Black icing for a penguin birthday cake - how and where?

[fridayschild]

Ds2 believes he is a baby penguin so I thought I would do him a penguin cake, I don't fancy a billion tubes of the supercook stuff, anyone got any other ideas?

Specialist cake shops often sell little tubs of colouring paste which you can add to icing. If I'm using buttercream (which I usually do as I find it easiest!) I also melt a little bit of dark chocolate and add this as the paste never comes out proper black IME and the chocolate helps.

I've got a pack of Super Cook Ready to Roll Coloured Icing. It contains 4 packs of coloured icing - red, yellow, green and black. 125g of each. I bought it in sainsbury's.

Thanks very much, this will make the penguin's day!

I've got an alternative
