All four ingredients are stocked at every major Charlotte grocery chain, and vanilla ice cream, Guinness, and Baileys are staple products carried even by ALDI and Food Lion. The cost per serving runs about $3 to $3.50—the Baileys and Guinness are the drivers, but neither requires a premium purchase or a large bottle for just two servings. The stated time is honest; this is truly a five-minute assembly. The main drawback is that it is emphatically a same-night dessert: ice cream melts, foam collapses, and reheating this concoction the next day yields only regret. For a weeknight treat for two, though, it's cheap, available, and requires zero real cooking.
