Step 1

In a large bowl, whisk together condensed milk and cold water. Pour the vanilla pudding mix and beat at medium speed for 2 minutes or until well-combined. Chill in the fridge for 5 minutes. Gently mix in the heavy cream with a rubber spatula.

Step 2

Arrange 1/3 of the vanilla wafers into a single layer in a large trifle bowl or glass. Slice one banana thinly and layer it on top of the wafers. Top it with 1/3 of the pudding layer. Repeat layering twice more, ending with the pudding.

Step 3

Chill the dessert for 1 hour. Sprinkle with fruits or nuts, if desired. Serve and enjoy!
