In my quest to capture American desserts, I've polled friends and relatives for favorites from their childhoods. Among Michiganders, especially those with Detroit roots, Sanders' Bumpy Cake commands some serious nostalgia points. What is Bumpy Cake? Short answer: addictive. Long answer: a Devil's Food Cake with stripes of sugary buttercream topped with "pourable fudge" frosting. Yes, pourable fudge frosting.

Bumpy Cake is a Detroit tradition. This moist, dark chocolate cake has a sweet layer of buttercream topped with a fudgy, almost caramelly chocolate frosting. It's ideal for chocolate lovers, and though it has three separate components that require freezer cooling to obtain picture perfect results, it's well worth the effort.
