Every time I make cream cheese icing for a carrot cake and follow the instructions (icing sugar, orange juice and philadelphia, basically) it goes slimy and sloppy, and doesn't stay put on the cake.
I need something that goes on nicely and forms a slight crust after a while. Even when I've added butter to the icing, it's still on the sloppy side. Any tips? (I want to flavour it with lime or orange, so need to add zest and a bit of fresh-squeezed juice.)
