Oat flour, which is made from ground oats, can be used in a variety of recipes. It doesn’t contain a caution because it doesn’t behave like wheat flour since it contains no gluten.
As a result, if oat flour is used alone, baked goods will not rise or hold together. Therefore, oat flour must be mixed with other flours in baking, whether you are attempting gluten free baking or just wanting to spice up conventional recipes.
