My son wanted a Batman Monster Truck birthday party. I copied the cake idea from another individual. I bought a Wilton car pan and cut the back half of the car out to make it resemble a truck. I used gumpaste for the wings and Rice Krispie treats wrapped with fondant for the wheels. Several toothpicks hold the wheels to the cake. I cut out the Batman signal out of yellow and black fondant. The "truck" is supported by 4 plastic columns. I made the mistake of leaving them white not wrapping them with black fondant. The bottom part of the cake is a sheet cake trying to look like a road.
For the treat bags, I cut out the Bat signal out of the foam sheets and attached them to yellow and black paper bags. When making the Bat signal I suggest tracing it on the side you plan to attach to the bags. The pencil marks will show and the pencil does not erase cleanly. I got the invitations off of Ebay that look like tickets to a Monster Jam event and the picture on the top was of the Batman Monster Truck.
