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:

    I invested in my health and bought a Vitamix that pulverizes oats. I like to duplicate certain products that’s a little costly. I’ve found healthy alternatives to replace for the foods and desserts I love. This recipe is quick and simple and leaves room to experiment

    When substituting oat flour for regular, are the amounts the same?

    What is the difference between regular Old Fashioned oats and gluten free oats? Do some oats have gluten and others not? Also, do you think this flour would work all right in a pie crust? I make a wonderful pumpkin pie with whole wheat flour (pulverized very fine in my Magic Bullet) but I wanted to try gluten free this year.

      The only difference between regular oats and certified gluten-free oats is the where they are grown. Gluten-free oats are not grown near any crops that contain gluten, so that the chance of wheat accidentally being included with the oats during the harvesting process (from wheat seeds that blow into an oat field and grow amongst the oats) is greatly reduced.

      You can substitute oat flour for wheat flour, but I have never tried it when making a pie crust. I would recommend doing a trial run…now I want to try it! Let me know how it turns out.

    Glad I ran across your site, I am visiting my grandchildren. Although my kids eat healthy, I often see that the little ones would rather have more snacks than breakfast. I am trying to make up a healthy blueberry oatmeal cookie recipe without sugar or flour so my kids can feel good about giving them cookies if they don’t feel like breakfast. They do good without sugar. This oatmeal recipe will come in handy. I am always on auto pilot when I visit them. Can’t believe I had that much energy when I had kids. Good postings here.

      What an awesome Grandma! Healthy breakfast cookies are a brilliant solution! You are right, find healthy ways to feed kids the things they want and call them by names that will make them want to eat them and you can get a lot more nutrients into their little bodies.

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.
