Mix together your simple syrup! Combine your cocoa, sugar, and water and heat (in the microwave or on the stove) until hot. I just heat it in the microwave (approx 45 secs), it is the quickest and less messing up dishes way.
Once your syrup is heated through pour in your milk and heat again. I heat this step for approximately 1:30 - 2:00 minutes.
Stir in vanilla extract and enjoy! This is enough for a large cup or 2 smaller cups.
