Welcome back to the Beaming Baker Baking Basics series!! At least, that’s what I’m tentatively calling it. 😉 I’m kinda feeling the alliteration, are you?

We kicked off this series with How to Make a Flax Egg. I know, super sexy, thrilling stuff. Some of you may have already known how to make a flax egg and just wondered about the nuances, wondered if you could swap one with chia eggs, or were just learning about it for the first time. Either way, it was tons of fun and eye-opening for us all!

Next up on the basics list: How to Make Homemade Oat Flour. I’ve often gotten questions like, “Where do I find oat flour?” “Can I make it at home?” “What kind of oats do I use?”

I’m going to first cover the steps on how to make homemade oat flour, then I’ll go over a few frequently asked questions. Sound good? Let’s get started!

STEP ONE

Add gluten free rolled oats (otherwise known as “old-fashioned oats”) to a food processor or blender. I like to use a food processor because it can blend more thoroughly and evenly throughout.

STEP TWO

After the first few rounds of blending, the oats will look like this. Some oats are still whole, others are beginning to turn into flour.

STEP THREE

Blend more, making sure to periodically scrape down the sides of the processor. After about a minute or two, no whole oats remain. Much of the mixture has turned to flour. However, if you take a closer look, flakes of oats still remain. Using a spoon, scoop up some flour and look closely. The more oat pieces that remain, the grittier and chunkier the flour will be in your recipe (which you usually don’t want). Blend until you reach Step Four.

Now you’ve got it! The flour must be fine all the way through. Yes, it’s perfectly normal to have a few flakes of oats here and there. But try your best to grind the flour as finely as possible.

STEP FIVE

Use it! Make sure to measure the oat flour after you’ve ground it and not before, when it’s in whole oat form. Recipes below. 🙂

 

Common Questions About Oat Flour

What is oat flour?

Oat flour is a nutritious, unrefined flour made from just one whole ingredient: rolled oats. It’s a great baking flour for gluten free and vegan recipes. It has a fairly neutral taste and absorbs flavors really well.

Where do I find oat flour?

You can find gluten free oat flour online here! Oat flour is usually located in the health food section of your local grocery store. In stores like Trader Joe’s and Whole Foods, you can find it in the baking section, usually near the allergy-friendly products.

Can I just make my own oat flour to use in a recipe?

Yes! Be sure to make more than the recipe calls for. 1 cup of rolled oats does not equal 1 cup of oat flour. There’s about a 1 tablespoon difference per cup. Most importantly, make sure to grind the oats until they’re very fine. Coarse/crumbly oat flour is not ideal to use in recipes (unless noted). Coarse oat flour will result in crumbly baked goods.

Can I substitute oat flour for other kinds of flour and vice versa?

Yes and no (I know, what an annoying non-answer). Oat flour can sometimes be substituted with gluten free all purpose flour and whole wheat flour, with a 1:1 ratio. However, you should always proceed with a recipe substitution with caution. Unexpected results may occur, as that recipe was not developed for your substitution. Good luck!

    Where was this post when I was buying expensive oat flour—and often having difficulty even finding it in stores? About six months ago I learned how easy it was to make and will never buy it again. I try to use steel cut rather than rolled oars since the steel cut is less processed. It takes just a drop longer and it may be a tiny bit coarser, but still works.

    Thanks is for the oat flour “scoop”!! I just returned from a holiday in Kerala, India where they eat a dish called Puttu for breakfast. It’s made from steamed roasted rice flour, shredded coconut and served with bananas. I fell in love with it, but it difficult to relocate at home as it hard to find or make the right kind of roasted rice flour. However I just stumbled upon a version made with oat flour yesterday and then BOOM, your post came in. So I will be making Puttu with oat flour this weekend. So cool!!!!! ☺
