The available varieties are: the Deluxe, Mushroom & Swiss, and Western BBQ and each BK Topper comes at a suggested retail of $1.99.
The burgers also feature a noticeably thicker 3.2-ounce patty compared to the 2-ounce patty on Burger King's regular Cheeseburger.
The Deluxe's toppings include American cheese, lettuce, onions, pickles, and Stacker sauce.
The Mushroom & Swiss comes with mushrooms, Swiss cheese, and Griller sauce.
The Western BBQ features onion rings, American cheese, and Sweet Baby Ray's Spicy BBQ sauce.
You can expect these to be available until the end of the year.
Looking at the ingredients, BK's Griller sauce seems to be a garlic mayo variant whereas Stacker sauce is a take on Thousand Island (aka "secret sauce").
