You can make the original Tunnel of Fudge Cake using frosting mix, or try this updated version made from scratch. The powdered sugar and cocoa in the recipe essentially replace the frosting mix. Be sure you follow this recipe exactly as written. Do not substitute any ingredients and be sure you use the full amount of nuts, otherwise the recipe will fail.

Prep Time: 25 minutes

Cook Time: 48 minutes

Total Time: 1 hour, 13 minutes

Yield: Serves 16

Ingredients:

  • 1-1/2 cups butter, softened
  • 1 cup granulated sugar
  • 3/4 cup brown sugar
  • 2 (1-ounce) squares unsweetened chocolate, melted and cooled
  • 6 eggs
  • 2 cups sifted powdered sugar
  • 2 cups flour
  • 2/3 cup cocoa
  • 2 teaspoons vanilla
  • 2 cups chopped pecans or walnuts
  • 1/2 cup semisweet chocolate chips
  • 1 teaspoon vegetable oil

Preparation:

Preheat oven to 350 degrees F. Measure flour by lightly spooning the flour INTO the measuring cup, NOT by scooping the measuring cup into the flour. The scoop-and-level method is incorrect and will make this cake too dry.

In large bowl, combine butter, sugar, and brown sugar, and beat until mixture is light and fluffy. Add melted and cooled chocolate, beating until combined.

Add eggs, one at a time, beating thoroughly after each addition until eggs combine with butter mixture (this can take some time).

Sift the powdered sugar BEFORE you measure it. Gradually add powdered sugar to the batter, mixing well. By hand, stir in flour, cocoa, vanilla, and pecans until well blended.

Spray a 12 cup Bundt pan with nonstick baking spray with flour. Spoon batter into prepared pan. Bake at 350 degrees F for 48-54 minutes, until crust looks dry and shiny (traditional doneness tests won't work because of the soft fudge center). Cool cake in pan on rack for 1 hour, then invert onto serving plate and remove pan. Cool completely. If you bake the cake for the shorter period of time, it will have true fudge in the center. Bake it longer for a moist tunnel in the center.

In small microwave-safe bowl, place chocolate chips with oil. Microwave on 50% power for 2 minutes; stir. Continue microwaving until chocolate is melted and mixture is smooth. Pour into a small ziplock bag. Cut a tiny piece off the corner of the bag and pipe the chocolate over the cake, using a back-and-forth motion. Let cool.

Make sure that you measure flour correctly for this recipe. Don't skimp on the walnuts; they're critical to the cake structure. And don't over bake the cake or it may be dry and fall apart.

This is the first time I ever heard of and made this cake...It will NOT be the last time either. This cake is easy to make and fun to do. I make everything from scratch so this recipe just fit in very well... I read some of the reviews and I would like to tell the two who said it fell apart and that is Guest Patty and HLhudgins. The trick is to loosen the cake with spatula after an hour and then let it cool another hour. The fudge in the middle needs to harden so cake will stick together. Good luck ladies...
