Classic Tunnel of Fudge Cake

"This is that same cake that everyone seemed to make back in the '70's. Pillsbury discontinued their line of dry frosting mixes, and came up with their own revised version, which was NOT the same. I was thrilled to find this version in a food column from the "Minneapolis Star Tribune.""

Questions & Replies

  1. Where's the recipe using brownie mix in the Tunnel of Fudge cake? I can't find it.


  1. I made this using Pillsbury's updated recipe, since Jiffy has now discontinued their dry frosting mixes. First time in 40 years, and it turned out perfect! Saw another recipe, substituting Fudge brownie mix. Lady said it worked, but I haven't tried it yet. I will at some point. Mixing dry ingredients in by hand is extremely difficult for me. Has anyone tried using the Stir speed on a Kitchen Aid mixer?
  2. While cooling it "fell" Did or has this happened to anyone else?
  3. I have always wanted to try the Tunnel of Fudge Cake, but I was disappointed. It just wasn't all that chocolaty! I expected a lot more chocolate flavor in the cake. Thanks for sharing, though!
  4. Yooper, I have my mom's "Rich 'n Easy Tunnel of Fudge Cake" recipe from the 70's on my desk as I type. I knew they discontinued the Pillsbury frosting mix, but didn't know that there was the Jiffy frosting substitute! This cake brings back so many memories for me, as a child, in my mom's kitchen. I LOVED this cake! It was so rich and fudgey and great served warm. Thanks for posting this recipe. I can make it now for my kids!
  5. Hi yooper, what a find! We used to make this almost every week - we would hide it from our families so that there would be enough for company! This was the rage! We made it for every holiday, birthday, any event that we could bake it for. It was very gooey, and so chocolatey, and didn't even taste as it had anything pre-mixed in it. Great! Thanks for posting, Diane :=)


What can I say about myself that hasn't already been mentioned in the police reports? Just kidding! I'm a single guy who loves to cook! Good thing, or I'd starve or go broke eating out! I love to read, horror and mysteries are my favorite. Love music, (except rap) and I'm a huge Green Bay Packer Fan!
