For our youngest’s 4th birthday A. wanted monster trucks. We decorated with checkered flags and black/white tablecloths. Laura and Eileen made an amazing monster truck piñata with pull strings (no need to destroy it).
The only catch was that I had “put my back out” a few days earlier and didn’t quite have time for cake awesomeness. But thanks to Pinterest I found an idea for a cake that required no fondant and next to no decorative frosting. The most important items were monster trucks (check!) and smashed cookies! The 4 year old was more than happy to smash chocolate cat cookies and graham crackers. The middle child T. made the chocolate frosting with minimal instructions (and it was awesome!) and all I had to do was shape the cake and frost!
