There are a lot of gluten free or "flourless" recipes available today that call for oat flour. While it's pretty widely available at most grocery stores, you don't need to buy it! Oat flour is relatively expensive when compared to using regular all-purpose flour and there is a much cheaper alternative: you can make it yourself.
Making your own oat flour is one of the easiest things you can do and requires just one ingredient, oatmeal. It also requires one appliance that almost everyone has, a food processor. You could also use a high speed blender if you have one.
If you are gluten-intolerant or have celiac disease, make sure you use certified gluten free oats. If you can tolerate oatmeal just fine, use any steel cut or old fashioned oats.
I store my oat flour in the freezer to extend the shelf life but you can keep it in an airtight container for at least a few weeks and up to a few months at room temperature.
