Enjoy this step-by-step guide on How to Make Homemade Oat Flour, the perfect wheat alternative that is super simple to make. Use this oat flour in muffins, cakes, cookies, and any other recipe that requires flour. And hey, if you are gluten-free, you can enjoy this flour by using certified gluten-free oats!

Making Gluten-Free Oat Flour

Oatmeal does not inherently contain gluten. Not all oats that you buy in the supermarket are gluten-free, however. Cross-contamination when processing or harvesting oats can lead to certain brands not obtaining a gluten-free label. 

If you would like to make gluten-free oat flour, look for old-fashioned rolled oats that are certified gluten-free. Gluten-free oat flour works for so many recipes, from waffles, to cupcakes, to birthday cakes. If you do not have a sensitivity to gluten, you can buy any variety of old-fashioned oats.

Items Needed for Homemade Flour

Why buy oat flour at the store when you can make it at home for much cheaper? Most of us have access to a blender and dry rolled oats. Doing it yourself ensure no filler, chemicals, or any other additives that may be found in commercial flour varieties.

In the development of this recipe, a standard Ninja blender was used to grind the oats into flour. You can also use a personal smoothie blender (which may require blending the oats in batches) or a food processor if you do not have a blender. Be aware that a food processor will not break up the oats as finely as a blender.

Ingredients in Homemade Oat Flour

There is only one simple ingredient needed to make oat flour, which is old-fashioned rolled oats. You can use any brand you like, even a certified gluten-free variety. Avoid using instant oatmeal or quick-cook oats, as they will have a different texture and cook time.

If you are baking gluten-free, you may need additional ingredients, such as xanthan gum. Xanthan gum is a binding ingredient that is meant to mimic gluten. Check with the recipe you are using before adding anything else to your Homemade Oat Flour.

How to Make Homemade Oat Flour

Measure your oats carefully. Add them to your blender.

Blend on high for 3-4 minutes until you have a fine flour.

Remove to a sealed, airtight storage container. Use for baking, coating, frying, or any other needs in place of wheat flour.

Notes: 

Make as much oat flour as you’d like. This recipe works with any measurement of oats.

3 cups of whole rolled oats equals about 2⅓ cups flour. 

Use a blender over a food processor. A blender will give a finer flour than a food processor.

If desired, sift your blended oats before storing to remove any large pieces of oat that have been left behind.

Storage:

Store in an airtight container in a cool, dry area for up to 6 months.
