Preheat oven to 350°. In a large bowl or mixer, cream together butter, shortening, and sugars, eggs, and vanilla. Beat for 2-3 minutes. Add pudding mix and mix again.

In a separate bowl, combine flour, baking soda, and salt. Add this mixture to the wet ingredients and mix just until combined. Add oatmeal and Craisins (See Note for add-ins.) and stir in with a spoon, just until barely combined.

Drop by rounded spoonfuls or cookie/ice cream scoop onto prepared cookie sheets. Bake 9-11 minutes or until the edges just barely begin to turn a light golden brown. Don't overbake.
