Chocolate Wacky Cake:

  • cooking spray
  • cups all-purpose flour
  • 1 cup sugar
  • ¼ cup cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 6 tablespoons vegetable oil
  • 1 tablespoon white vinegar
  • 1 teaspoon vanilla extract
  • 1 cup cold water


Chocolate Wacky Cake:

  • Preheat the oven to 350 °F.
  • Spray a 9-inch round cake pan lightly with cooking spray.

  • Add the vegetable oil, vinegar, vanilla extract, and water. Stir until smooth.
  • Pour the batter into the prepared pan.
  • Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs (no wet batter).
  • Remove the cake from the oven; cool completely in the pan on a wire rack.
  • Enjoy as is, sprinkle with powdered sugar, frost with your favorite frosting, or top with a dollop of whipped cream.

Vanilla Wacky Cake:

Recipe Notes

  • The white vinegar can be replaced with lemon juice. 
  • You can use a 8 x 8-inch or 9 x 9-inch square pan instead of a round pan.
  • You can double the recipe and use two 9-inch round pans or a 9 x 13-inch pan. Baking time will be the same.
  • For a delicious mocha version of the chocolate wacky cake, replace the water with 1 cup cold coffee.
