Artist Marc Brownlow won first place in the food category of our Halloween contest last year for his gorgeously gourmet Skull Truffles. His how-to is a clear and well-photographed 19 steps, and the end result provides some delicious motivation: dark chocolate center, white chocolate skull, with candied walnut braaaaaains!

But the part that folks found challenging was making the skull molds. Marc is a product designer, graphic designer, and illustrator, which explains why his skull molds look so darn good. I can guarantee my version would look more like snowman heads than skulls. Here’s Marc’s version:

Several folks had asked if Marc would make and sell the molds. I touched base with him to get his thoughts and he wrote:

I’m delighted that people still like that project. I would be willing to sell the molds, but the price of just the food-grade silicone alone is so high ($25/lb) that I don’t know if people would want to pay for it. By the time I added shipping and paid myself anything for labor it would be in the $30-$35 range. My instinct is that if it was around $10 per finished mold, people might go for it, but I don’t know where I could get super cheap food-grade silicone.

I made a big batch of skull truffles for a party on Saturday and they were a big hit. I treated myself to a chocolate tempering machine last year and it makes the process so much quicker. I also made candied walnut brains instead of using candy melts, since the candy melt had too many artificial ingredients for my tastes.

I would be willing to look into what was required to sell the skull truffles themselves. I suspect I’d need to get a food safety license and learn how to safely ship chocolate so it doesn’t arrive in a melted puddle.

Anyone know of a source for super cheap food-grade silicone?
Alternately, anyone got tips on shaping skulls? Post up in the comments below!

I’m senior editor at MAKE and have worked on MAKE magazine since the first issue. I’m a word nerd who particularly loves to geek out on how emerging technology affects the lexicon as a whole. When not fawning over perfect word choices, I can be found on the nearest mountain, looking for the ideal alpine lake or hunting for snow to feed my inner snowboard addict.

The maker movement provides me with endless inspiration, and I love shining light on the incredible makers in our community. The specific beat I cover is art, and I’m a huge proponent of STEAM (as opposed to STEM). After all, the first thing most of us ever made was art.

  1. Maybe he should consider selling copies of his original pieces he cast the silicone molds from. I imagine they would be cheaper and folks could make multiple silicone molds from them to speed their production. Just a thought, might not be feasible either.

      That’s a good suggestion!

    We need a 3D chocolate printer!!

  3. Kelly says:

    So freaking awesome.

  4. I am sure you can get Halloween skull shot glasses easily and use that as a mould but then it be a pain to get the chocolate out afterwards..

  5. Too good! Excellent use of a nut.
