Shortbread Sandwich Cookies

Directions

1. Place ungreased baking sheets in the refrigerator. In a large bowl, cream butter and confectioners' sugar until light and fluffy. Beat in vanilla. Combine flour and baking powder; gradually add to creamed mixture and mix well.
2. Using a cookie press fitted with a ribbon disk, press dough into 2-1/2-in.-long ribbons on chilled baking sheets. Bake at 375° until edges are lightly browned, 6-8 minutes. Cool for 1 minute before removing from pans to wire racks to cool completely.
3. For filling, in a small bowl, cream butter and confectioners' sugar until light and fluffy. Dissolve coffee in hot water; add to creamed mixture and mix until smooth. Spread 1 teaspoon filling on the bottom of one cookie; top with another cookie to form a sandwich. Repeat.
4. In a microwave, melt chocolate chips and shortening; stir until smooth. Dip one end of each cookie into chocolate, allowing excess to drip off and then in nonpareils. Place on waxed paper-lined baking sheets until set.
