This is a nice icing
that is very smooth and perfect as a
frosting.
It remains soft and is easily
pipedFor
best results, keep icing covered with a damp cloth in refrigerator when not
being used.
Cream butter, shortening, sugar and vanilla.
Stir cornstarch into milk and add gradually to sugar mixture, beating all the
while. Beat at low speed until blended. Beat at medium speed 5-7 minutes
until icing is creamy smooth. (personal note -- it may look funny when you stop
blending, wait 20 minutes and beat again! The cornstarch may need time to
thicken!)
