This wasn't my idea; a friend gave me her recipe and I just adjusted it to my own tastes. But it's become a regular vape for me and thought I'd share it. This recipe is for flavoring only. 
This will make 30 ml of flavoring, but I put in the percents to give a handle for mixing other sized batches.
Tiramisu Coffee
TW Tiramisu -- 66% -- 19.8 ml
Perfumer's Apprentice Chocolate -- 24% -- 7.2 ml
Flavour Art Mellow Sunset tobacco -- 10% -- 3 ml
Lorann's Coffee -- 5 drops (maybe one drop per 6 ml or so; this stuff is almost too potent)
That's it; home some of you like it.
