My nephew wanted a dirt bike cake for his 4th birthday, when he races (goes around in circles) his dirt bike at the end they all go over the tire mountain that the big kids race over. That is what this cake is, the tire mountain. He loved it. Butter recipe and devils food cake with cream cheese icing and crumpled up Oreo cookies for the dirt. Props are remote control dirt bike and Tonka 4-wheeler. Thanks for looking.
