Tunnel of Fudge Cake
Tunnel of Fudge cake was made famous by the Pillsbury Bake-Off. This version from America’s Test Kitchen is chocolatey and indulgent, as the name would suggest.
Hello beautiful!
This cake just screams indulgent with it’s chocolatey cake filled with a gooey underbaked center and topped with a chocolate glaze. It’s the perfect dessert to impress friends, family members, or that special someone in your life.
I made this cake for dinner with some friends. We all went back for seconds. As you can see in the pictures, I overbaked mine a smidge since my tunnel wasn’t quite as gooey as other pictures I’ve seen of this cake. I can tell you that I’ve made it again since taking these pictures and baked it a few minutes less and it had a more gooey-underbaked center. So my suggestion is to take the cake out a little before you think you need to.
I served the cake with some fresh raspberries and at the last second added some freshly whipped cream to the table as well. Even for this chocolate lover, I enjoyed the berries and cream to cut through the intense chocolateness coming from this cake.
I love the tip from America’s Test Kitchen to paint the inside of the bundt pan with a melted butter and cocoa mixture. Not only was it fun to do, it yielded a cake that came out of it’s pan with no issues. I’m definitely going to be using that trick for other chocolate bundt cakes in the future.

Yield: Serves 12-14
Ingredients:
For the Pan
1 Tbsp Dutch-processed cocoa powder
1 Tbsp unsalted butter, melted
For the Cake
1/2 cup boiling water
2 oz bittersweet chocolate, chopped
2 cups flour
3/4 cup Dutch-processed cocoa powder
2 cups powdered sugar
1 tsp salt
5 eggs, at room temperature
1 Tbsp vanilla
1 cup sugar
3/4 cup packed brown sugar
20 Tbsp unsalted butter, at room temperature
For the Glaze
3/4 cup heavy cream
1/4 cup light corn syrup
8 oz bittersweet chocolate, finely chopped
1/2 tsp vanilla
Directions:
For the Pan
Preheat the oven to 350 degF. In a small bowl, whisk together the cocoa powder and melted butter. Use a pastry brush to evenly coat the inside of a 12-cup bundt pan.
For the Cake
In a medium bowl, pour the boiling water over the chopped chocolate. Let stand for a minute, then whisk until smooth. In a medium bowl, combine the flour, cocoa powder, powdered sugar, and salt. Combine the eggs and vanilla in a liquid measuring cup and beat lightly.
In the bowl of an electric mixer, combine the granulated sugar, brown sugar, and butter. Beat on medium-high speed until light and fluffy, about 2 minutes. With the mixer on low speed, add in the egg mixture just until combined. Add the chocolate mixture and mix until incorporated. Blend in the dry ingredients until just combined.
Spread the batter into the prepared pan. Bake for about 45 minutes or until the edges of the cake begin to pull away from the pan.
Allow the cake to cool on a wire rack for 2 hours before inverting onto a cake platter. Allow to cool completely, about 2 more hours.
For the Glaze
Combine the cream, corn syrup, and chocolate in a small saucepan. Heat over medium heat, stirring frequently, until smooth. Blend in the vanilla. Set aside for about 30 minutes, until slightly thickened. Drizzle the glaze over the cake and let set for at least 10 minutes before slicing.

I love the idea of perfect party minicakes!! They look delish! Great job! That flour picture is so funny. I can’t tell you how many times I’ve done that – flour on the counter, on my KA, in my hair, on my face!

Yum! Love the raspberry/lemon combo, and the mini cakes are adorable 🙂
Well done – what an innovative variation. They look so cute!
I can totally relate to the slippery effect.
Your cake looks beautiful!
You did a lovely job on all your mini cakes.

Adorable! Your KA and mine would be best friends. ‘Chuck’ is always filthy. Poor guy. He gets cleaned up, just to be coated again. 😉
How cute! Making mini-cakes is a great idea. Next time I make this cake I will try that, I still have a HUGE cake in the fridge I need to eat :-/
Cheers!
Great idea on the mini cakes. They are really cute. Great job. To the next challenge we go.
beautifully done!!! love it!!!
I love the little cakes! Plus the raspberries! Yummy!
The mini cakes look really amazing!
The minicakes are wonderful! Now, you’ll need my address to send one…Libby 😉
Love the idea of the mini cakes, that’s so adorable!
Mini-cakes are definitely more work than one large cake! They’re so cute though.
What a cute idea! They look adorable!
I love desserts in miniature and your mini cakes look beautiful. I think I will most definitely be making mini cakes sometime in the near future – thank you for the wonderful idea!

I’m loving the mini versions! The cake looks fantastic. Mmmmm!
I made mini ones too. I hate to tell you but it is way easier to frost a whole cake than mini ones. 🙂
Looks great.
Beautiful!! You did a gorgeous job :O)
These individual cakes look pretty…well done!
Really cute idea to make individual cakes, I love that. Great job!
I adore your minicakes. V lovely.

Oh! the minicakes are just the best idea ever. I probably should have done that with my oh-so flat cakes. How great.
Mini cakes -what a great idea! I think I’m going to have to try that here pretty soon. Looks like a delicious lot of fun. Especially the part where you get to eat the scraps. I think this cake was some of the best I’ve had.
What cute little mini cakes! Aren’t things just better when they’re mini?
Great work!
I love the little cakes and the picture with the raspberry and lemon zest is so enticing!
Perfect!

Another messy baker here! And I love the mini cakes – I’m nice to see its as low-tech as cutting circles out of larger pieces rather than trying to bake a bunch of cakes in miniature pans.
Jen,
Your little cakes are gorgeous! I too love swiss buttercream … congratulations on a job well done!
wow, that takes some patience, putting all those cakes together! They are just the cutest though. ~ JMom
so petite and cute!
