Preheat oven to 350º and line each muffin tin with a cupcake liner. Place one Oreo in each liner.

Beat together cream cheese, sugar, and yogurt until smooth. Mix in vanilla. Add in eggs, one at a time, mixing thoroughly after each.

Spoon cheese mixture into each liner, over the cookie, and then bake for 20 minutes, or until center of each cheesecake is set. Cool and refrigerate for at least 3 hours before serving.
