Chocolate

Caffeine is found naturally in cocoa beans, so any chocolate has a little bit of the stimulant. Candy bars generally have less than 10 milligrams, but the darker the chocolate, the higher the caffeine content. Hershey’s Special Dark Chocolate Bar has a whopping 31 milligrams, almost as much as a can of Coke! Some chocolate is fortified with additional caffeine for an energy boost—take the limited edition Snickers Charge, which has 60 milligrams of caffeine, about the same as a cup of tea.
