Prepare 2, 9 inch diameter pans with wax paper on the bottom to reduce stick. Then preheat your oven for 350 degrees and get a timer set for 30 minutes (note do not start it yet!)
1/3 cup butter OR margarine (note not both)
1 2/3 cups white sugar
In a bowl with a kitchen-Aid
3 egg whites Or 2 whole eggs (note not both)
Beat Until Smooth
1 teaspoon vanilla
1/2 cup sour cream OR yogurt
3 square (3 oz) of melted unsweetened chocolate
Mix Together Well in Separate Container
2 cups all purpose flower
1 1/2 teaspoon salt
1 1/2 teaspoon baking soda
Mix Together Well in Another Separate Container
1 cup milk
1 tablespoon vinegar (this curdles the milk making the cake slightly sour so if you don't like sour take this out)
Add the flour mixture and milk mixture a little bit at a time into the bowl with everything else. Then when that is done put 1/2 of the batter in each pan then start the 30 minute timer. Then take the icing and cover the top of both cakes with a thin layer of icing, stick them together cover the sides and you're done. (note don't touch the metal pans with your bare hands)
What is a cake without icing? That is even worse than bread without butter! Well when the cake is almost done start this recipe.
1 cup melted semisweet chocolate chips.
1 cup sour cream OR 1 cup plain yogurt
By the way something you should try is putting a layer of cherries between the2 halves and double the icing recipe.
