Clubwoman's Cake

Clubwoman’s Cake, also known as wacky cake or crazy cake in other parts of the country, was born during the Great Depression when eggs, butter, and milk were scarce and expensive. Resourceful home cooks figured out that vinegar and baking soda could mimic the leavening action of eggs, and vegetable oil could stand in for butter. The result is a moist, tender chocolate cake that somehow tastes richer than cakes loaded with dairy.

The vinegar-and-baking-soda reaction is the science that makes this cake rise. As soon as the acidic vinegar meets the alkaline baking soda, carbon dioxide bubbles form and aerate the batter. You have to bake the cake promptly, since the lift disappears as the gas dissipates.

The mix-in-the-pan method is the other charming detail. No mixing bowl, no electric mixer, just a fork and a cake pan. Some old recipes even have you make three wells in the dry ingredients (oil in one, vinegar in another, vanilla in the third) before pouring the water over everything and stirring. It is a cooking-with-kids gold mine for that reason.

Cocoa powder is the entire chocolate component, so use the best you can afford. Dutch-process gives a deeper, darker flavor; natural cocoa gives a brighter chocolate tang. Either works beautifully.

Pro Tips

• Use room-temperature water for the best bake; cold water from the tap slows the reaction and can give you a denser cake
• Grease the pan well or line with parchment paper; the low-fat batter tends to stick on its own
• Test doneness with a toothpick in the center; it should come out with a few moist crumbs, not wet batter
• This cake stays moist for three days covered at room temperature; it is a great make-ahead bake sale or potluck cake

Variations

• Bake in a loaf pan or 9×13 sheet pan instead of layers; adjust cook time accordingly (loaf needs 45 to 55 minutes)
• Add a teaspoon of instant espresso powder for deeper chocolate flavor without any coffee taste
• Frost with a chocolate ganache or simple buttercream, or keep it simple with just a dusting of powdered sugar
