"The legendary 1966 contest winner that made the Bundt pan famous."

The Story
Created by Ella Helfrich for the 17th Pillsbury Bake-Off, this recipe took 2nd place but became a national sensation. It is credited with single-handedly saving the Nordic Ware company by creating a massive demand for Bundt pans across America. The original version relied on the specific formulation of a now-discontinued frosting mix, leading Pillsbury to adapt the recipe for their flour bags.
