Learn how to make oat flour with this easy recipe. I love making it at home and having it on hand anytime I want to make my favorite goodies. Oat flour is high in fiber and B vitamins and is naturally gluten-free. I love to use it in my baking, and I am so excited to develop more recipes using this simple ingredient!

How To Make Homemade Oat Flour

I was so surprised at how easy it is to learn how to make oat flour. All you need are some gluten-free rolled oats and a food processor! See also, how to make almond flour.

Baking with oat flour is different than baking with gluten-free flour blends made with rice or traditional wheat flour. Oat flour baked goods will have a chewier and crumblier texture and a cereal-like flavor. I just love it!

Ingredients

• Gluten-Free Old-Fashioned Rolled Oats: Be sure to use certified gluten-free oats. Look for any cross-contamination warnings on the package to ensure there isn’t cross-contamination with wheat. Do not use quick oats or steel-cut oats.

Step by Step Instructions

1. Place the oats in a food processor or high-powdered blender and blend oats into a fine powder.
2. Shake the oats to make sure all the oats get blended into a fine powder.

Recipe Tips and Notes

• Don’t overload the blender or food processor. Process in smaller batches for better grinding.
• To prevent the oat from becoming gummy, I recommend pulsing briefly and avoiding overheating the processor.

Is Oat Flour Gluten-Free?

Oat flour is generally considered to be gluten-free; however, not all oat flour is certified gluten-free. Learning how to make oat flour from certified gluten-free oats helps me to ensure that there is no risk of cross-contamination.

Can You Use Quick Oats?

While you technically can use quick oats to make oat flour, I have found that rolled oats work best because they can be blended to a finer texture.

Is Oat Flour Healthy?

Yes! Oat flour contains lots of fiber, antioxidants, minerals, and vitamins (particularly B vitamins). It is healthier than wheat flour.

Can I Substitute Oat Flour For All Purpose Flour?

Oat flour can be used in place of all-purpose flour in some recipes, but it is not a 1:1 swap, and I have found that it particularly doesn’t work in recipes that contain yeast. I recommend using a recipe that was designed with oat flour as the primary ingredient for the best results.

Storage Instructions

Once you’ve learned how to make oat flour, you can make it in bulk and store it in an air-tight container in a cool, dark place for up to 3 months. You can also freeze oat flour for up to 6 months. Store it in an air-tight container to prevent freezer burn.

Learning how to make oat flour is so simple! With just one ingredient and a food processor (or blender), you’re just 5 minutes away from fresh homemade oat flour, which is great for gluten-free baking.
