Never found the "perfect" vendor supplied chocolate vape (of those willing to ship to Canada), so I'm still searching out my nirvana via DIY.
Certainly not perfected at this point, but I've found (for me, and that's the tough part with any flavour being so subjective & personal), that it appears that a perfect taste satisfaction "may" be up to a mixture of both dark chocolate (cocoa, double chocolate, chocolate brownie, etc), with a milk chocolate flavouring, and possibly a sweetener ingredient.
Still, I'm so far off of nirvana with finding the right "ratio" of flavours that its not valid posting a recipe that is workable.
Time will tell......
