3D Printed Cookie Molds for the Best Speculoos

Experiencing nostalgia for the outstanding Belgian cuisine [Adam], currently stuck in Ohio, found himself in craving some home-made speculoos. For the uninitiated, speculoos is what those brown cookies usually served with coffee on planes dream of becoming one day.

To add some extra regional flavour, [Adam] decided to print his own molds featuring motifs from Brussels. The risks of 3D prints in the kitchen are the subject of a lively discussion. They are addressed in this project by recommending the use of food safe filament and sealant for the molds. The fact that the dough will be removed from the molds almost instantly and that the molds don’t go into the oven puts the risks in the vicinity of using plastic cutting boards in your kitchen.

[Adam]’s write up features solid, well illustrated baking instructions that should enable any of you to replicate this delicacy. Some links to additional references and two recipes are thrown in for good measure. The article finishes with detailed instructions for designing your own molds that take the properties of the medium into account, to ensure your custom motif will still be recognizable after baking. Line art with a stroke width of around 2-3 mm seems to work best. It is that time of year and we hope to see a lot more tricks to take your cookie and edible house designs to the next level so don’t forget to send in a tip.

With 3D printed molds having been used to shape resin, silicone and even metal, we are at a point where cookie dough looks like a natural progression.

  1. Yeah, “food safe filament” DOES NOT MEAN YOUR 3D PRINT IS FOOD SAFE.

    Is your bowdoin tube clean?

    Are you sure your extruder’s feed mechanism uses food-safe lubricants? Does it contain any debris from the mechanism or other filament? Are all the materials safe, and lead-free?

    Does your extruder head contain all safe materials? Is it lead free? (are you SURE?) Any residues, even burnt ones, from other filaments?

    Is your build plate food-safe? Etc

    Before you answer, consider that the chinese love to put lead in damn near everything…you SURE that extruder you bought on aliexpress doesn’t have any lead in any of the gears or bearings etc?

    1. Legitimately curious. For those of us who suck solder fumes all day (with extractors for big jobs mind you) how bad is this in reality? Its a small batch, made a few times for consumption by oneself and friends. Is it really likely to shorten my life or drive me stark raving mad even if I used them every christmas for 20 years?

    2. Wouldn’t a real good solvent wash then a good dish soap wash make a 3-d printed part safe enough to bake with?

      Re lead… again, a wash should take care of it. I don’t see how a washed mould would carry and transfer any significant amount of lead. But then again, I spent the first 40 years of my life soldering with lead-based solder and I aren’t affekted in aNY, uh, er, way. Maybe.

    3. Just use a food safe shellac or Krylon clear coat and problem solved.

      No need to complicate it.

      If you want to make food molds by hand consider Smooth-on products Sorta-clear and Smooth-Sil. As they are certified for it.

    1. “the atomium is subjected to copyright”.

      a) I’m not sure that a cookie, even a Spekulatius, counts as print media under Belgian law. b) He’s not misrepresenting the Atomium or using it in a racist context. c) I’d love to see them try to enforce that one across international borders, even within Europe, much less across the Atlantic.

      I’m going to paint a picture of the Atomium and hang it in my bathroom in defiance. Send Belgian lawyers! Have them bring beer!
