I have been dying to do a Phineas and Ferb cake for a while since it is one of my daughter's favorite shows. My friend's son wanted a P&F cake, so she let me run wild! The cake is devil's food with twinkie filling and buttercream. Fondant accents, and the characters are tinted candy melts piped onto wax paper like a transfer. I put sucker sticks on the characters so the kids at the party could each have their own. It was time consuming, but I was pleased with how it turned out, even if the humidity caused my buttercream to be tempermental and not cooperate.
