Why can't you susbtitute oat flour for wheat flour 1:1?
Wheat has gluten, and oats have avenin (which are similar proteins).
What is different about avenin that you can't substitute oat flour for wheat flour when baking cookies, breads, etc?
Best Answer
I don't know what you mean by avenin being "similar", but it doesn't behave like gluten at all. Oat flour behaves like any other gluten-free flour and is a poor substitute for wheat flour. You can only use it in recipes which are specifically engineered for gluten-free flours. If you try using it in recipes which rely on gluten, you will fail for certain.
It is somewhat interchangeable with some other gluten-free flours like chestnut or sorghum flour (also buckwheat if you don't need the flavor profile), but gluten-free recipes being fickle, you always run a risk of failure, unless you have a pretty forgiving recipe like crepes. It is not a good substitute for nut-based flours, and is a mealy, not waxy starch.
