Three’s definitely company as Burger King tests three new plant-based Impossible burgers at 180 select US locations: the Impossible Whopper Jr., Impossible Burger, and Impossible Cheeseburger.

Much like the chain’s recently introduced Impossible Whopper, the three new Impossible burgers take the chain’s existing namesakes and swap out the beef patties for plant-based Impossible patties.

The new lineup of Impossible burgers can be found at 180 Burger King test locations in Milwaukee, Wisconsin – Cedar Rapids, Iowa – Augusta, Georgia – Cincinnati, Ohio – and Buffalo, New York.

Both the Impossible Burger and the Impossible Cheeseburger are available as part of the brand’s existing King Jr. kids’ meals. The distinction makes Burger King the first national fast-food chain to include plant based menu items on a kids’ menu.

The Impossible Whopper Jr. features a flame-grilled plant-based Impossible patty, topped with tomatoes, fresh lettuce, mayonnaise, ketchup, pickles, and sliced white onions on a soft sesame seed bun.

Meanwhile the Impossible Burger features a flame-grilled Impossible patty made from plants, and comes topped with crinkle cut pickles, yellow mustard, and ketchup on a toasted sesame seed bun. The Impossible Cheeseburger adds a slice of cheese to the build. Both versions are also available a la carte.
