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."

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!

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!
