Three Layer Chocolate Cake

This cake is a birthday tradition in our family, and has been since 1968 when I found the recipe in the Time/Life American Cooking cookbook. The frosting is about the only thing I still use sour cream for, having discovered Trader Joe's 2% Greek yogurt. As good as that yogurt is though, I don't think it would cut it for frosting.

6 ounces unsweetened chocolate squares
12 T butter (1-1/2 sticks), at room temperature
2 cups of sugar
4 eggs, at room temperature
1 t vanilla

2 cups flour
1-1/2 teaspoons baking powder
1/4 t salt (omit if using salted butter)

1-1/2 cups of milk

FROSTING

3 ounces walnut pieces
21 ounces semi-sweet chocolate
1/4 t salt
1-1/2 cups sour cream, at room temperature


Melt the unsweetened chocolate and cool it to room temperature. Cream the butter and sugar until light and fluffy. Beat in the eggs singly incorporating well after each addition, then the melted chocolate and vanilla.

Sift together the dry ingredients. Add 1/4 cup of the dry ingredients into the batter, then 1/4 cup of milk. Continue alternating milk and dry ingredients, incorporating well after each addition until the batter is smooth.

Preheat the oven to 375 degrees. On a baking sheet, toast the walnuts until they are lightly golden and fragrant. If you are over 45, set a timer so you don't forget about them. Remove and cool to room temperature.

Meanwhile, butter and flour three 9" cake pans, and line the bottom of each pan with parchment paper. Divide the batter equally AMONG (NOT between -- bad grammar is almost as bad as bad food!)the pans. Bake the cakes for about 20 minutes -- until the cakes are pulling away from the sides of the pan a bit and are firm to the touch. A toothpick or cake taster should come out clean. Turn the cakes out on racks to cool and remove the parchment paper.

Make the frosting: Melt the chocolate. Add it to the sour cream and salt and blend until well combined.

Frost the top of each cake(about a quarter of an inch thick). Stack the layers on a cake plate and frost the sides. Add additional frosting to the top if you have it. Strew the walnut pieces on top of the cake and push them gently into the frosting so that they adhere.
