Can anyone please tell me how to get a truly black buttercream icing for Halloween? Wilton Black just gives me an ugly grey. I'm afraid I'd have to use the whole jar to get it black, and that would most likely taste bad.

I used chocolate frosting and colored it black. Or you can color it brown and then add black. Also give it time for the color to "mature".

add the black to an icing that is already colored. doesn;t matter what colour. of course if it is blue or any dark colour already that will help. stop adding black when it looks like a dark steel grey. it will deepen once its piped.

I use black cocoa powder and continue adding that until I get the darkness that I want. Just a note of caution adding the black cocoa powder will require you to add some liquid into your frosting otherwise it gets very stiff.

Chefmaster black will give you a true black and it doesn't take very much. You don't have to wait for the color to intensify and there is no bitter taste.

Americolor Super Black is awesome as well!

Thank you all for your suggestions. Perhaps now I can get 'er done.
