Are Oats Gluten-Free?
No, not all oats are gluten-free.
Even though oats are naturally free of gluten, there is a high risk of cross-contaminating with wheat during the manufacturing process. This means that regular oats may contain gluten.
So if you want to make gluten-free baked goods, it’s very important to use certified gluten-free oats (I like Bob’s Red Mill).
Certified gluten-free oats are safe for people with Celiac disease because they’re made in a separate facility. They’ve also been tested to ensure they contain less than 20 ppm gluten.
So when in doubt, look for the gluten-free label on any oat flour you buy at the grocery store! You can also make homemade oat flour in a food processor or high-speed blender, but you’ll need to buy gluten-free oats to make them.

Ingredients
Oats are the only ingredient you need to make oat flour! You can use old-fashioned oats (rolled oats), quick-cooking oats, or steel-cut oats.
Just keep in mind that the type of oats you use will result in a different amount of oat flour.
Quick-cooking and old-fashioned oats yield a little less than one cup of flour, while steel-cut oats will make closer to two cups of flour. (Steel cut oats are also a bit harder to blend.)
How to Make Oat Flour
- Fill your blender or food processor about halfway with oats.
- Blend until the oats turn into flour-like consistency, with no whole oats. This could take anywhere from 30-60 seconds.
- Use oat flour immediately for baking, or store for later use.
