Preheat oven to 325 degrees F. Paper-line 24 muffin cups. Cut each square in half. Place one piece of dough in each muffin cup.
Bake for 10 to 12 minutes or until cookie has spread to edge of cup.
Beat cream cheese, sweetened condensed milk, eggs and vanilla extract in medium bowl until smooth. Spoon about 3 tablespoons cream cheese mixture over each cookie in cup.
Bake for additional 15 to 18 minutes or until set. Remove from oven to wire rack. While still warm, top cheesecakes with morsels. Morsels will soften but will retain shape. Cool completely. Refrigerate for 1 hour.
