The longer you have been doing something, the more likely you are to  do it on autopilot. When I was a manager, I used to have the second newest person train the newest person because she/he was the person that was most likely to still think about each step and remember to pass on ALL of the details. I was reminded of this recently when one of my children looked at my Egg Free Almond Cookies and said, “we have oat flour?” Well, technically no, we didn’t have oat flour. And then I realized that I forgot to share an important money saving tip!

Oat flour is expensive, but you can make your own very easily using old-fashioned (NOT quick cook) oatmeal. I use gluten-free whole grain oats, which allows me to create gluten-free oat flour, which is something I have never been able to find in our stores.

To make oat flour, add one cup at a time of old-fashioned or steel cut oats to your blender.

Pulse on high until it the oatmeal becomes the consistency of flour. If you don’t have a very powerful blender, let the blender come to a rest between pulsing it and use a spoon to stir the oats. I have a plain, 15 year old Osterizer blender and it takes me less than a minute to make oat flour:

    Why can’t you use the quick 1 minute oatmeal? That’s all I have. Aren’t the steel cut oats expensive too. In that case, wouldn’t I just buy the oat flour in the store? Just asking. Curious. Thank you for this info!

      One minute oatmeal has already been partially cooked, so the resulting flour will not work the same in recipes. You can find inexpensive whole oats like Quaker Oats old-fashioned oats or the equivalent store brand. I buy certified gluten-free oats, which happen to be steel cut and are more expensive than Quaker Oats, but still less expensive than oat flour.

    I am so glad to find this informtion I have a wheat allergy and am so tired of constantly having to clear my throat and blow my nose if I want a sandwich or other treat. I am eating oatmeal twice a day to bring my cholesterol down to a better number. I refuse to take statins.

      So glad you decided to skip the statins. I am still suffering 2 years later after being on statins for just 3 months. When you get tired of eating so much oatmeal, try food-grade diatomateous earth. I bought mine on Amazon.

    Thank you for telling us how to do something so simple. I live in a rural area and am so frustrated trying to find all the different flours every time I want to try something. I am new to this gluten free diet, but I use to love to bake. I hope that love comes back with a few people like you helping.

    I was just browsing for quantities to make oat flour and ran across your site. I want to make an old favorite pizza dough recipe that my kids loved back in the ’70s. It uses 3/4 c oat flour, which I always made in the blender.

    No! You are absolutely not the only person who runs on auto-pilot! LOL

    I love this idea. What kinds of recipes can you use your oat flour in? Does it work in savory dishes?

      I want to use for a gravy or sauce base instead of white flour or make a nut bread with it or muffins.

    I make most of special flours in home as they are expensive to buy and difficult to get.

    I do the same thing except I have a small coffee grinder that is dedicated just to making oat flour. I have even labeled it OAT FLOUR ONLY in my kitchen. Good tip.

      I don’t plan on buying a high priced blender right now, maybe in the future. But I do have a coffee grinder and will be trying it out with that. Thanks for the tip Auntie T.

Welcome. I'm Alea!

On Premeditated Leftovers I share simple recipes made with whole foods, practical shopping tips, time saving techniques, and meal planning strategies. I also share tips for minimizing food waste, so more of the food that is purchased ends up on the table.

While volunteering as a budget counselor, I realized that food is the element of most people’s budgets where they have the greatest control. I set out to develop low-cost recipes from scratch to prove it’s possible to create delicious meals on a limited budget. Eating well while spending less is about more than just creating recipes using inexpensive ingredients; it’s about creatively combining ingredients so you don’t feel deprived and are inspired to stick to your budget.
