This was a late night creation. I had a cake that needed a quick fix and little booze (yes booze). I hope you enjoy this recipe as much as we have. If you have children, use Hazelnut flavoring instead of the Frangelico. I have had to sub the booze for children's cakes. It works fine--might want to add a wee-bit extra though.THE POWDERED SUGAR MEASUREMENT IS A CLOSE APPROXIMATION. USE MORE OR LESS FOR DESIRED THICKNESS......this is enough icing for 9x11 cake.
