This is 4 9in square cakes cut in half and set sideways next to each other. It is yellow cake and buttercream icing. It is my first try at a frozen buttercream transfer. It was for my husband's birthday and all his co-workers loved it. I used buttercream icing in between each layer to glue them together. The bottle neck was just pieced together with scraps. It's not perfect but I was very proud.
