In a stand mixer (or mixing bowl) combine cream cheese, butter and shortening. Mix on low until creamy and fluffy about 3 minutes.

Mix in vanilla, salt and powdered sugar one cup at a time until completely incorporated.

Mix in the milk a tablespoon at a time if needed to get the consistency you like. I used only 2 tablespoons of the milk for a stiff consistency to pipe with and 3 or more tablespoons for a more spreadable consistency. Just make sure to add a little bit at a time then mix as you go before adding more all at once. If your frosting is too runny then add more powdered sugar, a little at a time.

This is a great recipe for piping decorations on cakes & cupcakes because once it dries or is in the fridge for a bit it kind of crusts up and doesn't melt on ya!

Makes enough frosting to frost 2-9" round cakes.
