Burger King’s new item this time is the Black Truffle Cheese Burger, released on October 14, 2026. Every fall the Truffle Mushroom Whopper season comes back. Burger King seems to have acquired a taste for it, since it keeps rolling out truffle items. This one reportedly goes all in. It has a jet-black truffle bun that evokes black truffles, plus truffle cheese and truffle sauce. It’s a premium burger topped off with a flame-grilled Whopper patty, grilled mushrooms and a soft-boiled egg. It costs 10,700 won for the burger alone in store. It’s so serious about truffle aroma that Burger King itself officially calls it a “black Truffle Mushroom Whopper.” So what is it actually like? Let’s find out.

Black Truffle Cheese Burger: Price and Highlights

Burger King says it ran research and found that the Truffle Mushroom Whopper’s success came down to its rich truffle aroma and premium feel. So this new item maximizes the truffle scent and adds a more upscale touch. Maybe that’s why it feels a bit like a mash-up of Burger King’s Originals and the Truffle Mushroom Whopper, right? Ha. Let’s check the prices first.

Black Truffle Cheese Burger, in-store price: burger only 10,700 won, set 12,900 won
Black Truffle Cheese Burger, delivery price: burger only 11,700 won, set 14,400 won

At just over 10,000 won for the burger alone, it sits in the premium range even among Burger King’s menu. Truffle goes into three places (the bun, the cheese and the sauce), and a soft-boiled egg and grilled mushrooms are added on top. That makes it seem like a price worth splurging on once. The burger alone is 769 kcal, which is as hearty as a Whopper.

Note that the Black Truffle Cheese Burger is a limited-time item sold only until January 5, 2027. Some stores don’t sell it, so check availability in the Burger King app before you visit. New-item coupons show up in the app from time to time, so check your coupon box before ordering too. Ha. Basic members get a 6% discount coupon that can be used in store.

Highlighting the texture of the grilled mushrooms

What’s Inside the Burger

I ordered the basic set for now, so let’s take a quick look at what’s inside. The first thing that catches your eye when you open the packaging is, of course, the jet-black bun. It’s a dark bun reminiscent of black truffle, sprinkled with what looks like an oatmeal grain topping. It feels premium from the very first look.

Because it uses a Whopper patty, it feels hefty in the hand. A yellow soft-boiled egg and cream-colored truffle sauce peek out between the buns. That already had me looking forward to it. The thickness seems about the same as the existing Truffle Mushroom Whopper.

Comparing the burger's ingredient combinations

From the side, the Whopper patty, soft-boiled egg and cheese stand out first. A bit of truffle sauce is peeking out too. Ha. The Whopper patty at the center still shows Burger King’s signature flame-grill marks. White truffle cheese covers it as if melting over it. The cheese spreads generously to the edge of the patty, so it looked like every bite would come with cheese.

A Look at the Cross-Section

Now let’s cut it in half and check the cross-section. On the bottom bun sit the flame-grilled Whopper patty and truffle cheese. Piled on top are the soft-boiled egg, grilled mushrooms, onion and truffle sauce. The yolk is the same soft-boiled style familiar from the Originals. Large pieces of brown grilled mushroom sit on top, so the mushrooms make a clear impression.

At the very top is onion, which supplies a crisp texture among the rich ingredients. The truffle sauce is the creamy type that coats the mushrooms and onion. Overall, truffle aroma is layered on again and again around a flame-grilled Whopper patty, through the truffle bun, cheese and sauce. The soft-boiled egg and grilled mushrooms add more flavor. It’s a burger made squarely for truffle fans.

Showing anticipation for the truffle burger

Taste Test: Savory, Deep Truffle Flavor

Now let’s dig in. Even the bun gives off a faint truffle aroma, so the scent was overwhelming before I’d even taken a bite. Add the yolk of the soft-boiled egg and the thick truffle sauce, and I can hardly wait. Ha.

Highlighting the flavor of the grilled mushrooms

The first bite brings the rich flavor of the truffle sauce and cheese. Smoky char from the grilled patty follows. The truffle aroma is strong, but it comes across as savory and deep rather than greasy. It went down more easily than I expected.

Texture-wise, the soft bun, juicy patty and chewy mushrooms are joined by crisp onion. It never got monotonous. There’s plenty of sauce too. With the crisp onion and chewy mushrooms added, the Truffle Mushroom Whopper character definitely comes through. That said, the soft-boiled egg and sauce are generous and tend to drip. I recommend holding the wrapper firmly.

Summary of the truffle burger's strengths

When the yolk of the soft-boiled egg breaks, it coats the patty and mushrooms like a sauce. That makes the overall taste much smoother and the savory notes richer. The grilled mushrooms were chewy and deeply savory, and they paired really well with the truffle aroma. Overall, it was a very satisfying menu.

About halfway through, there was a moment when the truffle, cheese and yolk piled up and felt a little heavy. A sip of cola to reset my mouth let me enjoy it again like it was the first bite. Ha.

Final Verdict: A Premium Burger Serious About Truffle Aroma

Personally, the truffle aroma is very strong. I think opinions will split even more clearly than with the Truffle Mushroom Whopper. The price is on the high side. I think it’s a perfect fit for people who want to truly experience Burger King’s Truffle Mushroom Whopper line. I recommend it to truffle lovers and fans of burgers topped with a soft-boiled egg. It’s also a good pick for anyone who wants to treat themselves to a burger on a special day. If you’re visiting Korea before it leaves the menu on January 5, 2027, it’s an easy limited-time treat to try. Some stores don’t carry it, so check the app first.
