Easiest Chocolate Cake Ever!

My mother used to make a variety of this easy delicious chocolate cake,  and it's definitely a no fail recipe and creates the most moist cake ever!  I had some friends coming into town for the day, and I just whipped it up before they came over.

Easiest Cake Recipe Ever:
preheat oven to 350 degrees F.

Whisk together in large measuring cup or medium bowl:
1/3 cup vegetable oil
1 tsp apple cider vinegar
1 tsp vanilla
1 cup warm water

In a large bowl sift together:
1 1/4 cup flour
1 cup sugar
1/3 cup cocoa powder
1 tsp baking soda
1/2 tsp salt

Pour contents of measuring cup into the large bowl of wet ingredients and stir/whisk until there are no large lumps.  Small lumps are okay.  You don't want to over stir cake batter, or it will get gummy. Pour into an 8x8 round or square tin, smoothing it out on top. NO JUMPING!
Bake for 35-40 minutes, or until a toothpick comes out clean from the center.
For the ganache, just make your favorite ganache recipe, or follow what I did. I just heated soy milk (enough to almost cover 4 ounces of semi-sweet chocolate) over medium heat in a double boiler until the chocolate is just over half way melted, whisking and keeping an eye on it. Put in a dash of vanilla, take it off the heat, and continue to whisk until the whole thing is melted. If it hasn't quite melted yet, hold it over the steamy heat and whisk some more. You can finish it off by stirring a teaspoon of margarine in at the end, until melted, and it will make it nice and shiny.  
Then when the cake was cool, I poured the ganache over the cake, and wait for it to all set. Refrigerate if you somehow don't eat all the cake within the hour!  
SIDENOTE:    You can also melt chocolate in a microwave!  Just watch that informative video.
