I've went threw my food coloring and I do not have any black. I told my neice I would make her spiderweb cookies to take to school next week for Halloween but I'm not sure how to make black.
This is probably a easy silly question but I have never done it and would rather be safe than sorry. 
Thanks,
Trisha
The best way is to make like a dark brown...then add black to it...quickest way!
The ABSOLUTE best way to get black, without the after taste, is to make chocolate BC and use black to get desired color. It will taste great and you won't have to empty your black food coloring.
There are two ways I make black icing (depends on the flavor of the cake):
1. Use a chocolate b/c and add black - let it set! (My favorite method)
2. Use the darkest brown Americolor available, then add black - let it set! I believe someone else suggested making a very dark brown - it works!
To get a great black w/o the bitterness (also works for red) make your icing a few days ahead of decorating. Do not mix it as dark black as you can when you are making it because it gets darker as it sits and you do not have to add as much of the black (or red) color.
I hope this helps, others may have better ideas for you. Either way, you should find what works best for you. Good luck with your black icing!
