Beat the confectioners' sugar, peanut butter, melted butter, vanilla extract and salt with an electric mixer until well combined. Roll rounded teaspoons of the mixture into round balls and place on a parchment-lined baking sheet.
Roll the peanut butter balls in any or all of the possible truffle accompaniments. Chill until firm, about 20 minutes. These truffles are best served very chilled.
