(Magnolia Bakery) Banana Pudding

1 1/2 cups cold water
1 (14oz) can sweetened condensed milk
2/3 cup instant vanilla pudding powder
3 cups heavy cream
One box Nilla wafers
3 to 4 medium banana, sliced

With an electric mixer, blend the water, millk, and pudding powder until
thoroughly mixed, about 1 minute. Refrigerate for at least 4 hours or
overnight until firm. In a seperate bowl, whip the heavy cream until soft
peaks form. (that means if you pull the beater out of the cream, it will
hold the shape.) Gently fold the pudding mixture into the whipped cream
until well incorporated. In a large bowl, starting with the wafers, make
five to six layers with Nilla wafers, sliced bananas, and then pudding
mixture, until all of the pudding mixture is gone. End with pudding and
decorate with crushed wafers on top if desired. Refrigerate about 30
minutes before serving and refrigerate any leftovers. Serves 10-12
