WHAT YOU NEED TO MAKE YOUR OWN OAT FLOUR:

1. ROLLED OR QUICK-COOKING OATS. You can make oat flour easily with rolled oats (sometimes labeled old-fashioned oats), or quick-cooking oats. I don’t recommend steel-cut oats for making oat flour, as they can strain your blender motor.

2. A BLENDER OR FOOD PROCESSOR. To make oat flour, you’ll put those oats in a blender or food processor and blend until the oats are a fine powder. I’ve used both with good success, but blender is my favorite because it tends to go a bit faster.

THAT’S IT! Now, you’re ready to make your own oat flour…

HOW TO MAKE OAT FLOUR:

It’s SO easy to make oat flour! All you need to do is:

  1. Measure out quick or rolled oats
  2. Pour oats into a blender or food processor
  3. Cover and blend until you’ve got a fine powder, about 15-20 seconds. (After blending, I recommend scraping down the sides or shake the blender jar a bit so you don’t miss any oats. If you notice you missed some, blend again till it’s all smooth.)
  4. Pour oat flour into an airtight container or use right away!

FAQ + TIPS & TRICKS FOR HOMEMADE OAT FLOUR:

HOW MUCH OAT FLOUR DO YOU GET PER CUP OF OATS? It will depend a bit on how compacted your oat flour is when you measure and whether you used rolled or quick-cooking oats, but a general guideline is 1 cup of rolled oats makes just over 1 cup of oat flour. 

IS A FOOD PROCESSOR OR BLENDER BETTER FOR MAKING OAT FLOUR? I’ve used both with great success, but I typically use my blender because it’s faster and easier for me. Food processors will take a bit longer and may not produce results quite as fine as a blender, but will totally work. It’s up to you!

IS OAT FLOUR GLUTEN-FREE? It is *IF* you use certified gluten-free oats. Oats don’t contain wheat gluten, but growing & farming processes often cause cross-contamination, which can cause reactions in Celiac or gluten-intolerant folks. You can avoid this by buying certified gluten-free oats. We like Bob’s Red Mill, Thrive Market, Trader Joe’s, and One Degree Sprouted oats.

HOW TO STORE OAT FLOUR + HOW LONG OAT FLOUR STAYS FRESH. At a minimum, you’ll want to keep your oat flour in an airtight container to keep it fresh. It’ll keep about 1 month at room temperature, about 2 months in the refrigerator, and about 3 months in the freezer.

WHAT KIND OF OATS DO YOU USE TO MAKE OAT FLOUR? I recommend rolled oats or quick-cooking oats for making oat flour. Steel-cut oats can strain your blender or food processor motor and burn it out if you’re not careful.
