In a medium saucepan over medium heat, combine milk, cream, molasses, brown sugar, ground ginger, cinnamon, nutmeg, and cloves.
Bring the mixture to a gentle simmer while stirring continuously to ensure even heating and to prevent scorching. Let simmer for 5 minutes. Do not let mixture come to a rapid boil.
Remove saucepan from heat and stir in vanilla extract.

Shake well before using.
