Hurry Up Chocolate Cake

Still entering old hand-written recipes....

This is one of the fun cakes we made, where you mix everything in one pan.  Great for kids if you still let them eat flour and sugar -

1 1/2 cups flour
1 cups white sugar
3 rounded tbsps cocoa
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt

Sift all dry ingredients in a 9x9 pan until well blended.  Bump pan a little to level things off, then make three indentations in the mixture.  Mix together:

1 tsp vanilla
1 tsp vinegar
1/3 cup melted butter

and pour a little of this mixture into each of the three indentations.  Over the whole pan, pour:
1 cup lukewarm buttermilk or soured milk.  (I've used diluted yogurt, "whey" from strained yogurt or from making ricotta, or milk soured slightly with a bit of vinegar).

Stir and blend ingredients until smooth with no flour showing.  Shake gently to even out level and bake in a 350 oven for about 30 minutes.  Let it cool in the pan.
