Don't use ready made cake mix its way too expensive.

just get catering bags of plain flour and mix it with cocoa powder about 10:1 (flour to cocoa powder).

It makes the thick brown glop Mel gets dumped over her head

how is that mix to clean up and can you just wash it down the drain

so flour, cacao and what you add to make it runny?

Yes it goes down the drain easily

Just flour cocoa powder and flour mixed with water.

Add the water slowly until you get the right consistency.

Tip - if you make it too thick it won't stick the the "victim's" skin properly it will slide off in lumps

Used some of Freddy's recipie on Fae Taylor today. I was pleased with the results. She perhaps less so

It is brilliant, thanks. I credited you, but forgot your name, so I think I called you Freddy McBlatt from our American branch!

Thanks for the great recipie

No worries Reverndsl glad it worked for you.

Lol its a really gloopy mess for the victim :splat:

It is...and so simple.

Look forward to seeing the results
