I found this delicious version of a buttercream recipe in a book that I purchased from Amazon called Kauffeehaus by Rick Rodgers. This book is filled with delicious recipes of cakes, cookies, and donuts. I modified the recipe a little by adding 1/2 cup of icing sugar, which helped to thicken the consistency of the buttercream.
Did you add the icing sugar to the butter to beat or did you add it in another step?
I can't wait to try this!!! Thank you.
