I discovered oat flour over 5 years ago when it became clear to me that my stomach felt better when I minimized my gluten intake. I began experimenting with a variety of gluten-free flours in my baking, and oat flour became my instant favorite.

I’ve always loved oats, so it’s no wonder I fell head over heels for the hearty, nutty flavor of the flour. The soft, tender texture that it lends to my oat flour pancakes and healthy zucchini muffins is even more special.

While you can purchase it easily online or in supermarkets, it’s nice to know how to make it just in case you run out. Or if you purchase oats in bulk at Costco, it’s even more cost effective to make it yourself.

Whatever your reasons for making it are, you’ll be happy to know how easy it is to make!

Ingredient notes

  • Rolled oats. Old fashioned rolled oats are the best oats to use for flour as they’ve been steamed then flattened, which ensures that they absorb liquid well and cook quickly. They’re also nice and soft, which makes grinding them into powder very easy. They’re processed less than quick oats, which makes them the best choice.
