Also known as “Wacky Cake,” “Depression Cake,” or “Crazy Cake,” this legendary one-bowl dessert rose to fame during the Great Depression when butter, eggs, and milk were scarce. Yet despite its humble origins, it’s incredibly moist, richly chocolatey, and ready in just 15 minutes of prep—no mixer, no fancy ingredients, and no dairy or eggs required.
It’s not magic—it’s clever baking science. And yes, it really works.
