Time: 1 hour

1 1/2 cups bleached all-purpose flour
1 cup plus 2 tablespoons sugar
1/3 cup natural, not Dutch-processed, cocoa
1/2 teaspoon baking soda
1/2 teaspoon salt
1/3 cup vegetable oil
1 teaspoon vinegar
2 teaspoons pure vanilla extract
1 cup cold water or coffee.

1. Heat the oven to 350 degrees.

2. In an 8-inch x 8-inch x 2-inch nonstick pan, stir together flour, sugar, cocoa, baking soda and salt. Poke three holes in the ingredients with the handle of a wooden spoon. Pour oil into one hole. Do not mind if it overflows. Spoon the vinegar into a second hole and the vanilla into the last. Pour the cold water over the top and stir ingredients until smooth.
