Bittersweet Chocolate Cake with Prune Purée and Hazelnuts
After my company catered a party spotlighting foods from the state of Oregon, we were left with several pounds of fresh hazelnuts from the Willamette Valley, the capital of U.S. hazelnut production. We added the nuts to a flourless chocolate cake, and the result was this dark, rich confection with fruity undertones. Maple sugar, which is simply dehydrated maple syrup, is sold at most health food stores, but you may substitute any dry sugar. Serve this cake with vanilla-spiked whipped cream.
