A 10" round cake base with 4" stacked cakes for the shuttle and krispie treat "jet packs". The cake was triple chocolate fudge with oreo filling - a popular combination this week. All icing in buttercream. I was really worried the shuttle would fall so I triple doweled it and "glued" the heck out of it with the buttercream flames. The shuttle made it to the party and was even removed and taken home.
