Crowned as the top performing LTO item of 2017, Stackers returned for the second year running!

Its interactiveness and customisability greatly appealed to BK fans and new consumers alike, allowing them free rein to add as many layers of flame-grilled meat patties and cheese slices to their burgers as they wish.

Besides serving to remind fans about the superior quality of BK meat patties, the offering also saw a surge in organic engagement as fans created food challenges as well as shareability amongst themselves.
