What is oat flour?

Oat flour is a finely ground flour made, of course, from oats! It’s very light in texture and has a similar absorbency to coconut flour (another one of my fav gluten-free flours), making it much more absorbent than all purpose flour or wheat flour.

Is oat flour gluten free?

I always have oat flour on hand for all of my gluten-free baking adventures. If you buy oat flour made from certified gluten free oats or make your own with certified gluten-free oats, then you will have gluten-free oat flour. Be sure to double-check your packaging to be sure!

The best type of oats to use to make oat flour

I recommend using old fashioned rolled oats or quick-cooking oats (gluten-free if desired) to make your homemade oat flour so that it has a light and fluffy consistency. Steel cut oats may result in grittier oat flour. Learn about more types of oats, plus plenty of recipes in our guide here!

Benefits of using oat flour

  1. Tons of health benefits. Oats are a whole grain food, which means they pack vitamins, minerals, antioxidants, fiber and are even a great source of protein.
  2. It will fill you up. Because oats are fiber & protein packed, they’ll keep you feeling satisfied for longer. That means with recipes using oat flour (as opposed to regular flour AKA white, refined flour) you’re less likely to spike your blood sugar and experience that 3pm hanger later.
  3. Versatility. Oat flour is extremely versatile, and if you’re like me, you always have old-fashioned oats in your pantry! You’ll see that I use oat flour in tons of baking recipes and even savory ones because it provides the perfect texture and holds recipes together. It also makes a great substitution for other flours in baking — just be sure to read the recipe’s notes section to see if it’s a good sub.

Can I use oat flour in place of all purpose flour?

Unfortunately, no, I would not recommend using oat flour 1:1 in place of all purpose flour. The texture and liquid ratios will be very different when making this swap. However, you can substitute half of the all purpose flour in your recipe with oat flour! For example, if the recipe calls for 1 cup all purpose flour, feel free to use 1/2 oat flour and 1/2 all purpose flour.

Overall, I recommend only using oat flour in recipes that specifically call for it within the recipe or in the notes section.

Tips on measuring oat flour

  • After blending your oats and before adding oat flour to a recipe, be sure to measure it out to what the recipe calls for.
  • 1 cup of rolled oats equals about 3/4 cup oat flour, so you’ll need a bit more rolled oats if you need a full cup of oat flour in your recipe.

Storing tips

Store your homemade oat flour in an airtight container at room temperature. It has a shelf life of about 3 months.
