I'm trying to do a glow in the dark cake for my niece.  She wants it black and to have the splatter paint effect in many glowing colors.  Is this possible?  All I've found online is how to make the lime jello with the greenish color.  All help is greatly appreciated!!!!! Happy Baking

I did a glow-in-the dark cake a few years ago using "Tonic Water" to make it glow.  Did you see this idea/technique when doing research?  I messaged the customer after the party to see how it went and they said it worked.  She said the party was outside and it wasn't quite dark yet when they put it under the blacklight, so it did glow but not super bright (it may have done better in a totally dark room with black lights - but we will never know).  They were very happy with the results! 

Tonic water is supposed to make it glow when under a black light. I've never tried it but I think it would work. Hope this helps!

Thank y'all very much!  We've changed up what she wants again so, this should be interesting
