Since my husband eats gluten-free and I tend to feel better when I limit my processed gluten intake, I love finding easy ways to make gluten-free baked goods. Oat flour has quickly become my favorite wheat flour alternative!

While oat flour is not quite a perfect 1:1 ratio substitute for wheat flour, I have made so many tasty recipes with it from banana muffins to chocolate almond biscotti. It has quickly become the primary flour I use in my kitchen!

What Does Oat Flour Taste Like?

Food made with oat flour tends to taste very similar to recipes that call for 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 recipes.

Is it Actually Healthy?

Oats are full of a variety of amazing nutrients which make them one of my favorite grains to bake with!

  • High in protein
  • Contain antioxidants 
  • Good source of fiber
  • Contains important minerals

For the most nutrition possible, try to buy organic sprouted oats to make oat flour.

Is Oat Flour Gluten-Free?

Oats are naturally gluten-free! However, like all foods, unless they are certified gluten-free, there is a risk that they were contaminated with gluten from being processed in the same facility as gluten or even grown near wheat fields.

If you are extremely sensitive to gluten, you should always make sure to purchase certified gluten-free oats.

Others, like my husband, try to avoid gluten in general but won’t suffer any major effects if they eat a small amount. Because of this, I don’t personally worry about buying certified gluten-free oats.

How to Use Oat Flour

Oat flour can often be used like wheat flour, and there are many recipes that call for 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, I recommend finding recipes that specifically use oat flour. There are so many delicious options from muffins to pancakes to cookies and other desserts!

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 it for 18 months.

The Only Tool You Need!

Oat flour is extremely quick and easy to make, and the only tool you need is a food processor or high speed blender.

Begin grinding the oats and continue until they turn into a fine powder.

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 your food processor or blender every so often.

You can use your oat flour right away or store in an airtight container for later.
