I originally found this recipe in a Pillsbury Classic cookbook. Now it has become a family classic because my family loves this tasty snack cake. I often prepare the topping, put it in a baggie and take it with us to the lake cottage where I can make this simple cake with few ingredients and little effort. We make a quick stop for dairy products and we have to buy Bareman's sour cream (from Holland Michigan) it is divine! This cake makes the family happy and gives me time to read a good book lakeside.
