Cream the Shortening with an electric mixer until is is fluffy.
Add the powdered sugar, a little bit at a time, mixing well. Add salt, vanilla, and heavy cream and blend until everything is combined.
Now blend on high until frosting is light and fluffy. It took just a few minutes for me.
I used a 1M tip in a piping bag to make the rose effect on the cupcakes.
Fill your Piping Bag with tip with your butter cream Icing.
Start in the center of your cupcake. Start piping your icing and then slowly move your tip in a circle around the center point of the cupcake. Just Keep going around the cupcake until the whole top is covered.
