Learn How to Make Oat Flour to use in gluten-free baking and cooking. A homemade whole grain flour to use in a variety of recipes!

Oat flour is a great gluten-free staple for both baking and cooking.
If you are new to going gluten-free or have been for quite some time, making it at home is a quick and easy way to ensure that you always have some on hand.

Do Oats Contain Gluten?
Oats are naturally gluten-free. But due to the way oats are processed, there is often cross-contamination. This can take place during harvesting, processing, packaging, or in storage.
In order to make sure the oats you are consuming are not contaminated, purchase oats that have been certified to be gluten-free and processed in a gluten-free facility.
Brands that carry certified gluten-free oats include:
- Bob's Red Mill
- Trader Joe's
- Quaker Oats
- Nature's Path
- Arrowhead Mills

How to Make at Home
Is it cheaper to make your own? Making your own flour at home can most certainly be a more cost effective alternative.
Follow the steps below to make your own!
- Add oats to the bowl of a food processor.
- Pulse oats for a few seconds then process.
- Stop food processor once or twice to wipe down sides.
- Process oats until you achieve a fine powdery consistency.
- Store in an airtight container in a cool, dark place.
How do you make it without a food processor? If you have a blender, you can follow these same steps. It is helpful to only fill the blender bowl halfway with oats and blend in batches.
