Tunnel Of Fudge Cake

1 3/4 cups sugar
1 3/4 cups butter or margarine, softened
6 eggs
2 cups powdered sugar
2 1/4 cups all purpose or unbleached flour
3/4 cup unsweetened cocoa
2 cups chopped walnuts

Glaze
3/4 cup powdered sugar
1/4 cup unsweetened cocoa
4-6 tsp. milk

Heat oven to 350 degrees. Grease and flour a 12-cup Bundt pan (or a 10-inch tube pan). In a large bowl, combine sugar and butter or margarine; beat until light and fluffy. Add eggs 1 at a time, beating well after each addition. Gradually add 2 cups powdered sugar; blend well. By hand, stir in flour and remaining cake ingredients until well blended. Spoon batter into greased and floured pan and spread evenly.

Bake for 45 to 50 minutes or until top is set and edges are beginning to pull away from sides of pan. Cool upright in pan on wire rack 1 ½ hours. Invert onto serving plate and cool at least 2 hours.

In small bowl, combine glaze ingredients, adding enough milk for desired drizzling consistency. Spoon over top of cake, allowing some to run down sides. Store tightly covered.
