly based on your food processor’s power and the amount of oats you’re grinding.

Chef’s tip: While oat flour won’t ever be quite as fine as wheat flour, the longer you let your food processor or blender run, the finer it will become. If necessary, scrape down the sides of the bowl every so often.

Tips for Success

Don’t overfill your food processor – This can make it cause the oats to stay in larger pieces and not turn into a fine flour as easily.

Grind until the texture is smooth – The fineness of the flour has a significant impact on the texture of baked goods, so make sure to grind until smooth.

How to Store

Oat flour made from fresh oats will keep for a few months in an airtight container in a cool, dry, dark place. If you would like to store it even longer, you can refrigerate it for up to a year or freeze for 18 months.

How to Bake with Oat Flour

Oat flour can often be used like wheat flour, and there are many recipes that use it. While you can experiment with substituting it for wheat flour with a 1:1 ratio, since it is naturally gluten-free and more absorbent than wheat flour, most recipes will need some modifications.

For best results, use it in recipes that specifically call for oat flour. For baking ideas, check out all my oat flour recipes!

FAQs

What does oat flour taste like?

Food made with oat flour often tastes very similar to recipes that use wheat flour. However, it does add a slightly sweet, nutty flavor which makes food taste richer.
Since it has a neutral flavor, it’s extremely versatile and can be used in a variety of sweet and savory recipes.

Is oat flour gluten-free?

Yes, oats are naturally gluten-free! However, unless they are certified gluten-free, there is a risk of them being contaminated from being processed in the same facility as gluten or even grown near wheat fields. If you are celiac or extremely sensitive to gluten, make sure to purchase certified gluten-free oats for oat flour.

Is oat flour healthy?

Yes, oat flour is considered healthy. It is full of a variety of nutrients including protein, antioxidants, fiber, and various minerals. For the most nutrition possible, use organic, glyphosate-free, sprouted oats to make oat flour.
