Recipe for Chocolate Tunnel Cake

This post may contain affiliate links. Read my disclosure policy.

When we were at the Dewey’s for the Super Bowl party Gram made a Chocolate Tunnel Cake. The cake was rich and chocolaty, but it gets even better, there was a surprise “tunnel” of cream cheese and mini chocolate chips in the middle. You bake the cake in a bundt pan, so the cake was pretty and delicious. When you slice it you can see the tunnel of cream cheese. It was a cool looking cake! Everyone loved it!

Thanks for sharing the recipe Gram!! We always enjoy your treats.

  1. Oh my! I have been looking for a recipe like this for my dad’s bundt pan and this looks fabulous! Oh yum!It is really beautiful!

  2. This looks awesome. I’d like to know why there’s vinegar in the recipe? From what I know, vinegar gives chocolate cakes a red hue. But what’s its purpose for this cake? This recipe is slightly different than the original Tunnel of Fudge Cake recipe winner from the Pillsbury bakeoff long ago. I’m gona make this bundt cake though! Still, why the vinegar? Thanks & I luv your cookie recipes!

    1. Ooooh, I know this one! Vinegar is an acid, baking soda is a base. Combined, they produce bubbles of carbon dioxide which make the cake rise. The chemical reaction doesn’t last long, though, so it’s important that once combined, you need to get the batter into the oven ASAP. For that reason, it might be a good idea to make the filling first.

  3. Mmmmm! Made this yesterday with two tweaks: coffee instead of water, and I didn’t have mini chips so I chopped up some regular-sized ones. The oil in the cake gave the outside an almost brownie-like chewiness (that’s a good thing). The tanginess of the cream cheese kept it from being too sweet. I love the fact that the whole thing only uses one egg; so many bundts take 4-6 & I hate using up half a carton just to bake a cake. If I were serving this to guests I would probably sprinkle some sifted powdered sugar over the top just to pretty it up a little, but it doesn’t really need any topping at all.
