I wish I could tell you who makes a good peanut butter cup flavor, but I CAN tell you who makes a disappointing one. I tried the peanut butter cup flavor from Rockstar Vapor and was kind of a let down. The juice DID taste like peanut butter cups, but there was also a very strong alcohol taste to it also and no amount of steeping with the bottle's lid removed seemed to make the alcohol taste go away. The juice also had a vague chemical overtone to it...
