After her husband Harvey died in 1944, Inez Warninger gave the cake to Ronald's parents around 1960, "because they had a better freezer," he told BuzzFeed Life.
"I knew it dated way back into the teens, and that I wasn't allowed to touch it, but that’s all I really knew," he added.
Warninger brought the cake to his home in the early 2000s, and by that time, "it had already been petrified." He knew the cake was important, but he promptly forgot where he put it. He was organizing his Yakima, Washington, garage in November when he uncovered the antique dessert on a shelf, perfectly preserved inside a hatbox.
