With the vast proliferation of hyper-caffeinated foods and beverages over recent years and the popularity of Starbucks and other coffee shops, I'm surprised by the lack of coffee infused chocolates on the US market. There are plenty of coffee flavored chocolates or the occasional chocolate covered espresso bean but there's nothing quite like Ferrero's Pocket Coffee which contains a mini shot of espresso liqueur in a thin sugar shell coated with chocolate.
As can be expected from European foods, even candies and confections, the flavor is rich but not overly sweet, relying on fat and moderate sugar rather than bucket loads of corn syrup and lacking any hint of artificiality. I tried to gauge the effect of the caffeine content but it was not noticeable. I read that three pieces is equivalent to a shot of espresso so it's clearly not intended to be a stimulant.
A definite treat for any coffee fiend but good luck finding the stuff and don't expect the same buzz you'd get from caffeine infused "energy" foods.
