Crockpot Hot Chocolate

1 1/2 cups heavy whipping cream
14oz can sweeten condensed milk
6 cups milk
1 tsp vanilla
2 cups chocolate chips (I've used milk chocolate and semi sweet..both are great)

Add all the ingredients to the crockpot and stir.  Cover the crockpot and cook on low for 2 hours, stirring occasionally.  It's ready when the chocolate chips are melted and it's hot enough for your liking.  Stir before serving.
