Mix condensed milk, pudding, water and vodka together. Chill for approximately 5 minutes. Fold in the whipped cream. Next layer in serving dish vanilla wafers, pudding, bananas. Repeat layers till bowl is filled. (I did 3 layers). Finish off with the pudding on top. Chill for a couple of hours and serve with additional whipped cream if desired.
For stronger pudding mix switch out equal amounts of vodka for water. You can also use the flavored whipped cream.
