Reese’s — the peanut butter cups and most products — contain no pork, gelatin or alcohol, so they are halal by ingredient: chocolate, peanuts, sugar, milk and emulsifiers. They land on "depends" because there is no US halal certification and the emulsifier (such as PGPR) and whey sources are not independently verified. Most scholars accept Reese’s as halal by ingredient; a certificate would remove any doubt.

The short version
Reese's peanut butter cups and most products contain no pork, gelatin or alcohol, so they are halal by ingredient. They are simply uncertified in the US.
What's in them
Reese's are milk chocolate, peanuts, sugar, dextrose, salt and emulsifiers (such as PGPR and lecithin). There is no gelatin and no pork.
Why "depends"
There is no US halal certificate, and a couple of ingredients — the PGPR emulsifier and the whey — are not independently verified as to source, though neither is flagged as animal-problematic. So Reese's are best described as halal by ingredient, uncertified, which most scholars accept.
