I made the recipe as described EXCEPT for the Grand Marnier. I used 1/4 c freshly squeezed OJ. It was delicious and buttery! Yum! The only thing is, my house is cold and so the frosting was too stiff, in my opinion. Next time, I will use only enough butter to have a nice, creamy consistency. Thank you, Martha and crew!
This recipe was not as good as I was hoping it would be - very expensive to make and the end result was too buttery.
