I made this cake for my son's eleventh birthday, which he happens to share with an older family member who joined us for cake on the spur of the moment (hence the 'and Ellen'). My son loves all things muddy and off-road! I used a regular chocolate cake mix and chocolate frosting from a tub. I put a candy bar on top and buried it in frosting, then crushed Oreo cookies to make the road. The four-wheeler is a toy from the dollar store.
