1963-1979: Tunnel of Fudge Cake
It's been over a year since I've written about a cake from American Cake. I posted the hot milk sponge cake in January 2018. My goal of baking through each decade wasn't achieved; I began flipping through the book to find recipes as I wanted them. I've jumped a couple decades to make the tunnel of fudge cake.
The tunnel of fudge cake was originally a second-place cake in the 1966 Pillsbury Bake-Off. The cake achieved its fudge tunnel from Pillsbury Double Dutch Fudge Buttercream dry frosting mix. It's not a product I've ever seen in stores (or eaten). My assumption is that canned frosting eliminated the need for a dry frosting mix. There are still dry frosting mixes out there, but as you can see from the photo, the fudge is achievable without it. To achieve the tunnel of fudge, simply under-bake your cake!
Because the cake is under-baked, it's not easy to tell if it's done; you have to trust the time on the recipe and allow it to cool before turning it out of the bundt pan and slicing.
There are plenty of tunnel of fudge cake recipes for you to use. If you Google Pillsbury Double Dutch Fudge Buttercream dry frosting mix, it's the first result that comes up for the Pillsbury page.
