King Fusion: A Sundae Series Made for Mixing
King Fusion is a popular sundae series that Burger King® has offered in Japan, known for tasting best when mixed. This newest edition features flakes of KitKat, a chocolate familiar to many in Japan, as its topping.
Highlights
Mellow Soft Serve × Rich Chocolate Sauce
The base is mellow soft serve, paired with a rich, smooth chocolate sauce for a dessert that lets you fully enjoy the flavor of chocolate.
Two Kinds of KitKat Flakes
The KitKat flake topping combines two varieties:
- Toasty sugar wafer flakes
- Sugar wafer flakes coated in gently sweet chocolate
Combining the toasty flakes with the chocolate-coated ones adds contrasting flavors along with a satisfying crunch.
Recommended: Mix It Well
Stirring the soft serve, chocolate sauce and flakes together adds a crunchy texture to the smooth, creamy mouthfeel, making the sundae even more delicious. With its rich chocolate sauce and irresistibly crunchy flakes, it is a must-try for KitKat fans, and a great pick whenever you want a slightly special treat.
