The best hot chocolate EVER

I love hot chocolate.  Until recently, Starbucks hot chocolate was my favorite. That changed with this recipe.  I am a big fan of rich, sweet hot chocolate.  Starbucks is rich, but not terribly sweet.  This stuff is amazing.  Everyone loved it. John, who can't handle rich foods, drank a little, loved it, and then had to wait a little while before he could handle having more!  If you prefer the richness without sweet, you can use 2 cups of heavy cream in the place of the sweetened condensed milk.

6 cups milk
2 cups milk chocolate chips
1 tsp. vanilla
1 can sweetened condensed milk

Combine all ingredients in the crock pot. Cook on low for 2 hours, stirring occasionally.  Top with marshmallows or whipped cream. (Doesn't need either one, but it they are fun for the kids.)
