Preheat oven to 350F.

Mix together the butter, sugars, rolled oats, whole grains, cereal and eggs in an extremely large bowl.

Add vanilla, baking soda, baking powder, flour and the raisins/nuts/seeds/chips. Mix together. You will need to drop the spoon and use your hands at some point.

Roll into balls and bake on greased cookie sheet for 11-13 minutes.
