Here is a response I got today. I have replied for more clarification, as it sounds like all the ice cream is the same. Will post back my reply.
Hello - We do have an allergen control program at our ice cream
Hood Ice Cream Sandwiches do NOT contain any peanut or tree nut
and our Hoodsie Cups are peanut-free.
However, our vanilla ice cream is run on the same lines as the nut
containing products. I hope this is helpful to you and let us know if
have any other questions.
