What is Oat Flour?

It is the magic that results from blending up oats into a fine flour! It’s gained in popularity in recent years making itself into everything from Oat Flour Pancakes to Rich & Oat Flour Brownies!

You can buy your own oat flour, which is what I usually do, but if you can’t find it in stores or online, it’s so simple to make your own! All you need is some rolled oats and a blender or food processor!

Why Do We Love Oat Flour?

If you’re looking for a gluten free option, oat flour is great because it acts a lot like a traditional flour. It rises and makes for deliciously fluffy baked goods!

What Kind of Oats to Use

I tend to use gluten free rolled oats. Rolled oats blend up beautifully into a powdery, flour that we can use in our recipes!

If you try to blend quick oats, steel cut oats, or thick cut oats into a flour, it will result in mealy, bigger pieces and won’t blend quite as nicely. Plus those oats won’t react the same as rolled oats in recipes and will change the texture of your final dish.

Taste & Texture

In my opinion I find it to be a bit sweet making it one of my favorite flours to use for cakes.

The texture is soft and powdery and when it is baked it makes for really fluffy baked goods. A word of warning: as magical as it seems, if you use too much it can be pretty dry.

Can I Sub it in for All Purpose Flour?

Generally I tell people to just go find a similar recipe that uses oat flour so you can BE SURE it works. But, if you want to do some experimenting, I would probably use about 3/4 cup for every 1 cup of all-purpose flour.

Can I Sub it in for Almond Flour?

Generally I tell people to just go find a similar recipe that uses oat flour so you can BE SURE it works. But, if you want to do some experimenting, I would probably use about 1/2 cup for every 1 cup of all-purpose flour.

How to Make Oat Flour

It’s easy! All you need is some rolled oats, a blender, and five minutes!

Measure. Grab your jar of rolled oats and measure them out! I like to use 1 cup at a time so the blade can really get to each and chop them up!

Blend. Use a blender or food processor to process for about 30 seconds until it reaches a soft, powdery mixture. Make sure to not over blend it!

Use! Use it in a recipe or pop it in a baggie or an airtight container to save it for later!

Is it Gluten Free?

Oats are naturally gluten free but cross-contamination happens when they are processed in factories that also process glutinous products. So, they may contain trace amounts of gluten.

As long as you use certified gluten free oats, your flour will be gluten free as well 🙂
