Step 1

Preheat your oven to 350 degrees F.

Step 2

In an 8x8-inch ungreased cake pan, sift the flour, salt, cocoa, baking soda, and sugar together.

Step 3

Form three depressions in the dry ingredients mixture, resulting in three separate wells. Then pour vinegar into one well, oil into the next, and vanilla into the last.

Step 4

Pour water over the top, then stir very well with a fork.

Step 5

Bake at 350 degrees F until a toothpick inserted into the center comes out clean, about 30-40 minutes.

Step 6

Top with a frosting of your choice, if desired, or eat it on its own!
