Delicate Mint Thins

Directions

1. In a large bowl, cream butter and sugar until light and fluffy. Beat in egg yolk and vanilla. Combine the flour, baking powder and salt; add to creamed mixture alternately with milk, beating well after each addition. Stir in mint. Shape into two 8-in. rolls; wrap each in plastic. Refrigerate for 2 hours or until firm.
2. Unwrap and cut into 1/4-in. slices. Place 1 in. apart on greased baking sheets. Bake at 350° for 8-12 minutes or until edges are golden. Remove to wire racks to cool.
3. In a microwave, melt chocolate chips and shortening; stir until smooth. Dip each cookie halfway; allow excess to drip off. Place on waxed paper; let stand until set.
