Combine cold brew coffee, vodka, Irish cream liqueur, and coffee liqueur in a cocktail shaker.
Add ice and shake vigorously for 10–12 seconds.
Fine strain into an ice-filled Old Fashioned glass.
Serve without garnish.
Fine straining is key here - it removes ice chips that would otherwise dilute the creamy texture and dull the cold brew's intensity. Chilling the glass beforehand helps maintain that dense, velvety mouthfeel.
