Taco Bell is partnering with a global food company to create another concoction: Kit Kat Chocoladilla.

It's a flour tortilla with bits of Nestlé's Kit Kat melted inside. The Chocoladilla sells for $1 and the dessert quesadilla is being tested in Wisconsin.

The mash-up follows the Kentucky-based chain's successful collaboration with Frito-Lay. The Doritos Locos Taco started out as a test item. Demand for the taco led to it becoming a regular item on the menu.
