My Mom made one of the best Sour Cream Coffee cakes that I have ever tasted. I've tried other recipes and none of them were as moist as my Mom's. If you are looking for a moist and delicious Sour Cream Coffee cake, well look no further and make this one. I've added a couple of variations at the bottom. My neighbors son always asks me when I am going to make him this cake with the chocolate chips.
