Which fast-food chain created the Blizzard dessert, first sold in 1985?

Dairy Queen created the Blizzard dessert, first sold in 1985.

The Blizzard is a soft-serve-based dessert blended with pieces of cookies, candy, or other ingredients. Its thick consistency became part of the product's identity, and Dairy Queen restaurants famously serve it upside down in promotional presentations when the mixture is sufficiently firm.

The dessert quickly became one of Dairy Queen's signature products and inspired many flavor variations. Its format differs from a conventional milkshake because the mix-ins are blended throughout the soft serve rather than simply added as a syrup or topping.

The Blizzard's 1985 launch is distinct from Dairy Queen's earlier history. The company began in 1940, while the Blizzard became a later menu innovation.
