Ok, so I made my first castle cake in June - turned out ok - I was happy. Now dgs wants a black castle/dungeon cake.

My question is can I turn ganache black with regular wilton colors? TIA.

Hi. I'm sorry to say but no wilton colors (candy) are only for candy melt use which is not a real choc. If you add the color to the ganache it will seize and become useless. Your best bet is to use bittersweet choc because it is the darkest. Choc can also be airbrushed with cocoa butter mixed with powdered color but this is expensive and would require waiting for shipping and all that. You could try to mix powdered black coloring into your ganache and keep your fingers crossed. It might work but I've never tried it because choc. is just too $$$$ to throw away. hth and good luck

Thanks so much. I guess I'll just go with chocolate buttercream.
