Found on CakeCentral.com while researching the original recipe. I am personally not sure about this icing. I may try the other roux one. Originally posted by descakes. "This is the original Waldorf-Astoria Red Velvet Cake recipe and a huge favorite with family and clients alike! The Cream Cheese/Mascarpone Frosting is to die for:) I know it’s going to sound odd but give it a try and you’ll be delightfully surprised!" NOTE: I (cookfromscratch) tried this recipe yesterday and was sorely disappointed. It was a good recipe, but not lacking the flavor for Red Velvet.It was a lot of trouble for a good chocolate cake. The red color was also lacking, however, I did use natural food color due to allergies. I am going to keep looking. for a natural Red Velvet recipe.
