Have not tried a lot of different icing recipes but this one definitely yummy. Be sure to use clear extract if you want white icing, using regular extract will give it an off white colour.more
stick salted butter - room temperature
stick unsalted butter - room temperature
tablespoon Clear Vanilla extract
pounds confectioner's sugar (powdered sugar, 10x)
tablespoons very cold milk
Cream the butter and shortening in the bowl of an electric or stand mixer. Add the clear vanilla extract and combine well. Begin adding in the sugar and mixing thoroughly after each addition. After all of the sugar has been added and mixed thoroughly, begin adding the very cold milk... one tablespoon at a time, combining very well after each addition (mixer on medium-high to high speed) until you reach the desired consistency.
