Preparation

• In a large bowl, cream the butter, shortening and confectioners' sugar until light and fluffy. Beat in vanilla and maple flavoring.
  Combine the flour, oats and salt; gradually add to creamed mixture and mix well.
  On a lightly floured surface, shape dough into 1/2-in.-wide logs. Cut into 2-in. pieces. Place 1 in. apart on ungreased baking sheets.
  Bake at 325° for 15-18 minutes or until set and very lightly browned. Remove to wire racks to cool.
  Mix melted chocolate and milk; stir until smooth. Dip one end of each cookie into chocolate; allow excess to drip off. Roll in walnuts. Place on waxed paper until set.
