MIAMI, Sept. 28 (UPI) -- Fast food chain Burger King announced the creation of a Halloween-themed burger featuring "something wicked" -- an all black bun.
The chain announced on Twitter the limited-time "Halloween Whopper" was created by baking the bun with A1 steak sauce.
"Something wicked is coming," the company tweeted.
The chain's Japanese wing previously released black-bun-bearing Kuro Pearl and Kuro Diamond burgers for a limited time around Halloween last year. The Japanese versions of the black bun were made using bamboo charcoal instead of A1 sauce. The burgers also featured the same ingredient added to cheese to give it a similar black hue.
Rival restaurant McDonald's also waded into the black bun burger game last year, but the squid ink-darkened buns created a color closer to dark brown than Burger King's black.
