food tube pan. Dust with flour; tap out excess. 2. In a large bowl, beat together butter and sugar with an electric mixer on medium speed until light and fluffly, 1 to 2 minutes. Add eggs, one at a time, beating well after each addition. Gradually add 2 cups powdered sugar, beating until well blended. By hand, stir in flour, 3/4 cup cocoa, and nuts; mix until well blended. Spoon batter into prepared pan and spread evenly. 3. Bake 58 to 62 minutes. Since this cake has a soft tunnel of fudge, ordinary doneness test cannot be used. Accurate oven temperature and baking time are critical. Let cake cool upright in pan on a rack for 1 hour; then invert onto serving plate and let cool completely. 4. To make glaze, in a small bowl, combine remaining 3/4 cup powdered sugar, remaining 1/4 cup cocoa, and milk. Mix until well blended. Spoon glaze over top of cool cake, allowing some to run down sides. Store cake tightly covered. ** Nuts are essential for the success of this recipe.
