I make cocoa by heating up some soymilk in the microwave for a minute, then I add a couple spoonfuls of unsweetened cocoa powder, stir in a spoonful of maple syrup (or turbinado, both work) and heat it up again for 30 seconds.
For flavor variations I add:
-sprinkle of cinnamon
-Orange Chocolate: orange extract
-Mint Chocolate: mint extract
-Pumpkin pie: cinnamon, nutmeg, cloves, allspice
-Gingerbread: cinnamon, nutmeg, allspice, cloves, ginger and a bit of molasses
