Made this for an 8-year-old boy's birthday. 10x13" marble (chocolate and green) bottom with a loaf pan for the top. Mom wanted all covered in buttercream, which was a real pain since it is 101* degrees out today in Las Vegas :) Ground is oreo crumbs, brown sugar and Heath bar crumbs, wheels are Reeses Peanut Butter cups and Hershey bar. Cannon is oreo cookie straw.
