What is the name of the popular soft-serve treat at Dairy Queen?

The popular soft-serve treat at Dairy Queen is the Blizzard.

A Blizzard combines Dairy Queen's soft serve with mix-ins such as cookie pieces, brownies, candy, fruit, or sundae toppings. The ingredients are mechanically blended through the soft serve, producing a thick dessert that can be served upside down as a signature demonstration.

Dairy Queen introduced the modern Blizzard in 1985, and the product quickly became one of the chain's defining menu items. The company sold more than 100 million Blizzards during its first year. Its name reflects the dessert's cold, thick texture and the blizzard-like appearance created by mixing in the toppings.

The Blizzard is often confused with a milkshake, Frosty, or McFlurry, but its texture and preparation are different. Dairy Queen's soft serve is also not officially labeled “ice cream” in the United States because it contains about 5% butterfat, below the FDA's 10% minimum for ice cream.
