Snickers ® Marathon™, not to be confused with Marathon, the former name for the Snickers chocolate bar in the UK, is a new chocolatey energy bar or candy bar that contains a new trademarked ingredient Quadratein (soy protein isolate, peanut flour, whey protein isolate, calcium caseinate).

The "Chewy Chocolate Peanut" flavor that I got also has a caramel taste, but a peanut taste is harder to detect. The mouth feel of the bar is much like a soft rice krispies treats.
