Oat Flour Overview

Oat flour is made from finely ground oats and is commonly used in baking for a soft, slightly sweet texture. Despite being perceived as “healthier” than white flour, oat flour is still high in carbohydrates and is not suitable for low-carb or keto baking. For diabetic-friendly baking, portion size and recipe structure matter, but oat flour remains a high-carb ingredient.
