Ingredients:
- 3 cups all-purpose flour
- 2 cups white sugar
- 8 tablespoons unsweetened cocoa powder
- 2 teaspoons baking soda
- 1 teaspoon salt
- 1/2 cup olive oil
- 2 tablespoons cider vinegar
- 2 teaspoons vanilla extract
- 2 cups water
Mix flour, sugar, cocoa powder, baking soda, and salt together in an 9x13-inch ungreased pan. Make 3 depressions in flour mixture; pour oil into one, vinegar into second, and vanilla into third. Pour water over all, then whisk until well blended and resembling cake batter.
Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 30 to 40 minutes.
You can top the cake with powdered sugar, whipped cream, or your favorite chocolate frosting.
