The recipe version that I read stated as follows: "Melt cocoa butter. When it's melted, add baking soda, cornstarch, and if a dark chocolate melt is wanted, add cocoa powder. If not, leave as is. After everthing is completely mixed and molds are ready, cool until pot is just warm to the touch, but still liquid." Someone must have added the cocoa powder idea. Please don't take offense Bunny as none was intended.
