I am looking for a cream cheese frosting that is stiff enough to decorate with. The recipe I have is yummy but, too soft.

Try the crusting cream cheese recipe from this site. It decorates well!

The 'decorators cream cheese' frosting is the one I use and love!

Here are all the CC cream cheese frosting recipes:
