Burger King may be considering bringing a spooky burger to the U.S. in time for Halloween.

According to the blog Burger Lad, the fast-food chain will be selling, for a limited time, a burger with black buns in the U.S. The "HA.1.OWEEN WHOPPER" will put a traditional Whopper plus A.1. steak sauce between two black buns as a Halloween promotion.

Other autumnal limited time offerings that will reportedly join the menu with the spooky burger are the A.1. Smoky Bacon Tendercrisp and a Pumpkin Spice Oreo Shake.

A Burger King spokesperson told Entrepreneur that the company could not confirm plans to put a burger with black buns on the menu.

While this would be the first time Burger King brings a burger with black buns to the U.S., the fast-food chain has previously successfully sold a similar burger in Asia. Burger King and McDonald's both released their first burgers with black buns in Japan and China in 2012, and last year Burger King's " Kuro (Black) Burger" had not only black buns, but also black cheese, darkened with charcoal -- a gross extra step that the Halloween burger doesn't seem likely to copy.
