Snickers came away with the victory, proving that those folks know what the hell they're doing over at Mars. It won out because its intermingling textures -- crunchy, velvety, and flaky -- were of a high enough quality at room temperature that they became something even better when frozen (just like Idina Menzel).
As for the other two that broke into the top three? You've got some solid (!!) Summertime options with Almond Joy and Butterfinger. Sure, there are already Butterfinger ice cream bars on the market, but we recommend you go DIY and throw a candy bar in the freezer. You might be surprised at the outcome.
