Here in the U.S., we pretty much only get the plain regular Kit Kat bar with some very slight variations (dark chocolate, white chocolate), but the world is vast, so I thought it'd be interesting to look at
what Nestle has done with Kit Kats worldwide (in the U.S., Hershey's produces Kit Kats, but for the rest of the world, it's made by Nestle, which might explain our lack of variety here).
In several countries, there's
Kit Kat Ice Cream with bite-sized balls of Kit Kat embedded in it, but that's not all...
There's also the
Kit Kat Cone which is literally a sundae cone where they stick a Kit Kat into the middle:
It does not exactly scream "effort," and I imagine you'd have a better time of it just grabbing a Kit Kat and putting it in yourself, so that it's not frozen solid.
But if you don't feel like doing it yourself and don't want a frozen Kit Kat, in Spain, McDonald's offers a Kit Kat Cone as well (there's also a Kit Kat McFlurry in some countries):
If ice cream isn't your thing,
Kit Kat Bites with yogurt for dipping are also available in Spain:
If you think baking a Kit Kat is a good thing,
Pizza Hut Middle East starting selling
Kit Kat Pops, Kit Kats baked inside of pizza dough, earlier this summer:
Of course, for maximum Kit Kat variety, there's no beating Japan, which currently has over 50 varieties of Kit Kats, many of them as limited-time flavors, and 27 of them are region specific; even if you live in Japan, you can't get them unless you travel or have them shipped from their respective regions. People actually bring them back as souvenirs when they travel to different areas of Japan!
I'm not going to list them all, but here are some examples:
In June, Nestle Japan introduced the limited-time Vanilla Ice Cream flavored Kit Kat:
I actually saw these at a Japanese supermarket here in the U.S. but it was pricey: $5.99 for a bag of 13 mini Kit Kat bars and they're actually more expensive in Japan at 500 yen (~6.35 U.S.).
On the "I'm not sure I'd want to eat this at all" side of things, there's wasabi (horseradish) flavored Kit Kats:
They're only available in the Shizuoka and Kanto regions.
Then, there's Ogura Toast Kit Kats:
Ogura is a sweet red bean paste and it's spread on toast like we would peanut butter or jam. These are only available in the Tokai and Hokuriku area where you'd find the city of Nagoya.
Finally, for something more decorative, there's Kobe Pudding Kit Kats (from the Kobe region obviously).
Kobe is a city that features western-style houses so the box reflects that, and Kobe Pudding is one of its popular foods (although it is probably better known for Kobe beef). It looks a lot like flan, but with the addition of citrus liquor for a refreshing citrus note.
