- 1 cup butter or margarine
- 1 cup water
- 1/4 cup baking cocoa
- 2 cups all-purpose flour

- 1/2 cup chopped walnuts, toasted
- In a saucepan, bring butter, water and cocoa to a boil; whisk until smooth. Cool to room temperature. In a mixing bowl, combine flour, sugar and salt. Add cocoa mixture; beat on low speed just until combined. Add sour cream, eggs and baking soda; blend until smooth. Pour into a greased 13-in. x 9-in. x 2-in. baking pan.

Combine the confectioners' sugar and cocoa; gradually add to butter. Beat in the vanilla and enough milk to achieve spreading consistency. Frost the cake. Sprinkle with nuts. Refrigerate until serving.
