Yes, Burger King has a special sauce called stacker sauce. It is a famous sauce among their customers because of its unique and delicious taste.

Has Burger King Discontinued The BK Stacker?

Has Burger King Discontinued The BK Stacker

The BK stacker returned in January 2023 on Burger King’s menu. In 2012, BK discontinued the BK stacker, but now this iconic burger has made its way to the official menu.

The reason behind the discontinuation of the BK stacker is believed to be due to low sales or a change in the company’s marketing strategy. With stacker, Burger King also discontinued many other items on their menu. 

The BK stacker was officially off the menu but remained a popular item among Burger King’s secret menu offerings. People were still ordering it by customizing their orders.

The good news is that the BK stacker has returned, and it’s exciting news for everyone. Burger King has reintroduced the triple and quad stacker burgers with their flame-grilled beef patties, melted American cheese, crispy bacon, and the iconic stacker sauce. 

The BK Stacker Burgers Review

The BK Stacker Burgers Review

What makes the BK stackers stand out is their unique preparation method. The patties are flame-grilled, giving them a smoky, charred flavor that’s hard to resist. And because they’re stacked, each bite is packed with savory, juicy goodness.

Another thing that makes the BK stackers so appealing is their simplicity. You won’t find fancy toppings or sauces on these burgers – just the classic ingredients that work together perfectly. The bacon adds a salty crunch, the cheese provides a gooey richness, and the patties are the show’s star.

Burger King’s signature flame-grilled flavor is evident, and the burgers taste as if they’ve come straight off the grill. The cheese slices are stacked between beef patties, giving you gooey goodness in every bite.

Several food blogs and YouTubers have also reviewed the burger and shared their thoughts, which I will share here.

According to the Brand Eating,” The burger looks pretty normal-sized in the photos, but it, like the rest of the King line, is the same width as a whopper.” They added, “Stacker sauce tastes like a mayo-based sweet relish sauce, which is to say it’s fairly sweet and somewhat tangy.”

The other famous food site, Pen Live website reviewed,” The bacon was limp, not crispy, and the sesame bun was only slightly toasted. The Stacker sauce offered a sweet hint to the entire package. It resembles a thousand island dressing. Truthfully, I prefer simple ketchup and mustard, maybe some onions.”

Overall, the BK stacker burger is a cheesy, meaty delight that will satiate your cravings.

According to a famous Youtube channel Peep This Out, “This stacker is pretty much like a king Burger because it’s a half pound of beef two of the whopper-sized patties, but it’s split down into four, so it sounds like a lot, and it is because it’s very dense, but it’s small enough to feel like you’re getting a lot of beef for the money with this one guy considering the price point.”

The BK stacker burger is certainly flavorful but also quite greasy and heavy, making it a bit overwhelming to eat. So, if you are a fan of hearty burgers, this stacker will give you a taste attack. 


The BK stacker burgers are a hearty and flavorful addition to Burger King’s menu. With four variants to choose from, there’s something for everyone to enjoy. Despite being discontinued in the past, it’s set to make a comeback, and it’s been a part of the secret menu.
