6 cups powdered sugar

1/2 teaspoon salt

1/2 cup boiling water

2 1/2 cups vegetable shortening

6 ounces 1 1/2 sticks dairy free margarine

1 tablespoon gluten-free coconut extract

In the bowl of an electric mixer, combine powdered sugar and salt.

With whisk attachment, add boiling water and whip at medium speed until smooth and cool, approximately 5 mins.

Remove whisk attachment and replace with paddle attachment.  Add shortening and margarine to mixing bowl and beat on medium speed until smooth, approximately 3 mins.  Increase speed to medium high and whip until light and fluffy and increased in volume, about 10 mins.

For vanilla buttercream frosting, replace coconut extract with an equal amount of vanilla extract.
