We ate this for the first time at a BBQ place in Stephenville, TX and fell in love with it!! So, I was determined to come home and figure out how to make it...found this recipe on another website and it was identical to the one at the BBQ place :)I usually make a double recipe so it makes a large bowl.
Combine sweetened condensed milk and cold water in large mixing bowl, add dry pudding mix and beat on medium speed for 3 mins or until smooth and then chill for a few mins.
Whip heavy cream into stiff peaks and then fold cream into pudding mixture.
In a large glass bowl, spread 1/2 cup of pudding on bottom of dish (or enough to cover the bottom)and top with a layer of vanilla wafers, followed by layer of bananas and then a pretty thick layer of pudding. Continue with layers, finishing with pudding on top. To crush wafers for the topping, I used a large zip lock bag and crush enough to cover top of pudding and your desired thickness of crushed wafers. Chill for 5 hrs and enjoy!
