Butterscotch Oatmeal Cookies

1 cup butter' softened                                                      1/3 cup buttermilk
6 tablespoon butter-flavored shortening                             2 teaspoons vanilla extract
1-2/3 cups packed brown sugar                                        3 cups quick-cooking oats
2/3 cup sugar                                                                   2- 1/2 cups plus 2 tablespoons flour
3 eggs                                                                              1- 1/2 teaspoons baking soda
1- 1/4 teaspoon salt.                                                           3/4 cup butterscotch chips
                                                                                        1/2 cup pecans

In a very large bowl, cream the butter, shortening and sugars until light and fluffy. Add eggs, one at a time, beating well after each addition. Beat in buttermilk and vanilla.

Combine the oats, flour, baking soda and salt; gradually add to creamed mixture and mix well. Stir in the chips and pecans.

Drop by rounded tablespoons 3 in. apart onto ungreased baking sheets. Bake at 375 degrees for 10-20 minutes or until golden brown. Remove to wire racks.                                                            
 It makes a big batch, so I  cook half then freeze the other half for a later time.
