1. Spray a dish and press thawed cookie dough onto the bottom.
2. Bake about 20 minutes at 350 degrees Fahrenheit, or until the cookie is just barely done (soft, not crispy).
3. Beat cream cheese, powdered sugar, and vanilla until smooth. Fold in half of the cool whip and 1/2 cup of mini chocolate chips. Spread onto the completely cooled cookie layer.
4. Mix together pudding mix with cold milk until thickened. Spread onto the cream cheese layer.
5. Spread on the remaining cool whip and top with chocolate chips. Cover and refrigerate overnight. Serve chilled!
