Cookie cakes? And I thought that sandwich cake was weird. It's cake with layers of bread and meat and things that are usually in sandwich. Instead of frosting it is covered in mayo or melted cheese but never in anything sweet. My wife and her family make them. I think those cakes are an abomination.
So, basically a giant sandwich? Or perhaps a pizza with bread both on top and on the bottom? That sounds pretty good, actually.
Reminds me of something my mum made me for my birthday, one year: a pizza burger. Basically, you make two pizzas, cook up a burger patty
the size of a pizza, cover said patty in bacon, put it on one of the pizzas and flip the other over on top of it. IT WAS AWESOME.
