Chocolate Cake, I Just Love This One - cooking recipe

Ingredients

For the cake
2 1/2 cups loosely packed brown sugar
2 1/4 cups sifted flour
2 teaspoons baking soda
1/2 cup butter, softened
3 eggs
3 unsweetened chocolate squares (80g, or 85% or higher)
1 1/2 teaspoons pure vanilla extract
1 cup sour cream
1 cup boiling water, and
1 pinch salt
Butter cream frosting
1 lb butter (soft)
2 lbs icing sugar
1 tablespoon milk (as needed)

Preparation

Preheat oven to 350\u00b0F.
Melt chocolate in microwave (30 seconds at a time) or in a double boiler.
Grease two 9-inch cake pans.
Sift together flour, baking soda, and salt.
In a separate larger bowl of an electric mixer, beat butter until light.
Add sugar and continue beating.
Add eggs one at a time, scraping bowl well after each addition.
Beat on high speed for 5 minutes.
Add vanilla and chocolate.
Stir in sifted dry ingredients alternately with sour cream (starting and ending with flour, i.e. add some flour, then some sour cream, then more flour -- etc).
Stir in boiling water.
Pour into pans.
Bake for 35 minutes (start testing for doneness after about 27 minutes; if there are a few moist crumbs on the tester, it's ok to take it out).
Cool in pans for 5 to 10 minutes. Remove to a rack and let cool completely before icing.
To make the frosting: Mix all the frosting ingredients together in mixer. Once it is well mixed, frost the cake generously.
Enjoy :-D.
