Butter cream with fondant/gumpaste decorations. Letters all done on the cricut. I actually tried to shape both of these cakes mad hatter style but once iced you could barely tell. I ran into a "buttercream nightmare" while stacking ...and there was no fixing it; so it is missing a 2 x 8 center tier. It also had to ride for an hour on my lap an at the moment I got in the car, it dawned on me that I had forgot the support straws on the bottom layer. There was only one dowl straight through the center and anchored in the cake board. IT MADE IT THOUGH!! YAAAY!! Jess loved it and in the end that is all that counts!
