°3 packages instant French vanilla pudding
°5 cups of milk
°8 ounces of sour cream
°1 container of Cool Whip
°1 box vanilla wafers
°6 bananas

* Methods 

Using a blender, combine the 3 packages of pudding and the 5 cups of milk. Mix until thickened (about 2 minutes).
Add sour cream and mix. Stir in Cool Whip. (I also use the mixer for this part.)
Line a large baking dish (I use a 9x13 glass pan) with vanilla wafers, then bananas and half the pudding mixture. Repeat layer of wafers, bananas and remaining pudding mixture. I like to crumble vanilla wafers on top to finish it off.

Enjoy !
