TO MAKE MINI CHEESECAKES:
Spray regular-size cupcake liners with baking spray. Place an Oreo cookie in the bottom of each liner. Divide batter into liners until they are filled to about 1/4-inch from the top. Sprinkle with mini chocolate chips and bake 20 minutes, or until tops spring back when lightly touched in the center.
For best distribution of chips throughout the cheesecake, do not overbeat the cream cheese.
