Oat flour is a type of flour made from finely ground whole oats. It’s commonly used in baking as a gluten-free alternative to wheat flour, though it behaves a bit differently in recipes. Oat flour is often used to: Add a mild, slightly sweet, nutty flavor. Improve moisture and tenderness in baked goods. Increase nutritional value (it's high in fiber, especially beta-glucan). Make recipes gluten-free, if processed in a gluten-free facility. Common Uses: Muffins Pancakes Cookies Quick breads (like banana bread) Gluten-free cakes As a portion of the flour in multi-flour blends
