It's a Truck, It's a Cake, It's a Remote Control Truck Cake
I have no idea how this cake was made, but it's pretty awesome. If I was a kid, I would definitely want this.
For the record, this wasn't the only one. I found several other remote control car or truck cakes on YouTube. (I'm not sure I would want to eat the cake after all that rolling around, but they do look interesting and clever).
