Recipe by TasteTester
This is an unusual cake; good for those times when you don't want something too rich or sweet. It can be made ahead and frozen up to 2 months. Just wait until the cake is cool and wrap it tightly in 2 layers of heavy-duty aluminum foil. When ready to use, just take the cake out of the freezer at least 4 hours before serving and let it thaw -- unwrapped -- at room temperature. (Cooking time does not include the 2 hours for cooling the cake.)
