Yes, I had a small taste of this frosting when I made the Guinness cupcakes the other day....and it was phenomenal.....yes, I am sugar and fat deprived, but nevertheless, this is a to die for, yummy frosting. I adapted it from The Cupcakery. Give it a try...and don't skip the lemon, it makes it pop.
Bailey's Irish Cream buttercream
1 stick salted butter, softened
1 stick unsalted butter, softened
4 heaping cups sifted powdered sugar
1/4th of a large lemon's juice
1/4 cup Bailey's....or more...let the frosting's consistency be your guide.
Cream together butters, add half the sugar and cream to combine. add the rest of the sugar, lemon juice and salt and combine, then add bailey's and beat until creamy.
