This is the easy way i.e. &quot;lazy&quot; way to make a monster truck themed birthday cake. My 4th son is a monster truck FANactic! Well unfortunately for him and me, his bday always seems to come around the worst of the pollen season and the height of my asthma flare ups. I was just not feeling up to to snuff enough to bake and decorate the whole cake thing, so I came up with this easy solution.
