Chocolate Cake with Coffee Frosting Recipe

Chocolate Cake with Coffee Frosting Recipe

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

"Five stars for the frosting, but four stars for the cake. We found the cake itself to be a bit on the dry side, but the frosting is fantastic! It is easy to make and is as glossy as it looks in the above photo. I use the frosting for my smaller cakes and as a filling between cake layers. It sets up quickly, so I make separate batches if I am using it as a filling and as a glaze for the top layer, too."

"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!"

"Love this recipe, have been making it for years. cake is moist, and frosting very flavorful if you use coffee. Making it today for my son's birthday."

"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."
