We like a glass of ice-cold milk to accompany this cake recipe. Baked with dried cranberries, golden raisins, and ginger, the cake gets a gentle tang from sour cream.
Preheat the oven to 350 degrees. Butter and flour a six-cup Bundt pan, and set aside. Place the grated ginger, water, cranberries, and raisins in a small saucepan, and bring to a boil. Reduce to a simmer, and cook until the liquid has evaporated, about 5 minutes. Set aside to cool.
In a medium bowl, sift together the flour, cocoa, baking powder, baking soda, salt, and ground ginger. Place the butter and sugar in the bowl of an electric mixer fitted with the whisk attachment; beat on medium-high speed until light and fluffy, 2 to 3 minutes. Add the eggs, one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Stir in the vanilla. Add the flour mixture and sour cream in alternate small batches, starting and ending with the flour mixture; beat just until combined. Fold in dried fruit mixture.
Pour the batter into the prepared pan, and bake for 40 to 50 minutes, or until a cake tester inserted into center comes out clean. Remove from the oven, transfer to a wire rack, and let cake cool in the pan for 30 minutes. Invert the cake onto a wire rack to cool completely.
Place cake on a cake plate or serving platter, and tuck pieces of waxed paper under the edges of the cake to keep the plate clean. Apply a thick coating of chocolate fudge frosting to cake, using a small offset or rubber spatula. Remove waxed paper before serving.
While this cake tastes best the same day it is made, it can be stored in an airtight container at room temperature for up to 2 days. To keep the frosting rich and glossy, do not refrigerate the finished cake.
