Oat Flour

Leaning into healthiness right now and that means looking for more options for my baking projects like banana bread and muffins. I could easily grab a bag of oat flour or gluten free flour from the store but I have a ton of oats in my pantry that need to be used up. This easy Oat Flour is so fantastic and simple.

If you ever bought Oat Flour at the store you already know it’s on the spendy side but it’s so much better for you than regular wheat flour and, if you buy a certified gluten-free oat product, you now have homemade gluten free flour.

If you ever wanted to know how to make Oat Flour at home, you are in luck because it takes about 5-10 minutes….tops and it’s a great substitute for regular flour in so many of my recipes.

What is Oat Flour

Oat Flour is a whole grain, nutritious flour made out of oatmeal. It has the exact nutritional make up as oatmeal because it’s just oat that have been processed until fine and powdery.

Rich in nutrients such as manganese, copper, biotin, vitamin B1, molybdenum, phosphorous, magnesium, chromium, and high in fiber, oat flour is a great alternative to many other flours and is gluten free. It has a nutty flavor and creates a tender crumb in baking recipes.

What Type of Oats to Use to Make Oat Flour

For best results, rolled oats and even quick cooking oats can be used to make oat flour. You can use steel cut oats, as well, but the processing time will be much longer since they are more dense.

How To Make Oat Flour

This Homemade Oat Flour recipe starts with just 2 cups of either regular old fashioned oats or instant oats.

Place the oats in your food processor and process until powdery…..like flour.

You’ll still have a few grainy pieces and that’s totally cool…you can either sift them out or leave them in. I think they add a nice nutty texture to baked goods but if smooth is where you’re heading a quick sifting will lift them right out.

How To Store Oat Flour

You can store oat flour in an airtight container at room temperature if using often.

Oat flour can go rancid quickly so if you’re not planning to use all of it within a month, freeze it until ready to use. Allow the oat flour to come to room temperature before using.

How To Use Oat Flour

I love to sub out the regular flour in these Oatmeal Raisin Cookies for an extra oat-y cookie or you can nix the regular flour in this pancake mix with your homemade oat flour for quick weekday Oat Pancakes! Your kids won’t even know you made the switch!

Tips for Substituting Oat Flour in Baking

Because oat flour doesn’t contain gluten, it will bake differently than a wheat flour. Some recipes may become more dense than fluffy because the absence of gluten.

It’s best to weight the oat flour when baking to ensure accuracy because oat flour is much lighter than all purpose flour and whole wheat flour. Don’t substitute oat flour cup for cup or your baked goods will not rise properly.
