In a small bowl, beat together, using med speed on hand mixer, the sweetened condensed milk and water until well combined (about 1 minute). Add the pudding mix and mix well (about 2 minutes more).

Cover and refrigerate for 3-4 hours or overnight.

In a large bowl, on med. speed of hand mixer, whip the heavy cream until stiff peaks form.

Gently fold the pudding mixture into the whipped cream until well blended.

To assemble:

Use a large clear glass bowl with a 4-5 qt capacity.

Arrange 1/3 of the wafer cookies to cover the bottom of the bowl, then layer bananas, then pudding.

Repeat the layering two more times, ending with pudding.

Crush a few wafer cookies and sprinkle on top.

Cover with plastic wrap and refrigerate for 4-8 hours (no longer).

Enjoy!
