Taste: This version of Butterfinger included two bars, in the same end-to-end arrangement as the regular King Size package, but these bars were loaded up with extra caffeine. Though the bar was generally similar to the regular Butterfinger, it didn't seem as crispety or as crunchety as the regular bar, as it had a softer crunch. I'm not a coffee drinker, so I figured I would be pretty sensitive to the caffeine, but I didn't notice much of anything as far as getting a big kick from all the caffeine that they supposedly packed into this bar.
"crispety, crunchety, peanut-buttery bar with caffeine!" ... "with as much caffeine as the leading energy drink" ... "Not recommended for pregnant women, children or persons sensitive to caffeine"
