Smooth ice 7" cake with white buttercream. While still wet apply edible image to side. Depending on exact size of cake you may have to trim height of edible image.

Fill pastry bag fitted with #4 tip with chocolate buttercream and pipe small ball trim around top and bottom edge of cake. Sprinkle top of cake with edible gold flakes.

Melt cocoa dark candy coating and fill small parchment cone. Use a sheet of acetate to pipe designs on. Pipe at least 12 small swirl designs for cupcakes and edge of cake. For each swirl pipe 3 "C's" and make sure they touch in as many places as possible. Allow chocolate to set and carefully peel back acetate. If chocolate pieces are breaking pipe a slightly thicker line and make more contact points. Place a chocolate swirl design on each buttercream iced cupcake. Use the buttercream pastry bag pipe 5 small mounds of icing around edge of cake. Place a chocolate swirl design standing straight up in each mound of buttercream. Use the corner edge of a piece of paper to draw template for chocolate topper. Make several "C's" that connect in several places and form right angle along corner of paper. Put template under acetate and pipe at least 5 of the same pattern. Allow to harden completely. Carefully release from acetate. Gently hold one piece standing straight up and run a bead of chocolate along center edge, quickly attach a 2nd piece at slightly less than 90 degree angle. Keep piping beads of chocolate along center line and attach each chocolate design. After all 5 are standing up run additional lines of chocolate along center line between each piece to make design stronger. Carefully pick up and place on top of cake.
