Magnolia's banana pudding!

While in NYC we visited the famous Magnolia Bakery and really enjoyed their banana pudding (sometimes even more than their cupcakes!) and had to look for this recipe and make it when back in Australia. Although we could not find the specific biscuit they call for in their recipe, we made changes and used the ingredients below and it worked quite well :)
F, Mr. F and I really love this!

INGREDIENTS:
1 can condensed milk
1.5 cups of ice cold water
1 box or bag of vanilla pudding (in our case we used a bag of vanilla "Pudding Magic")
750 ml of heavy cream
Lady Finger biscuits
About 6-8 bananas cut in slices.

1. Mix the water and the condensed milk until well combined. Add the pudding and allow to set (this can be made and left overnight). Make sure it has had enough time to set completely.
2. Whip the heavy cream until stiff peaks form.
3. Start softening the pudding mix with a fork and then fold it in the whipped cream gently until they are combined and you can no longer see lumps or streaks of yellow pudding.
4. To assemble: put a thiner layer of cream at the bottom to start, then the sliced bananas and then the biscuits and repeat making thicker layers of cream until the last layer is cream and then decorate the top with some banana slices.

Delicious and easy!
