I first tasted this wonderful cake back in the early 80's on a trip to my grandmother's house back in Tennessee. It was on a hot summer day and she had this cake in the refrigerator and served it nice and cold. Holy cow, what a refreshing summer treat it was! She wrote out this recipe for me and I kept it for years, but lost it for a time. I found it in one of those church ladies cook books several years later and wanted to make sure that I didn't lose it again. I've always liked this better refrigerated, but you can serve it warm or room temperature or whatever way that you like it best!
