In a cocktail shaker add Tullamore Dew Irish Whiskey, dark chocolate sauce, heavy cream, a pinch of apple pie spice. Top with ice.

Secure the lid on the cocktail shaker and shake for 30 seconds.

Strain into a standard whiskey glass filled with crushed ice if you want it served cold. Otherwise, pour into a saucepan and heat on medium low until warm.

Garnish with a couple toasted marshmallows on a cocktail stick.
