I have looked around the internet but I cant seem to find the answer, does anyone know how many cake pops a standard 340g bag of candy melts will cover?
It really depends on how thick you coat them, that's why you can't find an exact answer. That and also candy melt bags change size, so a bag of one color may be 340g, another color may be 300g or less. I know Wilton likes to change their bag size frequently so the price on the shelf doesn't change, just the bag size, sneaky.
Best way is to probably buy a bag, weigh a little big out and see how many it coats.
