Using Oat Flour in Your Baking

Common gluten-free flours are the workhorses of gluten-free baking and form the base of most homemade and commercially available gluten-free flour blends. They work best blended with a starch (tapioca, potato, or arrowroot), which lightens the texture and improves browning.

Blend tip: A standard versatile blend ratio is 60% of this flour + 30% tapioca or potato starch + 10% additional flour (chickpea or sorghum improves browning). Add 0.25 tsp xanthan gum per cup of total blend.

Use the Flour Converter for precise substitution amounts, or the Blend Builder to find the right blend ratio for your baked good. See methodology for data sources.
