USTOP had these limited edition snickers. The Xtreme is all nuts and caramel covered in chocolate. It is nice that it is still a full height bar unlike the Milky way caramel which was thinner than a normal Milky way. The caramel is just soft enough and delicious.
The peanut butter one comes in two squares and it seems there is a layer of nougat on the bottom, a slab of peanut butter, caramel, and finally chocolate. Reminded me of a PB twix.
