I have been looking for some for over a year so I would love to know the answer to that as well--I know that a company called LeCarb was coming out with a "frozen desert" but I haven't seen it in the stores yet--since they did not refer to it as an "ice cream" but a "frozen desert" I'm hoping that it may be more like a shrebert. Sorry I'm not much help. :no
Here's a link--I'm wondering about the lemon and strawberry flavors
