in a cup, combine all the dry ingredients. I add cornstarch to thicken the hot chocolate a bit, and although it is optional, I totally recommend it! The more you add, the thicker the hot chocolate will become. Be careful not to overdo it, though, for you will end with a pudding of sorts! And stir constantly to prevent lumps from forming.
pour milk, and stir. Pour into a pot and heat until it boils. Keep stirring until it thickens a little bit.
serve and enjoy!
