My nephew is a huge Transformer's fan and his absolute favorite is Optimus Prime. Funny, though...when he saw this cake his favorite part was all the flames! I think my husband liked the allspark best, but it was his idea so I guess he's biased! Chocolate cake with a peanut butter/chocolate chip cookie filling (that was probably too thick because it was difficult to cut, and iced with vanilla buttercream. I was too lazy to make my own fondant this time (I know...BAD!) so I used Wilton's red, blue and yellow premade fondant to make the flames and Optimus Prime. All the kids wanted to make sure they had a flame or part of O.P. to eat! They didn't complain about the taste, but six year olds don't really know any better. They just thought it was fun! TFL
