Preheat the oven to 275 degrees Fahrenheit. Line a 12-cup muffin tin with cupcake liners. Place a piece of Oreo cookie in each liner.
Beat the cream cheese at medium speed until fluffy.
Add the sour cream, sugar, and vanilla extract, and eggs, beating after every addition.
Mix in the chopped Oreos with a spatula until combined.
Spoon the cheesecake batter into the muffin tin ¾ full.
Bake for 20 to 22 minutes. Transfer the cups onto a wire rack to cool. Refrigerate for 4 hours or until firm.
Serve, and enjoy!
