Rich Hot Chocolate

Heat milk in a saucepan over medium heat until steam rises from the surface.

Whisk in chocolate and sugar, and continue whisking for 1 to 2 minutes, until sugar has dissolved.

Whisk in vanilla.

Reduce heat to low; keep warm until ready to serve.

Serve in small cups.

For an airier consistency, remove from heat, and mix with a hand blender set on low just before serving
