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!!!!!!!!
This recipe is so easy and delicious!!! Super moist.
This is an excellent recipe. In my opinion the
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.
