In a large bowl, combine the creamy peanut butter, graham cracker crumbs, powdered sugar, and melted butter. Mix until well combined and the mixture holds together.
Shape the mixture into small balls, about 1 inch in diameter. Place them on a lined baking sheet and chill in the refrigerator for 15 minutes.
In a microwave-safe bowl, melt the chocolate chips and vegetable oil together in 30-second intervals, stirring in between, until smooth and melted.
Using a fork or toothpick, dip each chilled peanut butter ball into the melted chocolate, allowing any excess to drip off. Place the coated ball back on the baking sheet.
Repeat the dipping process for the remaining peanut butter balls.
Chill the coated balls in the refrigerator for another 15 minutes or until the chocolate is set.
Serve and enjoy!
