Decorator’s Icing

When I was a kid, my mother used to decorate cakes for others.  I loved her cakes.  This is her icing recipe that I grew up licking off the beater.  I use this icing on cakes and cookies. 

Mom’s Icing (aka Decorator’s Icing)

2 lb bag powdered sugar, sifted
1 cup shortening
1 teaspoon clear vanilla
1/8 teaspoon butter flavoring
1/2 cup water or more

Cream shortening with mixer until smooth.  Add powdered sugar 1/2 cup at a time while the mixer is on lowest setting.  Add water as the mixture stiffens.  Add vanilla and butter flavorings.  Once all the powdered sugar is incorporated add water to reach desired consistency.  Ideally the icing should be smooth and creamy but maintain its shape.
