What is oat flour?

Oat flour is made from ground oats or whole oat groats that are ground in a mill into a soft powder. A food grinder, mill, blender, or food processor works to make oat flour.

This flourless whole grain makes a wonderful substitute for flour in baking, especially gluten-free baking like this healthy chocolate bundt cake, almond flour blueberry muffins, and my healthy donuts recipe.

Is all oat flour gluten-free?

Not all oats are gluten-free, so when looking for oats and oat flour in stores make sure the packaging says "certified gluten-free". Many oats and oat flour is either grown in a cross-contaminated farm with wheat, or processed in a facility that uses wheat and gluten. To ensure that your oats are gluten-free they have to specifically say that.

How to make oat flour at home

Add old fashioned rolled oats, quick cook oats, or steel cut oats to a high speed blender or food processor. It only takes about 15 seconds to blend the oats into flour. Turn it on and blend just until it becomes a flour. If you over blend it may start to clump.

Tips: A food processor may take a little longer than 15 seconds. I make my oat flour with a Vitamix and it works like magic to grind the oats quickly and super fine.

Storing

Store the homemade flour in a sealed airtight container in a pantry for about 1 month. To see if it has gone bad, smell it and it should smell like fresh oats. If it has a rancid odor then it has gone bad.

1 cup of oats equals how much oat flour?

How much oat flour does one cup of oats make and can I make it out of oatmeal? One cup of rolled oats or quick cook oats makes a little over 1 cup of oat flour. You can also use steel cut oats which makes about 2 cups of flour.

Make this recipe in small batches or do large batches so you have enough cups whenever you need.

Where can you buy oat flour?

You can find ground oats, or oat flour in most grocery stores. But if you have no time to get to the store it can also be ordered on Amazon. Bob's Red mill makes wonderful gluten-free oat flour (affiliate).

How to use oat flour in recipes

Oat flour does not measure the same as all-purpose flour. It is much lighter and not as dense so more is needed when used as a substitute for all-purpose flour. So when using oat flour in place of all-purpose flour make sure two things:

1. There is a binder such as eggs. Flax and other egg substitutes with just oat flour may not bind as well during baking. Using eggs in a recipe helps the flour to stay together.
2. More oat flour will be needed in place of regular flour. Play with the recipe a bit, because oat flour is not a 1:1 ratio. Additional oat flour will be needed so play around with the texture of the batter.

Tip: When using oat flour in baking, let the batter set for 10 minutes before cooking. This allows time for the oats to absorb the liquid and flavors.
