1. Preheat oven to 350°.
2. Lightly spoon flour into dry measuring cups; level with a knife. Combine flour and next 3 ingredients in a large bowl. Add cherries and 1/4 cup chocolate; make a well in center of mixture. Combine eggs and next 3 ingredients, stirring with a whisk; add to flour mixture, stirring to form a stiff dough. Knead dough until blended.
3. Divide dough in half. Shape each half into an 8-inch-long roll on a large baking sheet coated with cooking spray; flatten each roll to 1-inch thickness.
4. Bake at 350° for 30 minutes. Remove rolls from pan, and cool 10 minutes on a wire rack. Cut each roll diagonally into 15 (1/2-inch) slices using a serrated knife. Place slices, cut sides down, on pan. Bake at 350° for 10 minutes on each side. Remove from pan; cool completely on a wire rack.
5. Combine remaining chocolate and shortening in a small glass bowl. Microwave at HIGH 1 minute or until melted and smooth, stirring once. Dip 1 end of each cookie into melted chocolate, and place on wax paper. Let stand 1 hour or until chocolate is firm.
