2023 Southern California Gingerbread Challenge

Experience Holiday Magic In a Gingerbread Village Inspired by Iconic Structures

It's almost time for the sweetest structural engineering event of the year—the 2023 SoCal Gingerbread Challenge! Join SEAOSC in Tustin, CA, this December for a whimsical, family-friendly event conveniently located in The District at Tustin Legacy for all your holiday shopping.

What Is the Southern California Gingerbread Challenge?

Organized by the Structural Engineers Association of Southern California (SEAOSC), the SoCal Gingerbread Challenge is an annual holiday tradition encouraging engineering professionals across Southern California to get creative and construct elaborate but structurally sound buildings from gingerbread, candy, and icing. After an intense build night, the gingerbread creations are put on public display for a three-day exhibition, during which the public is invited to vote for their favorites.

But that's not all! During the three-day SoCal Gingerbread Challenge exhibition, people of all ages can build their own gingerbread creations. Make your dream house, then shop while you wait for it to dry. When you return, you can test your design on our Shake Table to see if it would hold up in an earthquake! Real structural engineers will be standing by to answer your pressing questions and assist with the building and testing processes.

Why You Should Attend the 2023 Southern California Gingerbread Challenge?

Here are a few reasons why you should bring your loved ones to the 2023 Gingerbread Challenge:

  • Marvel at the breathtaking gingerbread structures on display. From intricately detailed movie sets to imaginary villages, you'll be amazed by creativity and craftsmanship.
  • This event is perfect for all ages. Bring your children, grandchildren, a date, or friends to create cherished memories with loved ones.
  • Get in on the action by voting for your favorite gingerbread structure. Your opinion matters, and your votes will help determine the winners.
  • Every vote also acts as a donation to a local non-profit organization. Help a good cause this holiday season!
  • Build a gingerbread structure of your own! Aspiring engineers of all ages can build an innovative structure all their own, and test it’s earthquake readiness on a seismic shake table!


We can't wait to see you at the 2023 SoCal Gingerbread Challenge. This delightful event will surely warm you up and add a touch of sweetness to your holiday season!
