Oat flour comes from the grain of the oat plant. Commercial manufacturers grind it directly from oat grains, and you can make oat flour by grinding oatmeal more finely. Baked products made with oatmeal retain their freshness and moisture longer than those made with wheat flour do. You must combine oat flour with wheat flour to make leavened products, since oat flour does not contain gluten.
