Cream together the first 6 ingredients in a large bowl. Stir in baking soda, vanilla, and oats. Stir in chocolate chips and M & M’s, and optional ingredients, if using.
Drop by spoonful (however large you want) onto a lightly greased cookie sheet. Press to flatten slightly. Bake in preheated 350° oven for 15 minutes. Let stand on cookie sheet for a minute or two, and then transfer to an air-tight container.
Notes: Do not over-bake. They may look like they are not done after 15 minutes, but trust me, they are, and they will be the most moist cookie you have ever baked.
