Roll into one tablespoon balls and place two inches apart on cookie sheets.
Bake for 8-10 minutes until just lightly golden brown. Cool on cooling racks.
Notes
To make oatmeal flour, place the old-fashioned oats in a food processor and blend until ground into a fine powder.
Use a medium cookie scoop to make your dough balls nice and even.
These cookies will continue to bake just a bit when you take them out of the oven. It’s a good idea to take them out when they look just a bit undercooked to how you like them.
