Melt together cacao butter, coconut butter, coconut oil, sweetener, and salt over a double boiler (or a metal bowl on top of a pot of boiling water). Once everything is melted, stir in cacao powder and vanilla. Stir vigorously to combine. Pour into a standard bread pan lined with parchment paper and set in the refrigerator. Slice into cubes, dust with cacao and enjoy! Store in refrigerator for weeks, or freezer for months.
