No it is not a cake. A Cake has to have some flour . If you crush cookies on it then it would be a cake but ice cream covered in frosting is not a cake.

Lowerourtuition, not if you have a deep freezer. Ubiquitin, if the recipe changes to slicing in half, placing cookie crumbs, reassembling and then frosting it, that changes it, right?
