Preheat the oven to 350 degrees F (175 degrees C).
Sift all the dry ingredients into an ungreased 8" cake pan and spread.
Use your finger to make three holes in the dry ingredients. Put the vanilla in one hole, the vinegar in the second hole and vegetable oil in the third hole. Pour the water over everything and stir until the batter is smooth. Make sure to get the corners of the pan!
Bake at 350 for about 30 minutes or until the cake starts to shrink in from the sides.
Top it with whatever you’d like, but I like powdered sugar and fruit.
