Whatchamacallit has quite the origin story! This iconic candy bar started with a simple peanut crisp core wrapped in chocolate, but got a major upgrade in 1987 when caramel joined the party. That's the delicious combo you'll find in every bar today. Though its heyday of advertising glory was back in the '80s, this treat has kept a devoted fan base through the decades. A fun fact: around 2008, the recipe tweaked its chocolate classification, but the magic that makes it so craveable stayed exactly the same.
