Directions Prepare and bake cake mix according to package directions, using a greased 13x9-in. baking pan. Cool completely in pan on a wire rack. Crumble cake into a large bowl to measure 7 cups. In a large bowl, beat butter, cocoa and vanilla until creamy. Beat in confectioners’ sugar alternately with milk until smooth. Add cake crumbs; mix well. Shape into sixteen 1-1/2-in. balls and sixteen 3/4-in. balls. To assemble spiders, insert a wooden or metal skewer through one small cake ball and then halfway through one large cake ball; repeat with remaining balls. Place on waxed paper-lined baking sheets; insert eight pretzel halves into each large ball to form legs. Freeze 2 hours or until firm. In a microwave, melt chocolate chips and shortening; stir until smooth. Dip each spider in chocolate; allowing excess to drip off. Place on waxed paper-lined baking sheets. Remove skewers and attach M&M's for eyes. Refrigerate until set. Yield: 16 servings. Originally published as Edible Arachnids in Halloween Bookazine 2015 2015, p69
