    Refer to photo or related blog link for a visual. Outline Spiderman's face in a 5-inch circle on a piece of parchment paper. Place the image face up on the cake surface and prick the outlines through the paper into the cake with a needle to leave tiny holes in the buttercream. Remove the parchment paper. Pipe black frosting along the pricked outlines, and fill the outer border of Spiderman's eyes. Fill the inner eyes with white frosting.

    Use the black frosting to pipe spider web over the sides of the cake. First pipe long vertical black lines, then connect the web with curved black lines.
