Add cognac, crème de cacao, and heavy cream into a cocktail shaker.
Fill the shaker two-thirds with ice.
Shake vigorously for 12–15 seconds until well chilled and fully emulsified.
Double-strain into a chilled cocktail coupe or Nick & Nora glass.
Garnish with a light grating of fresh nutmeg over the surface and serve immediately.
Dark crème de cacao is the traditional and preferred choice here - it delivers deeper chocolate intensity than the white variant, giving the drink its characteristic richness and color. Some bartenders swap equal parts cognac for a split of cognac and aged rum to add subtle complexity without straying far from the classic.
