...or "Candy Ice Cream Bars" as some might call them. The genius who first came up with this idea is probably swimming in his own pool of money a la Scrooge McDuck. Or maybe she ate too many of her own creation and died from Type II diabetes.
In either case, the world is a better place because of the elimination of any dichotomy between "ice cream" and "candy bar."
Note: Not that we either had to really choose between the two treats as evidenced by the popularity of candy bar toppings.
Although most of the major candy companies have come up with ice cream versions of their most popular bars or candies, still absent is a sufficient ice cream edition of the M&M. Yes, I know Mars has put out an M&M cookie ice cream sandwich; however, this novelty fails to replicate the true M&M consumption experience. Specifically, what I'm suggesting is that Mars issue slightly larger M&Ms filled with milk chocolate ice cream (or peanut butter ice cream or mint ice cream to represent different M&M flavors) and sell them by the bag in the freezer section.
I think the contrast between the hard candy shell and the soft ice cream would be divine.
