My grandson wants a police car cake and since I've never done cakes before I am not sure how to do this. I have a cake mold for a car and thought I would fill it with rkt to form the car instead of cake. My daughter ordered a cake from Costco and I was wondering if I can put the completed rkt police car on top of the buttercream or will I have a disaster? Will it sink into the cake?
