Sour Cream Walnut Coffee Cake

Response to request for "Old but Goodie Recipes", the following came from a very neat friend who went on the River Cruise in Europe ...girl trip. Remember my blogs about that? Teresa lives in Maryland and was a working girl and can imagine her making this and taking it to work often.
Here's her recipe...
