Delicious icing. I put it on a chocolate cake and it was gorgeous.  -  08 Aug 2012

Excellent butter cream frosting! I couldn't have been more pleased. I scaled this to 32 servings (4 cups powdered sugar) for my 9" layer cake and still wish I would have had more for decorating. I beat the butter a few minutes until fluffy, gradually added the full amount of powdered sugar called for and enough coffee until I got it to the consistency I wanted. I beat the frosting for several more minutes after that, until it was light, creamy, fluffy and silky smooth. This is pleasantly light chocolate - not too strong, and not too sweet, with just a hint of coffee flavor. I found the proportions of all ingredients perfect, and this will be a recipe I'll certainly be comfortable referring to again, whether I use it with the coffee or without, with the chocolate or just as a traditional vanilla buttercream. This frosting as written, however, was the perfect choice for "Chocolate Mocha Cake I," also from this site.  -  04 Feb 2010  (Review from Allrecipes US | Canada)

Great consistency, but I found this frosting too sweet with too little flavour. I increased the coffee and cocoa to about 3 tablespoons each to increase the mocha flavour.  -  10 Sep 2005  (Review from Allrecipes US | Canada)
