In a large bowl with either a hand or stand mixer, beat softened butter with peanut butter until fluffy. Gradually add in powdered sugar 1/2 cup at a time until a thick dough forms.
Roll the peanut butter dough into small balls and place onto plates. Refrigerate for at least 30 minutes. Melt candy melts according to package directions. Stirring after each interval until fully melted and smooth.
Dip each peanut butter ball into the melted chocolate to coat it fully. Place the peanut butter balls back onto plates and refrigerate for another 30 minutes, or until set.
