Crush Oreo cookies in a food processor until fine crumbs form.
Transfer crumbs to a mixing bowl and combine with softened cream cheese.
Mix until well combined and a dough forms.
Roll the mixture into 1-inch balls and place on a baking sheet.
Freeze the balls for at least 10 minutes to firm up.
In a microwave-safe bowl, melt the chocolate chips with vegetable oil, stirring until smooth.
Dip each ball into the melted chocolate, ensuring it is fully coated.
Place the chocolate-covered balls back on the baking sheet.
If desired, sprinkle crushed Oreos on top before the chocolate sets.
Refrigerate for about 30 minutes to allow the chocolate to harden.
