2 1/2 c All purpose flour
1/2 c Cocoa
2 ts Vanilla
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.

inserted in center comes out clean. Cool in pan on a wire rack.
Sprinkle with powdered sugar, if desired.
