I LOVE Puffcorn! And this recipe is great 'cuz it's a crunchy caramel not gooey and super sticky.
To make it like Boy Scout carmel corn with chocolate, cover the carmel corn in chocolate coating
Even just covering in white chocolate without the carmel is good. At Halloween and Christmas, we call it Ghost Poop or Snowman Poop and do it up in baggies for potluck treats.
