Does Cream Cheese Icing need to be refrigerated? I am making a full sheet cake and I do not think it will fit in the refrigerator. Here is the recipe. The cake will be picked up on Friday morning for a Saturday wedding.
1/2 softened cup butter
1 8 oz. pkg. softened creme cheese
1 tsp. salt
1 tsp. vanilla
Cream butter and creme cheese. Add powdered sugar.
Beat until fluffy. Add salt and vanilla into the icing.
Thanks!!
You really need to keep cream cheese icing refrigerated.
Not all cream cheese frosting requires refrigeration; it depends on the proportion of fat and sugar to the perishable ingredient.
Here's a cream cheese frosting that doesn't require refrigeration:

Here's a handy chart on how to safely store frostings and fillings:

You're very welcome, mdutcher. 
Was pleased when I came across this info as the question comes up frequently. And no one wants to make their customers or loved ones sick by chancing a perishable filling or frosting...
Guess this falls under "Better Living through Chemistry".
You can also flavor your favorite frosting (shelf stable) with cream cheese extract for another option.
