I work evenings in the operating room at our local hospital. Since getting away for meals can be difficult, we occasionally plan potlucks. I'm frequently asked to bring my "chocolate cake with the special icing". -Irene Peery Charlottesville, Virginia

"Wish I had read all the reviews before making this recipe. The icing is awesome but, like many others , we found the cake itself to be a little dry. I love the idea of adding some sour cream to the mix. The only thing I added was a teaspoonful of powdered espresso instant coffee to the cake mixture. Will try it again with some small changes."

"I made this cake today with a couple modifications. I used grapeseed oil instead of canola oil, and for the buttermilk, I used an almond milk and vinegar mixture. The cake turned out great, and we all enjoyed it for my husband's birthday! I would definitely make this cake again!"

"I can't say I tried the whole recipe- I only tried the icing part and made my favorite chocolate cake recipe for it. The icing is a nice change from very sugary icings and is pretty easy. If you do not have cornstarch on hand you can try doubling that amount and using flour instead- it works great. The icing makes the cake seem extra-moist and is so yummy!"

"The cake was moist and pretty good, but I've had better. The frosting however, is amazing! I will use this frosting on a better cake next time."

"Very good recipe, very moist. For those of you who said this recipe was dry, try sifting your flour then measure out by spooning into measuring cup and level off with spoon."

"I doubled this recipe for an adult birthday & it was amazing! The cake itself was fantastic -- not too sweet & nicely moist. The icing was delicious (used strong coffee instead of hot water). My sisters asked for the recipe. Definitely becomes a "favourite" in my recipe box."
