In a large mixing bowl, beat softened cream cheese and peanut butter together until completely smooth.
Gradually add powdered sugar and vanilla extract, mixing until a firm dough forms.
Roll the mixture into 1-inch spheres and place them on a baking sheet lined with parchment paper.
Place the tray in the freezer for 30 minutes to firm the centers.
Melt the chocolate chips and coconut oil in a microwave-safe bowl in 30-second increments, stirring until smooth.
Using a fork or dipping tool, coat each ball in the melted chocolate and return to the parchment paper.
Refrigerate for at least 15 minutes until the chocolate shell is fully set.
