This humble little cake goes by many names—Depression Cake, Wacky Cake, or Crazy Cake—but no matter what you call it, it’s pure chocolate comfort. Born out of the Great Depression when butter, eggs, and milk were scarce, this cake is proof that simple pantry staples can still create something rich, moist, and irresistible.

My kids love it for its fudgy flavor, and I love it because it takes less than 10 minutes to mix. No fancy equipment, no long list of ingredients—just one bowl, one pan, and a whole lot of nostalgia.
