1In a medium bowl, mix together the peanut butter and powdered sugar until well combined and smooth.
Roll the mixture into small balls, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
In a microwave-safe bowl, combine the chocolate chips and butter. Microwave in 30-second intervals, stirring in between, until the chocolate is completely melted and smooth.
Using a fork or a toothpick, dip each peanut butter ball into the melted chocolate, ensuring it is fully coated.
Place the chocolate-coated balls back onto the parchment-lined baking sheet.
Refrigerate the chocolate peanut butter balls for at least 30 minutes, or until the chocolate has set.
Serve and enjoy your delicious Chocolate Peanut Butter Balls!
