Preheat oven to 375 degrees F. Either lightly grease or line cookie sheets with parchment paper or use the Silicone Baking Mats to prevent the cookies from sticking.
Make a powder out of the rolled oats by putting small amounts into the blender or food processor at a time.
In a large bowl, combine powdered rolled oats, flour, salt, baking powder, and baking soda.
In another large bowl, blend butter, granulated sugar, and brown sugar until light and creamy; stir in eggs and vanilla extract. Add the flour mixture; stir until well blended. Stir in chocolate chips and nuts.
Roll dough into golf-ball-sized cookies. Place 2 inches apart onto prepared cookie sheets. Bake 15 minutes or until light brown. Remove from oven and cool on wire cooling racks.
Freezing the Dough: You can freeze this dough. Form the dough into balls and place on a parchment-lined baking sheet. Freeze and then place the balls of dough in a plastic bag, seal, and freeze. When ready to bake the cookies, place the frozen balls of dough on a baking sheet and bake as directed above (you may have to increase baking time a few minutes).
