This is a chocolate cake with peanut butter frosting, covered in marshmallow fondant. All the features are also MMF. The antennae are the plastic tree forms covered in MMF. The instructions for this cake were from the pbs website. I changed it to use the fondant instead of frosting and candy to decorate. Go to their website for the info on how to make the correct "Buzz" color. My daughter helped decorate, since it was for her party, and the mouth got messed up, but I left it since that was her work.
