I've never had a real cappuccino, but I do like coffee with extras. I've tried Capella and Flavour Art cappuccino flavors, and wasn't very happy with them. I do like most of the other flavors that I got from those brands, though.
I'm another who likes TFA caramel cappuccino. Not being a fan of black coffee, I doctor it with TFA Bavarian cream and EM. My latest, favorite recipe for it is pretty simple:
For 10ml batch:
1 drop TFA Caramel Cappuccino
7 drops TFA Bavarian Cream
3 drops TFA Ethyl Maltol
Sometimes I add a drop or two of cinnamon flavoring.
