Preheat oven to 350°. Grease 2 (8-inch) round cake pans, and dust with cocoa. Set aside.
Beat cake mix and next 7 ingredients at low speed with an electric mixer 1 minute; beat at medium speed 2 minutes. Fold in chopped chocolate. Pour batter into prepared pans.
Bake at 350° for 30 to 32 minutes or until a wooden pick inserted in center comes out clean. Cool in pans on wire racks 10 minutes. Remove from pans to wire racks, and cool completely on wire rack. Wrap and chill cake layers at least 1 hour or up to 24 hours.
Using a serrated knife, slice cake layers in half horizontally to make 4 layers. Place 1 layer, cut side up, on cake plate. Place 1/3 cup of the frosting in a piping bag; pipe a ring of frosting around the edge of the first cake layer to create a border. Spread one-third of cheesecake filling over cake inside frosting ring; top with one-third of cherry pie filling. Repeat procedure twice with frosting borders, remaining cheesecake filling, and cherry filling. Place final cake layer on top of cake; cut side down. Spread remaining chocolate fudge frosting on top and sides of cake. Cover and chill in refrigerator until ready to serve. Garnish, if desired. Store in refrigerator.

I have made this many times, always to rave reviews. It is the pefect "wow" cake when I don't have loads of time to be fussy.
Unlike some other reviewers, I appreciate a few quick recipes thrown in with the scratch recipes. Different times of my life need both options.
