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, oat flour retains the bran, germ, fiber, protein, vitamins, minerals, and unique phytochemicals found in whole oats. Its naturally mild, slightly sweet flavor and fine texture make it one of the most versatile whole-grain flours for baking.

Unlike refined wheat flour, oat flour contributes dietary fiber, plant protein, and beneficial compounds such as beta-glucan and avenanthramides. It creates tender baked goods with a delicate crumb and works especially well in muffins, pancakes, waffles, cookies, cakes, quick breads, and fruit crisps. Oat flour can also be made at home in just a few minutes by blending rolled oats in a high-speed blender.
