Oat flour is made by finely grinding whole oat groats or rolled oats into a soft, naturally gluten-free whole-grain flour. Because the entire grain is milled, it retains the fiber, protein, vitamins, minerals, and phytochemicals found in whole oats, including beta-glucan and avenanthramides. Its mild, slightly sweet flavor and fine texture create tender baked goods with a delicate crumb, making it especially useful for muffins, pancakes, waffles, cookies, cakes, quick breads, and fruit crisps. Oat flour can also be made at home in just a few minutes by finely grinding rolled oats in a high-speed blender.
