"Melted Brownie" hot chocolate

This is absolutely the most delicious hot chocolate I've ever had! It tastes just like a melted fudge brownie. I would say it equals in lusciousness to Starbucks' hot chocolate, which tastes like a melted chocolate bar. A friend of mine served this last week at her house. Yummy yummy! Make sure to serve it with lots of whipped cream on top.

1 cup milk
1 cup half & half
8 tsp sugar
1/2 tsp vanilla
1 oz semisweet chocolate, chopped
1 oz unsweetened chocolate, chopped

Heat milk, half & half, both chocolates, and sugar in a saucepan on medium-low heat until chocolates melt and sugar dissolves. Pour half of the mixture into a blender and mix until frothy. Return to saucepan and add vanilla. Stir briefly and serve.
