Cake Better Ice Cream
There is only one place I know of with it and thats Marble slab Creamery. They havnt exactly made their way downtown yet but you will find a few out in the burbs. They sell birthday cake ice cream in cartons. It is pretty much the same as cake batter and some consider it better. I'm not exactly sure where you got your info from, but I doubt Ben and jerry scoop shop on queen west is closed yet. I never knew they had cake batter and I might have to check that out.
