Add marshmallows to a medium microwave safe bowl. Pour water over top. Microwave for 90 seconds. Stir until all marshmallows are melted. Set aside to cool.
Prepare pudding as directed on the box, using milk. Chop graham crackers into bite size pieces.
Add 1 tablespoon Nutella to 4 individual trifle dishes, or more if you so desire. Add ¼ of graham crackers to each dish. Pour ¼ marshmallow mixture over graham crackers in each trifle. Sprinkle with 2 tablespoons chocolate chips. Add ¼ of pudding to and smooth over top. Add a dollop of whipped cream. Drizzle with chocolate syrup. Serve and enjoy!
Notes
These will keep in the refrigerator for several days and make a great make ahead treat. Also, I like to make little trifle shots (serves 12) for a little taste of something sweet.
