You can whip up this satisfying drink in minutes -- who says you can't have a white hot chocolate?
Heat milk and vanilla bean in pan over medium heat until almost boiling. Remove from heat. Remove vanilla bean halves; scrape seeds into milk. Stir, then let stand, covered, to infuse, 5 to 10 minutes.
Place pan over medium-low heat; add white chocolate; whisk until completely melted. Serve immediately in mugs.
