Tobaâs Dark Chocolate cake for skateboard, Vanilla & Sugershackâs buttercream frosting, rolled marbled vanilla BC for skateboard. Skateboard is carved 13x9 and one 10-in. Shoes carved Tobaâs Vanilla 13x9 cake, covered in chocolate rolled BC. Was going to tip one of the shoes on its side and sole would match the skateboard, but cake was bigger than designed and board not large enough! Paper covering board is skate paper. Little boy is 8 and he loved his cake, he just kept staring at it!! First time marbling rolled buttercream. Wouldnât recommend covering such a large cake again, but adore the taste of rolled BC over MMF!
