Taco Bell has slathered a flour tortilla with melted chocolate and stuffed it with Kit Kat and Twix pieces in a new experiment that's being tested at select restaurants in the U.S.

Spotted by Brandingeating.com, the Kit Kat Chocoladilla is being sold at select restaurants in Wisconsin, along with a new vanilla iced coffee, both of which are priced at $1.

The dessert quesadilla makes its U.S. debut, after launching first in the UK last year, where it went by the name Chocodilla.

Customers can choose between Kit Kat and Twix candy bar pieces where available.

It's the latest fast-food mashup with popular junk food brands.

Taco Bell's Locos Tacos turn Doritos nacho cheese chips into savory taco shells, while Burger King coated sticks of macaroni and cheese and chicken fingers in Cheetos dust and threw them in the deep fryer.
