*disclaimer*
I am in no way taking credit for this recipe, all I did was replace the flour.
This is original recipe http://www.tablespoon.com/recipes/100-whole-wheat-pizza-crust/a1b4fa8d-1f67-4955-8fe7-96649a7186e7
Just replace the wheat flour with 5 cups oatmeal flour (my arm hurts from grinding the oats). Then there you go.
Enjoy folks!
