Epiphany Cake

I made a Christmasy cake for the Feast of Epiphany. It's rich enough for Three Kings, and deliciously uses up the left-over fresh cranberries and dates and walnuts from the holidays. (I've always been the Queen of Leftovers, and find a way to use every scrap, but this season of unemployment has me aware of the contribution I can make that way.) Nice change from my other recipe for Cranberry Cake.
Winger was waiting with anticipation, so he snapped a photo as I was drizzling on the icing.
