In a medium mixing bowl, beat cream cheese together until smooth and creamy, approximately 2-3 minutes.
In a small mixing bowl, beat banana pudding mix, vanilla and evaporated milk together until thick and creamy.
Add banana pudding to cream cheese and beat until well combined.
Once cake has cooled, add half the pudding mixture into a quart size freezer bag and clip the corner.
Squeeze banana filling into each hole then spread remaining pudding mixture over the top of the cake.
Spread cool whip over the top of pudding, cover with plastic wrap, place in fridge to chill.
Once chilled, sprinkle vanilla wafers over the top and add sliced bananas.
Enjoy!!
