Since mentioning my obsession with Bundt cake, I've received four recipes and this tidbit: "Google Tunnel of Fudge."
Preemptively cringing in case my results turned out obscene, I typed "Tunnel of Fudge" into my browser's search box.
Aha! That's the chocolate Bundt with the gooey center that I remembered from childhood! But apparently it's hard to make, due to the scarcity of some key ingredient. Lots of scratch recipes listed workarounds but I admit that I was getting apprehensive about this project as I read about the dangers of scooping flour versus lightly measuring it into a cup by spoon. Goodness. Cake is complicated.
A few tentative clicks then took me to this.
It looks like the same mix I'd have used as a kid.
I ordered it. I guess we'll find out. But I gotta admit, paying $8 plus shipping for a cake mix does strike me as a bit silly.
