It is possible to make cream cheese SMBC but you have to add the SMBC to the cream cheese. Here is the recipe & method that was posted right here on cc http://www.cakecentral.com/b/recipe/jennifer-bratkos-cream-cheese-swiss-meringue-buttercream
Now I want to make this too. Has anyone ever covered it in fondant? Does it hold up well? I'm thinking of using it for a baby shower cake that I'm making for my daughter's best friend. I'm thinking chocolate truffle filling & caramel SMBC.
Is this what you are looking for? http://www.kathryns-cakes.co.uk/patterned_paste_leaflet_1.pdf
