Tunnel of Fudge Cake

READY IN: 1hr 10mins
Recipe by Kaarin

So rich and gooey! This cake is made completely from scratch-no mixes required. The secret to the fudgy tunnel is the addition of the nuts-don't be stingy with them! It's from Pillsbury Best of the Bakeoff.

Top Review by Vseward Chef-V

This is an awesome recipe. Not only was it beautiful but tasted like chocolate heaven... more like a brownie or hot fudge cake. You're right you can't be stingy with the walnuts or this cake won't turn out. I've made it several times, and each time great raves and reviews. Thanks for posting, I have it saved in my cookbook online and have uploaded a picture that shows just how inviting this cake is. ~V
