This was a last minute order for a 4 x 4 pick up truck for a little boy's first birthday. I simply stacked and carved down a 1/2 sheet cake into a truck shape and iced accordingly. She wanted whipped frosting, which will be my last time with 3D cakes, it was so hard too smooth. The tires are doughnuts, the plates are fondant, and the 1 is made out of marshmallow sundae topping.
