Instructions
Homemade Oat Flour - Best Substitute
Use 1 cup whole oats or quick oats to yield 1 cup oat flour, or 1 cup steel cut oats to yield 2 cups oat flour. Measure outs and process them in until a fine consistency, 30 seconds to a minute (depending on the oat type).
More Gluten-Free Substitutes
Use brown rice flour in a reduced amount when substituting for oat flour. Start with ¾ brown rice flour for each 1 cup of oat flour called for in a recipe.
Both white rice flour and cassava flour can be used in a 1:1 ratio when substituting for oat flour in any recipe.
