The limited period launch next week follows a pilot test run carried out last year.
The new combination includes KFC’s flagship fried chicken along with a warm, fresh-glazed doughnut.
Customers can purchase the combination in a variety of options, including Kentucky Fried Chicken & Donuts Basket meal and Kentucky Fried Chicken & Donuts Sandwich.
Customers can also add a doughnut to any meal for an additional cost.
The US fast-food restaurant chain added that the combination will be available until 16 March or until supplies last.
KFC US chief marketing officer Andrea Zahumensky said: “Chicken & Donuts is the newest fried chicken trend we’re bringing to all of America.
“But not just any doughnut would do. Only a doughnut that’s glazed-to-order and served piping hot every single time can stand next to our hand-breaded fried chicken. It’s a finger-lickin’ good dish filled with glaze and glory.”
Along with the launch, the company will also open a pop-up shop in Los Angeles for a day to promote its Kentucky Fried Chicken & Donuts pair.
KFC currently has more than 23,000 restaurants across 140 countries and territories.
In November last year, KFC opened its first ‘Drive Thru Only’ restaurant in Newcastle, Australia.
