Grease a ring mold, and cover the bottom with parchment paper.
Preheat the oven to 350ºF.
Sift the flour, baking soda, salt and cocoa in a bowl, and mix with a spoon.
Make a well in the center and add the oil, vanilla, vinegar and two cups cold water. Mix with a whisk. The mixture is going to have a very thick texture.
Add the sugar and stir with a spoon, you will see how the texture changes and becomes more liquid.
Pour into the prepared baking pan and bake for 1 hour.
Let it cool before unmolding and serving.
