Egg whites help bind the ingredients of a cake together. However, certain adjustments, such as using a flour with high gluten content, contributes the same binding properties as egg whites in many recipes. Alternatively, an equivalent amount of egg substitute can be supplanted for eggs in many preparations.

Preheat the oven to 375 degrees Fahrenheit. Add the flour, cocoa powder, baking soda, sugar and salt to a baking pan. Incorporate all the ingredients thoroughly with a whisk.

Slowly add the oil, water and vanilla extract to the dry ingredients in the baking pan, fully mixing each amount before adding more. Add the vinegar and whisk thoroughly. Allow the batter to settle.

Place the pan in the oven and bake for approximately 25 to 30 minutes, or until the center is set. Remove and allow to cool.
