I'm making a Very Hungry Caterpillar cake (similar to the one below) for a friend's baby's 1st birthday this weekend. I have to put the cake together on Friday night, deliver Saturday morning and the party is Sunday afternoon. She wants white buttercream, not fondant on the cake. I'd like to use something like candy fruit sours or gumballs for the balls around the bases of the cakes, but I'm not sure if the color would bleed onto the buttercream? What do you think?
