Oat flour is made from finely ground rolled oats, giving it a mild, slightly nutty flavour and a naturally gluten-free composition when certified gluten-free oats are used. One metric cup (250 ml) of oat flour weighs approximately 100 grams or 3.53 ounces. It is commonly used in pancakes, muffins, cookies, and quick breads as a wholesome substitute for plain flour.

Oat flour is much lighter and less dense than plain flour, so substituting by volume rather than weight leads to significant differences in texture and structure. Weighing oat flour in grams ensures consistent, reliable results across recipes.
