    Wow. I was somewhat cautious about this recipe, because uncooked eggs scare me a little. But I had a house full of 11-year-old boys, so I knew the cake would be eaten. It is *wonderful* frosting. I didn't use the rum ('cause of the kids), but other than that followed the recipe exactly. Smooth and creamy without being sickly sweet and fatty. I'll definitely make this again, though I admit I'm still a little queasy about the raw egg yolks.  -  23 May 2006  (Review from Allrecipes US | Canada)


    I made this recipe with my 4-year old grandson for his parents' anniversary. We substituted hot orange juice for the coffee and rum to accommodate individual taste. It was the fastest, easiest, tastiest recipe we've ever made! Lots of possibilities for variations!  -  18 Aug 2000  (Review from Allrecipes US | Canada)


    It tasted great, but was very thin. I had to add a lot of extra powdered sugar to make it thick enough to stand up to icing on a cake.  -  22 Feb 2003  (Review from Allrecipes US | Canada)
