Combine all ingredients in a pot and warm over medium to medium high heat. Stir constantly with a whisk.
Pour into cups and serve.
Using Real Chocolate
If you prefer a richer hot chocolate, chop up about 1 cup of unsweetened baking chocolate.
Melt in the microwave in 30 second intervals, stirring after each interval, until it's fully melted.
During these intervals, combine all the other ingredients in a saucepot and warm. Do NOT let the milk boil or scald. You want it hot, but not burnt.
When the chocolate is fully melted, scrape it out of the bowl into the hot milk, turn off the heat under the pot and whisk quickly to combine.
Adjust sweetness to taste.
Pour into cups and serve.
