My son loves construction trucks, so I decided to make him a construction cake. I used butter cream frosting and the Wilton gel coloring to get the proper colors. The dirt pile was extra cake crumbles, the road was crushed graham cracker, the grass was coconut dyed with green food coloring, and the rocks and rock pile were chocolate skittles stuck together with the frosting.
I put a few candy corns around the dirt to look like construction cones, and used pretzel rod pieces cut in half as logs. The toys were a Tonka set from Walmart.
