Oat Flour Substitutions

Flavor: The mild, naturally sweet oat flavor disappears entirely. All-purpose flour is completely neutral, so recipes that relied on oat flour's subtle sweetness may taste a bit flat. Consider adding a tablespoon of honey or brown sugar to compensate.

Texture: Oat flour produces a distinctly soft, moist, and slightly dense crumb that all-purpose flour cannot replicate. Your baked goods will be lighter and airier with AP flour, but you'll lose that characteristic tender, almost cake-like quality. Cookies will spread more and be crispier rather than the chewy softness oat flour provides.
