I remember this cake from when I was a kid. I also made it for my kids and let them make it too. It is so easy and fun to make! Note that it is made without eggs.

3 cups flour
2 cups sugar
1 teaspoon salt
2 teaspoons baking soda
6 tablespoons cocoa
3/4 cups vegetable oil
2 cups water (room temperature)
2 tablespoons vinegar
1-1/2 teaspoon vanilla

Put first 5 ingredients in 9-inch pan and stir with fork until well mixed.

Make 3 wells in the dry ingredients. Put vanilla in first well, vinegar in the second one, and oil in the third.

Pour water over all and thoroughly mix.

Bake at 350 degrees for 30 minutes.
