First, make a cake (crack three eggs in a bowl, bust the yolks, mix cake and water and cake mix in, put it in the oven.) Like you do with cake pops, crumble the cake apart and get chocolate icing and mix it up and make a circle shape on the top.
While you're waiting for the cake to harden, make gingerbread people cookies and decorate them like little kids.
When the cake is hardened, decorate it (make sure you have enough frosting) and stick the gingerbread people to it with icing.
Take a picture and eat the cake.
