In a small pot, mix powders and sugar and pour just a little bit of milk. Mix all ingredients with a wooden spoon, until all lumps have dissolved. Pour the rest of the milk and mix well.
Place pot on stove over medium heat and keep stirring. Remove pot from the heat when chocolate has reached the density you desire. The more you cook it, the denser the hot chocolate will be. I like my hot chocolate a bit dense...but not too thick!
