Start with 2 cups of dark chocolate chips, add 6 cups of milk, 1 cup of heavy cream, a can of condensed milk...
1/3 cup cocoa powder, and some vanilla and salt. Stir it together, cover your Crock-Pot, turn it to Low, cook it for about 2 hours...
At the end just give it a good whisk so everything's melted and smooth. You can serve this with marshmallows
I really love it with some whipped cream and a lot of chocolate shavings on top. Enjoy, and stay warm!
