Indulge in the ultimate chocolate treat with this recipe for Tunnel of Fudge Cake III. This decadent dessert features a moist chocolate cake with a gooey fudge center, topped with a luscious chocolate glaze. Perfect for special occasions or when you need a little extra indulgence in your life.


  • 1 3/4 cups unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 6 large eggs
  • 2 cups powdered sugar
  • 2 1/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 2 cups chopped walnuts
  • 1 3/4 cups chocolate chips
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt


  1. Preheat the oven to 350°F (175°C). Grease and flour a fluted tube pan (Bundt pan).
  2. In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition.
  3. Gradually add the powdered sugar to the butter mixture, beating until well blended. Stir in the flour, cocoa powder, chopped walnuts, chocolate chips, vanilla extract, and salt until just combined.
  4. Pour the batter into the prepared pan, spreading it evenly.
  5. Bake for 60-65 minutes, or until a toothpick inserted into the center comes out with moist crumbs.
  6. Allow the cake to cool in the pan for 1 hour. Then, carefully remove the cake from the pan and cool completely on a wire rack.
  7. For the chocolate glaze, melt 1/2 cup of chocolate chips in a microwave-safe bowl. Heat in 30-second intervals, stirring after each, until smooth and melted. Drizzle the glaze over the cooled cake.
  8. Slice and serve the Tunnel of Fudge Cake, savoring the rich chocolate flavors and the delightful surprise of the fudgy center.
