1 c  Butter, softened
     1 c  Firmly packed brown sugar
 2 1/2 c  All purpose flour

     2 c  Sugar
     6    Large eggs
   1/4 ts Baking soda
     8 oz Sour cream
          Powdered sugar (optional)
 Beat butter at medium speed about 2 minutes. Gradually add sugar,
 beating at medium speed for 5-7 minutes. Add eggs, one at a time,
 beating just until yellow disappears.
 Combine flour, baking soda, and cocoa; add to creamed mixture
 alternately with sour cream, beginning and ending with flour mixture.
 Mix at low speed just until blended after each addition. Stir in
 vanilla. Spoon batter into a greased and floured 10-inch tube pan.
 Bake at 325F for 1 hour and 20 minutes or until a wooden pick
 inserted in center comes out clean. Cool in pan on a wire rack.
