Whats the costco birthday cake icing recipe?

Does anyone know how to make the icing from the costco birthday cakes they make? I absolutely love it xWhats the costco birthday cake icing recipe?
i don't know, but here are some good ones:





Quick and Easy Powdered Sugar Icing





2 cups powdered sugar (sifted)


1/2 teaspoon vanilla


2 tablespoons milk








Mix the powdered sugar with the vanilla and milk. Then add more milk a bit at a time until it is thin enough to drizzle over a cake. Once you've iced your cake, it's best to let it stand for one or two hours.








To make chocolate icing, add two tablespoons cocoa powder when you mix the powdered sugar and follow the rest of the recipe above.





Thick Vanilla Frosting








1 cup shortening


2 teaspoons vanilla


4 cups powdered sugar (sifted)


4 tablespoons milk








Beat together shortening and vanilla for 30 seconds medium speed with an electric mixer. Add 2 cups of powdered sugar a bit at a time while beating. Then add 2 tablespoons milk. Slowly add in the rest of the powdered sugar and the rest of the milk until you get the right thickness for your frosting.

oh, and instead of Vanilla, just use choco if you prefer.
