Easy How to Make Your Own Oat Flour Recipe

Last Updated on August 8, 2023 by Gabby Hatten

Oat flour is not something most people keep stocked in their pantry, that is unless you have celiac disease or choose to keep a gluten free diet. While it’s not something I personally use often, there are recipes I create that absolutely need it- all purpose flour just is not the same. Lucky for you, if you need oat flour for a one off recipe and don’t want to buy a whole bag, you can make your own oat flour with pantry staples!

Steel-cut oats, rolled oats, or old-fashioned oats work best.You don’t want to use quick oats as they will have a chewy texture and we need a fine powder. To blend, you can use a food processor, high-speed blender, or immersion blender. I personally use an immersion blender because it is all I have at the moment. I wouldn’t do more than a cup of oats at a time. I noticed mine was getting hot and it was making the flour stick to it. While most steel cut oats are inherently gluten free, you’ll want to make sure you look for certified gluten-free oats if you plan to bake for anyone with celiacs. Storage is simple, it needs to be kept in an airtight container. You can refrigerate it to extend shelf life, but I’ve never kept it for longer than a month as I make small batches.

DIY Oat Flour 

If you want a more nutty flavor, use whole oats. Add your oats (whatever kind of oats you choose to use) to the blender and blend until completely pulverized. You should have a very fine flour consistency. For best results when using an immersion blender, do no more than one cup at a time. For one cup of flour I had to blend about two cups of oats. 

My favorite oats to use for this are from my local Publix grocery store, I love their Greenwise brand! They’re organic and I always have them in my pantry. (remember, no quick-cooking oats will work)

Now that you’ve made your very own gluten-free flours, let’s put it to use! See my oat flour recipes linked here. Don’t want to make your own flour but want to make this recipe? I love Bob’s Red Mill flour!

I hope this recipe inspires you to tackle some gluten-free baking, as it doesn’t have to be expensive! The easiest way to test it out is pick a recipe you already know and love, and substitute a cup of regular flour for a cup of oat flour.
