For the coming Halloween season, Nestle Japan has introduced Caramel Pudding KitKat. Halloween is not a big holiday in Japan. In fact, it is mostly celebrated by children and usually only in a school (for example, English school). When Halloween rolls around, you rarely see people in costumes. That being said, you may see some adults in costumes if their regular watering hole has a party.
Caramel Pudding KitKat is made from caramel pudding flavored chocolate with some caramel powder in the cookie wafers. The flavor is very creamy and the more you crunch up the cookie, the stronger the caramel flavor becomes. It is quite sweet.
If you are a fan of caramel, or having a Halloween party, then I would suggest giving these a try. Each individual package has a small message on it. I saw about 5 unique messages in the pack I bought but I am not sure how many there are in total. It just adds to the fun!
