Recipe Comments & Reviews

Great cake,my 9yr old says it's the best cake ever.
A thin layer of creamy peanut butter between the cake and frosting is delicious!!!!
Just made this cake for the first time for our Chili & Chocolate Party at work. Hope I win the "blue ribbon". One person had a sample and loved it! I guess this recipe is a keeper.
Excellent cake!! I've made this several times and received raves. Easy and delicious, this recipe is a keeper!
I have been making this cake for years, accidently put in 1 cup of sour cream once, made it that way ever since. I also have made it in a 13x9 and it just cooks a little longer. The frosting seeps into the cake and becomes fudgy goodness. Just the right amout of chocolate - not too rich.
This is the best sheet cake I have ever had...I have used it for pot lucks, bake sales, and birthday cake and everyone always raves about how wonderful it is.
This recipe is so easy and for anyone with a chocolate craving this is the cake to make. My friends just loved it !
Land O' Lakes put a similar recipe out over 30 years ago in a brochure and I've used it ever since. It called for unsweetened chocolate squares instead of cocoa but I've often substituted for it. My daughter asked for the recipe so I came back to Land O' Lakes first before typing it all out. Thank you for great recipes!
This chocolate cake is fantastic. I will be making this cake again.
Easy and delicious.
I have made this recipe twice and shared with friends and family. Everyone loves it!!
