This construction site birthday cake is made on a full sheet cake. The "dirt piles" are mini wonder mold cake mounds iced in bc and covered with vanilla wafer crumbs for sand and oreo cookie crumbs for top soil. Toy trucks carry pirouette cookie "logs", dump trucks and front loaders dig up top soil. Miniature plastic pine trees and jelly bean rocks add to the decorations. Small construction signs decorate the border of the board. Airbrush was used to apply a subtle green base to the ground.
