Where the Frosty came from

Introduced 1969

Dave Thomas put the Frosty on Wendy's menu in 1969 as one of the original five items, and made it thick enough to require a spoon — inspired by milkshakes he had grown up with in Detroit. The original recipe came from Fred Kappus.

The original "light chocolate" flavour was a blend of chocolate and vanilla rather than pure chocolate. Thomas believed a full chocolate flavour would overwhelm the taste of the hamburgers it was sold alongside.
A dedicated vanilla Frosty did not arrive until August 2006, after repeated customer requests.

Is the chocolate or vanilla Frosty lower in calories?

Why is a Frosty so thick?

By design. Dave Thomas wanted it thick enough to need a spoon, and blended chocolate with vanilla so the flavour would not overpower the burgers.
