Recipe Comments & Reviews

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!
So super easy and delicious!!!!!!!!! THUMBS UP!!! Super Moist!!!!!!!!

frosting makes the cake. The cake is very moist
and it has a tender crumb.It will go very
quickly when you serve it. The only problem is
the frosting is a little bit too sweet but you
can adjust that by using less powdered sugar.
