How to Make Quick Oats and Oat Flour

There’s nothing magical about these instructions and many of you probably know how to do this already. I’m not even entirely convinced that this will save much money, as there isn’t much price difference in whole oats, quick oats, and oat flour.

However, here’s why I find these tips to be beneficial:

They save my brain. And also storage space in my pantry, but my brain is obviously a much bigger issue now. Anything that saves my brain makes me so, so happy. (Hello, 40’s. I love you truly. But why do you make it harder to think straight? I think it must be because my children are coming and going more than they used to and also, I have more profound, wise thoughts floating through so I have less space for silly little unimportant things like remembering where I put my phone.)

So see? If I order Whole Rolled Oats, then I can make my own Quick Oats and Oat Flour as needed. My brain is thus saved from ordering three different items and making sure I have them on hand. It takes turning 42 to come up with stuff like this. Be amazed.

How to Make Quick Oats and Oat Flour

Why do I need Quick Oats? Well, I rarely do, except for when I make Homemade Instant Oatmeal – which is da bomb. And Oat Flour? Well, that’s just nice to add to muffins or pancakes sometimes when I want to include a variety of grains. I guess that’s another nice reason to not buy each of them individually. I mostly use whole rolled oats. The rare occasion I need quick oats or oat flour, I can just make it quickly with my whole oats.

So, how to make these delightful oat products? It’s as easy as putting Whole Oats into your blender and turning it on. Whirl for a few seconds until quick oats are formed. Whirl for a few more seconds until oat flour appears. It’s almost the easiest thing in the world.

With that, I will tell you that if you’ve never needed this information before today, you will need it tomorrow because I have a Monster Cookie Bar recipe to share that includes no flour but it does include both whole oats and quick oats. Get out your oats and your blender. You’re going to want to make these bars.

What do you prefer to use at your house? Whole oats or quick oats? Do you use oat flour much?

    Never knew about the quick oats but definitely used the oat flour trick beforehand. And if you don’t mind scratching up your blender container some, you never need to buy powdered sugar again. Same deal: just put it in the blender, blend away and measure as needed. You probably shouldn’t do this ahead of time because it won’t be as fluffy as you need it if you let it sit for a while (more than a week?).

    Oh, and if you buy peaches and then get sick and no one preps them for the deep freeze, you can make peach-sauce in the blender too with your extra ripe peaches. :) It goes in the freezer just fine.

    I use quick oats to make pre-bagged instant oatmeal in individual portions to take to work for those days when I don’t have time to make breakfast at home. I add some sugar, raisons, craisons, and a pinch of salt. I just pour it in a bowl and heat some water in our lunchroom to have a quick breakfast at my desk.

    I love oat flour in muffins and quick-breads. I use it 2-1 with all purpose flour. It does NOT work well in pie crusts, I’ve found.

    For oatmeal, we prefer steel cut oats. I make a big batch on Sunday, then portion it out for heat and eat breakfasts. For baking applications I use Bob’s Red Mill Extra Thick Cut Rolled oats. My newest obsession is Muesli, a cereal similar to granola, but with far less sugar. The recipe I use calls for rolled oats, slivered almonds, coconut, cinnamon, vanilla, salt, coconut oil and maple syrup. Super easy, kid approved!

    I made oat flour this way the other day, because I wanted to make your No-Bake Chocolate Fudge bites recipe, and I didn’t have any coconut flour. The oat flour substituted well, I think. They’re all gone….so they must have been good!

    Just earlier today I was making baked oatmeal and it called for both rolled oats and quick oats, and I only had rolled. I was like, “I wonder if I could just put rolled oats in the blender for a little bit . . . “. :)
