Giant castle cake
This was a wedding cake for 900 guests. 4' wide x 3' deep x 4' tall. The turrets on the corners are cut from plywood and iced with royal icing. Two layers are hatboxes iced in royal icing with pink velum paper over the windows and battery operated white xmas lights on the inside. The edible part is 12-9x13 layers, 3-10" round layers, 8-8" round layers, and 2-6" rounds. My #1 comment once it was set up and in place: "Never EVER Again!" (Now, 4 years later it doesn't seem as bad).
