Hi, I've been having trouble with my cream cheese icing recipe? it's thin even if I add powdered sugar and too sweet. Does anyone have any tips or recipes they could share?

Instead of cr ch make your regular buttercream adding either cr ch flavoring or white balsamic vinegar

That is the nature of cream cheese frosting.  It is much softer than buttercream and is not as stable.  As kakeladi said, you can either use Lorann Cream Cheese flavoring in buttercream to get the cream cheese flavor (I use this a lot and it is delicious) or try -K8memphis recipe for buttercream flavored with white blasamic vinegar, which is also delicious and similar in taste to cream cheese frosting.
