Oatmeal S'more Cookies

1/2 cup butter, softened
1/2 cup shortening
1 cup packed brown sugar
1/2 cup sugar
2 eggs
1-1/2 teaspoons vanilla extract
3 cups all-purpose flour
1 teaspoon baking soda
1/4 teaspoon salt
1-1/2 cups old-fashioned oats
1 cup (6 ounces) semisweet chocolate chips
1 cup miniature marshmallows

In a large mixing bowl, cream the butter, shortening and sugars. Add eggs, one at a time, beating well after each addition. Beat in vanilla. Combine the flour, baking soda and salt; gradually add to creamed mixture. Stir in the oats, chocolate chips and marshmallows.

Drop by heaping teaspoonfuls 2 inches apart onto greased baking sheets. Bake at 350° for 9-11 minutes or until golden brown. Cool for 1-2 minutes before removing from pans to wire racks to cool completely. [Note from Jessica: Don't wait long to remove from pans as the marshmallows make them stick.] Yield: about 6 dozen.
