Boil water and place in glass or metal mixing bowl
In smaller bowl, combine cacao butter and vanilla. Place small bowl in mixing bowl with water and use as a “double broiler”
Be careful not to splash water into cacao butter mixture or it will seize (you’ll know that it’s seized when the chocolate gets hard and will not melt no matter how hot you get it. I now have 5 sets of chocolate fudge because of seizing :| )
Continue to stir cacao butter until melted. Remove from water and add cacao powder
Continue to stir until mixed
