It's birthday season in our family so we bought a couple of ice cream cakes from DQ. Great service, even helping us to get one decorated on a Friday night when we were in a bind but they didn't have a cake decorator working.
I have no idea what the ingredient list is for the ice cream cake and probably prefer not to know, but I was pleasantly surprised that the substantial packaging that protected the round cakes was all #1 plastic which can easily be recycled locally. The sheet cakes were in cardboard that is also simple to recycle around here. Thanks for not making me throw away 3 pounds of plastic!
