My son loves tractors and construction trucks, so I did a little of both for his birthday. I made a construction birthday cake from a 11*13 white cake with a fresh strawberry buttercream inside. Finished it with a neoclassic buttercream.
I used crushed Nilla wafers for the road and border and pile of dirt. I then used chocolate raisinets and yogurt raisinets for the different rocks. I was going to do spun sugar for the hay pile, but ran out of time.
This was simple to do and he loved it!
