Tunnel of Fudge Cake

User Rating 4.5 Star Rating (3 Reviews)


Here's a version of the original Bake-Off recipe. For the updated version, take a look at Updated Tunnel of Fudge Cake. It's important to use exact measurements in this cake, especially the amount of nuts, so the structure forms properly. You can find a dry frosting mix in the grocery store, but you'll need to buy several boxes as it's usually sized for just a one layer cake. If you can't find the mix at your store, ask your grocer to order it for you. Or look at the Jiffy web site for stores that carry it in your area.

Prep Time: 25 minutes

Cook Time: 1 hour

Total Time: 1 hour, 25 minutes

Yield: 16 servings


  • 1-1/2 cups butter, softened (three sticks)
  • 1 cup sugar
  • 1/2 cup brown sugar
  • 6 eggs
  • 2 cups flour
  • 3-1/3 cups dry fudge frosting mix powder
  • 2 cups chopped pecans


Generously grease a 12 cup fluted bundt pan with solid shortening and set aside, OR use baking spray containing just before you pour the batter into the pan. Preheat oven to 350 degrees F.

In a large bowl, with mixer, cream butter until fluffy. Gradually add sugar and brown sugar, beating until light and combined. Add eggs, one at a time, beating well after each until mixture is smooth. With a spoon, add flour, dry frosting mix and nuts to batter until combined. Now spray the bundt pan with the baking spray, and pour batter into prepared pan.

Bake at 350 degrees for 60-65 minutes. Test after 60 minutes by looking for a dry, shiny brownie crust. You can't use traditional doneness tests for this cake because of the soft fudge center. Cool the cake in the pan on a rack until lukewarm (this is important!). Then turn onto a serving place and cool completely. You can drizzle it with some frosting or sprinkle it with powdered sugar, but as Dinah Shore said 'this lily needs no gilding!' Store tightly covered.

Can't find dry frosting mix . . . ;-(, Guest spransam

I love this recipe but haven't been able to make as written. I used to be able to find Jiffy fudge frosting mix (single layer size), but haven't been able to locate in any of a number of chains recently. I live in the Triangle area in North Carolina. Any suggestions?
