Oh the things we do for our children....... So after a trip to Monster Jam, our son wanted a Grave Digger for his birthday. Not to mention that we got to see this one up close and personal and got to meet the driver. I'm sure that had something to do with it. So this is a 9x13 sheet with chocolate marble cake and chocolate buttercream. The truck is carved from poundcake, covered with chocolate buttercream and covered with fondant. The tires are rice krispie treats. All of the icing on the truck is royal. There are a few things I would do different next time but when the birthday boy comes in with a huge smile and says thats the best cake ever and thank you, it just makes your heart melt and you know you would do it all over in a heartbeat.
