Ingredients needed: sugar, flour, unsweetened coco powder, Milk, Butter and Vanilla.
Fill a medium Sauce pan about a quarter full with milk over medium heat, throw a chunk of butter in there, with a splash of vanilla (proceed with caution, vanilla is strong), Wait for the butter to melt, it will make it blend easier with the dry ingredients. which you should proceed to put that in the pan next. Putting the heat now to medium-high, mix and let simmer/bubble for 6 minutes, then turn off the heat! Would recommend putting a shake or two of Salt in the sauce, brings the chocolate flavor out more! Voila your done, enjoy!
