My family loved this cake. This is the 2nd time that I've made this cake, and because we loved it so much I made 2 this time- 1 w/ nuts an 1 w/o. The frosting is delicious; I agree that it makes the cake! I took Florence's advice and reduced the powdered sugar to 2 cups and that seemed about right. I also used "light" sour cream and milk instead of half-and-half and it was still rich and yummy. Enjoy!
