Here is the Optimus Prime cake I made for my son Zack's 4th birthday. The party was last Sunday. I though I would post it because I had a really hard time finding cakes to use as an example. I also had a hard time finding pictures of the All Spark, which I thought was funny, since that was the whole point of the movie. I did the Optimus out of chocolate cake, my mom's buttercream frosting recipe and all of the windows and gray stuff were out of royal icing - which hardens. I did not use any fondant, because while it looks great, most people do not seem to like the taste/texture of it. The All Spark is out of yellow cake and covered in buttercream. I then made chocolate wafer cookies to the size needed and covered them in a powder sugar frosting that I swirled with brown and black food coloring and then poured onto the cookies. Once the frosting starded to set I pushed some texture into it with some stuff from around the kitchen. After it dried hard, I drew on it a little with food coloring markers and then attached them to the cake cube. I hope you enjoy the pix and would like to hear what true Transformer fans really think.
