In a medium saucepan, heat 1 1/2 cups water until almost boiling. Turn off the heat and add in the chocolate. Whisk until melted and combined.
Turn the heat back on again if you wish to further melt, heat and thicken. However, do not walk away, chocolate burns very easily. Continue stirring until you remove it from the heat. Do not let the chocolate and water come to a full boil. After the water and chocolate are combined, add in the agave, chile powder and vanilla.
Cook's Note: Some people prefer their chocolate sweeter or even with no sweetener whatsoever. Add in as much or as little as you like. The same goes for the chile powder; some people prefer more spice than others so please adjust for your personal tastes. Enjoy immediately while it's hot, or pour over ice for a unique experience!
