In a large mixing bowl, beat the cream cheese until smooth.
Add the pudding mix, sweetened condensed milk and 3 cups regular milk and continue beating until smooth and well combined.
Beat in thawed large Cool Whip.
Fold in bananas and 1 box of cookies.
Pour into a large serving bowl, top with a small container of cool whip and garnish with additional cookies.
Cover and chill until ready to serve.
Notes
I like to make this the day before and let it chill in the refrigerator overnight. The flavors taste much better and the cookies soften and become cake-like.
