Sour Cream Coffee Cake

"This Sour Cream Coffee Cake is a rich decadent buttery cake with a generous layer of walnut streusel through the center and over the top. My husband I really enjoy this cake with a hot cup of coffee. I love to serve this for brunch along with Cheesy Pepper Asparagus Breakfast Casserole and Summer Fruit Salad.If your family is anything like mine than they just love a good coffee cake. This is one of our absolute favorite coffee cakes. "
