40 minIf you’ve been to a potluck anywhere south of the Mason-Dixon line, you’ve had this cake. Thin, chocolatey, and iced while it’s still screaming hot so the frosting melts right into the crumb.
The batter starts on the stovetop where margarine, oil, water, and cocoa get boiled together, then poured over the dry ingredients. Buttermilk and baking soda give it that tender lift.
Pour the whole thing onto an ungreased cookie sheet, bake for 20 minutes, and frost it the second it comes out of the oven with a rich cocoa and powdered sugar icing loaded with nuts.
It feeds a crowd, travels well, and disappears fast. What more could you ask?
Kitchen Tips
- Frost the cake immediately out of the oven so the icing soaks into the top layer and creates that signature fudgy crust
- No need to grease the cookie sheet. The cake has enough fat in the batter to release easily
- Buttermilk is key for tenderness. In a pinch, stir a teaspoon of vinegar into regular milk and let it sit 5 minutes
