What Is Oat Flour?

Oat flour is simply ground oats. It has a mild, slightly sweet flavor and works beautifully in muffins, pancakes, and quick breads.

You can:

• Buy store-bought oat flour
• Or make your own by blending rolled oats in a blender until fine

It’s a great gluten-free alternative to all-purpose flour.
