Triple Chocolate Marshmallow Milkshake

Whisk 1/2 cup heavy cream, very cold marshmallow fluff and vanilla until stiff peaks form; set aside.

Combine whole milk and cup chocolate syrup in a blender. Add 3 cups chocolate ice cream; blend until smooth.

Fill 4 glasses one-quarter of the way with the shake; add some marshmallow mixture, then more milkshake, then cream, then milkshake.

Finish with a dollop of marshmallow cream and garnish with shaved chocolate.
