FAQs

Is oat flour always gluten-free?

Oats do not contain gluten. But oats can become contaminated with gluten during the growing or processing phase. As a result, it’s important to check the label of any oat-based product to make sure it is listed as gluten-free, and it wasn’t used in a plant with grains that contain gluten.

I like Bob’s Red Mill certified gluten-free oat flour.

Can I use quick-cooking oats to make my own oat flour?

Yes, but you won’t need to process the quick cooking oats as long as old-fashioned oats because they are thinner.

Can I use coconut flour instead of oat flour?

It is harder to use coconut flour as a substitute because it absorbs so much more moisture than oat flour. It’s probably best to use another one of the options listed above.
