yeah diyflavorshack do a sweet coffee, so does mstsbakery (inc cream), theres a few, but while most are nice, I have never found a 'perfect' coffee with cream flavor and I have a feeling its just not out there. It might really hard to satisfy everyones idea of what it should taste like, a bit like choc flavor, so if I find one great but Im no longer searching for it actively.
I do love VSVapor's Cafe Sumatra - that ones like a sweet syrupy type coffee (like turkish coffee that you get in the tiny cups + sugar) with a hint of..idk..alcohol or something - its really nice though but its not one with cream in it.
