  Categories: Cakes, Desserts, Chocolate
       Yield: 8 servings
  
       3 c  Flour
   1 1/4 c  Cocoa
   1 1/2 ts Baking soda
   1 1/2 ts Baking powder
   1 1/2 ts Ground cinnamon
   2 1/4 c  Buttermilk
   1 1/2 c  Thick sour cream
   1 1/2 tb Instant coffee crystals
       2 c  Sweet butter
   2 1/4 c  Sugar
   2 1/4 c  10x powdered sugar
       3    Eggs
   2 1/4 c  Heavy cream
  
   I.  THE CAKE:
       1. Preheat oven to 350 degrees F.  Grease 3 round, 9" cake pans.  Line
   bottoms with greased wax paper.
       2. Sift together flour, 3/4 c cocoa, baking soda, baking powder and
   cinnamon. Mix in buttermilk and coffee (dissolve coffee in an equal amount
   of hot water first.)
       3. Cream 1 1/2 c butter with the sugar until light and fluffy. Add the
   eggs one at a time until thick.  Beating on low speed, slowly mix in
   buttermilk mixture.  Beat 'til well blended.  Bake about 35 minutes, or
   until a straw comes out clean.
       4. Remove to racks to cool.  After they are cooled, put in 'fridge'.
   After 1 hour in 'fridge', split each in half (see note at bottom.) Wrap
   each layer in wax paper or plastic wrap, and freeze immediately.
   II. SOUR CREAM FILLING:
       1. Beat 3/4 c heavy cream, gradually adding 3/4 c 10x sugar until
   stiff.
       2. Gently fold in 3/4 c sour cream.  Set aside in 'fridge' (covered.)
   III. CHOCOLATE SOUR CREAM FROSTING:
       1. Melt remaining (1/2 c) butter.  Add 1/2 c 10x sugar and remaining
   (1/2 c) cocoa.  Stir with a wire whisk over low heat until smooth; cool.
       2. Beat remaining (1 1/2 c) heavy cream; add remaining (1 1/2 c) 10x
   sugar until soft peaks form.  Add cooled chocolate mixture; beat until
   stiff.  Fold in remaining (3/4 c) sour cream.
   IV. CONSTRUCTION:
       1. Build layers from the bottom up as follows:
       2. Cake, 1/3 the filling, cake, 2/3 c frosting.
       3. Repeat above twice, for total of six layers.
       4. Put remaining frosting on sides.
       5. Chill two hours before serving.
      Note: The cakes must be well-chilled before assembly, or they will
   disintegrate under their own weight during assembly.  If the cake tops
   rose during baking, the layers will not stack well.  You will need to
   slice the excess off *after* chilling, but *before* splitting into layers.
