Measure oatmeal and blend in a blender to a fine powder (perhaps oat flour would work). Cream together the butter and both sugars. Add eggs and vanilla; mix together with flour, oatmeal, salt, baking powder, and soda. Add chocolate chips, Hershey Bar, and nuts. Roll into balls and place two inches apart on a cooking sheet. Bake for 10 min. At 375 degrees. Makes 112 cookies (10 dozen).
