chocolate cake, BC icing. Car is a rice krispie treat carved by my wonderful husband. Iced also in BC. If I were going to do it again I would do the car in Royal icing. THis was such a headache, my biggest challange so far. I was determined to make it special, this little boy is a new big brother and having a hard time adjusting to not being the baby anymore( after 8 years). thanks for looking!!!!
