Using Oat Flour in Your Baking

Start with a recipe that names this flour. Rice, cassava and coconut use different swap estimates, so keep the flour and starch proportions together when your recipe calls for a blend.

Binder starting point: Keep your recipe's blend ingredients and amounts together. The starting estimate here is 0.25 tsp xanthan gum per cup. Use your recipe’s binder amount for the finished blend.

Use the Flour Converter for estimated flour amounts and any conversion limits, or the Blend Builder to compare recipe-type blend presets. See methodology for data sources.

Storage

Store oat flour in a cool, dry place. For gluten-free baking, choose a product with gluten-free certification; conventional oats can have wheat cross-contact. Some people with celiac disease react to avenin, the oat protein, even in certified oats. Consult your doctor about oats, especially after a new diagnosis. Rough shelf-life estimate: 9 months. Use your bag's date and storage directions when deciding whether to use it.

Certification

Check the specific product: Certification varies by product. A flour category does not establish certification for any bag; check the packaging and maker’s information.
