In a large bowl, mix crushed vanilla wafers, powdered sugar, peanut butter, and melted butter until well combined.
Shape the mixture into small balls, placing them on a wax-paper-lined baking sheet.
Chill balls in the refrigerator for 30 minutes.
Melt chocolate chips in a microwave-safe bowl, stirring every 30 seconds until smooth.
Dip each ball in melted chocolate and place back on the wax paper to set.
