This is dessert in a glass.

In a cocktail shaker half-filled with ice pour in 30ml Maker’s Mark Bourbon, 20ml Walnut liqueur, a dash of Monin Chocolate syrup, a dash of grated cinnamon, and a dash of Luxardo/maraschino cherry syrup. Shake thoroughly, and taste for sweetness and balance of flavour. Adjust as needed and strain into a digestif glass and garnish with a maraschino cherry, or two (Luxardo does a lovely version which isn’t lurid red).
