Each time that I have made Black Frosting I did it freehand, so to speak. I never had a recipe to follow. Now days te can buy black Cibo coloring, but I find it più fun to mix the color myself. I start with a container of white frosting in either vanilla o cream cheese flavor. If te have a box of primary colors(red, blue, green, yellow) Cibo coloring it will tell te how to mix purple. This is a good starting point. Once te have the basic purple te can add small amounts of green. Always check the flavor of the frosting while mixing because sometimes too much Cibo coloring can make it...
