I made this Mack Truck Birthday Cake out of 2 9×13 cakes, cut the long way, frosted and stacked on top of each other. The front cab was made from a loaf pan. I cut one third off and put it on top. 3 boxed cake mixes total.
I used the scraps from the long cakes to hold the trailer up, Oreos for wheels and 2 Oreo straws for the smoke stacks. I used a star tip for most of the cab and drew windows, doors, the grill, headlights, and license plate with a #2 tip. I recommend doing a license plate to write something cute and unique.
Thanks for looking hope you liked it.
