According to the search results, there is no evidence that Hungry Jack mashed potatoes have been discontinued. They are still widely available in supermarkets and grocery stores across the United States and on Amazon, Walmart, and Basic American Foods. However, there was a limited, voluntary recall of three specific lot codes of Hungry Jack original pancake and waffle mix in the past, which could be one of the reasons why some people may have a hard time finding Hungry Jack mashed potatoes near their location.
