Sour Cream Chocolate Cake

This is a delicious chocolate cake recipe I found a few years ago.  It's super creamy.  Enjoy!

4 squares (1 ounce each) unsweetened chocolate, melted and cooled
1 cup water
3/4 cup sour cream
1/4 cup shortening
1 tsp vanilla extract
2 eggs, beaten
2 cups all-purpose flour
2 cups sugar
1-1/4 tsp baking soda
1 tsp salt
1/2 tsp baking powder

FROSTING:
1/4 cup butter, softened
3 squares (1 ounce each) unsweetened chocolate, melted and cooled
3 cups confectioners' sugar
1/4 cup sour cream
3 Tbsp milk
2 tsp vanilla extract
dash of salt

1. In a mixing bowl, combine the first six ingredients; mix well.  Combine the dry ingredients; gradually add to the chocolate mixture.  Beat on low speed just until moistened.  Beat on high for 3 minutes.
2. Pour into two greased and floured 9-in. round baking pans (can also make 12 cupcakes).  Bake at 350 deg for 30 minutes or until a toothpick inserted near the center comes out clean.  Cool for 10 minutes before removing from pans to wire racks to cool completely.
3. In a mixing bowl, combine frosting ingredients.  beat until smooth and creamy.  Spread over cake.  Store in the refrigerator.
