Is oat flour gluten free?

Pure oat flour is naturally gluten-free because oats contain no gluten proteins. However, like whole oats, standard commercial oat flour is prone to gluten cross-contamination if processed on shared factory equipment that handles wheat, barley, or rye grains.

For individuals with celiac disease or non-celiac gluten sensitivity, buying certified gluten-free oat flour is essential. Certified brands utilize dedicated farming, harvesting, and milling machinery tested to maintain strict safety standards. You can also make your own gluten-free oat flour at home by grinding certified gluten-free rolled oats in a clean high-speed blender or food processor until powdery and smooth.
