-1 1/2 cups soy or other non-dairy milk
-2 tbsp cocoa powder
-4 tbsp sugar
-1 tbsp corn syrup (agave may work here, I'm too poor to use it)
-1 tbsp vanilla extract
-pinch of salt
-pinch of cinnamon
Add everything but soymilk to a mug. Pour just enough milk to cover the ingredients, and mix together until most clumps are gone. Microwave on high for 40 seconds. Stir until most remaining clumps are gone, and then add the rest of the milk. Microwave for 1 min on high, then stir, repeat until it is warm enough.
I say a cup and a half of soymilk because that's aproximately what my dollar store mugs hold, and I make my hot chocolate for those mugs, heh.
