Later this year, DoubleTree by Hilton's signature DoubleTree Cookie will earn the distinction of becoming the first food item to be baked in space.

The experiment will involve a batch of chocolate chip DoubleTree Cookie dough and a new prototype oven from Zero G Kitchen, which specializes in appliances for microgravity use during space flights. 

Both the dough and oven will be launched in a rocket bound for the International Space Station (ISS), where astronauts plan to bake about five DoubleTree Cookies. The cookies will be baked in the week following launch, with the process recorded via NASA's livestream of the ISS.

Also involved in the project is NanoRacks, a provider of commercial space access.

According to Shawn McAteer, DoubleTree by Hilton senior vice president and global brand head, the idea for the stunt was born out of a social media interaction following Elon Musk's space launch of his Tesla Roadster and "Starman" dummy last year.

"We have a really great, savvy social media team that likes to have a little fun from time to time," said McAteer. "So, they tweeted, 'Hey Starman, do you want a cookie the next time for the ride?' We didn't hear from Elon, but Zero G Kitchen, which follows Elon and has developed tech that can actually cook and bake real earth food in space, saw our tweet. They reached out to us to see if they'd be interested in partnering with them, which we were delighted to do."

The project will make Hilton the first hospitality company to participate in research aboard the space station.

The DoubleTree Cookie has been a part of the DoubleTree flag since 1986, when the brand began giving cookies to guests as part of a turndown service. In 1995, the brand changed the tradition, offering guests a warm DoubleTree Cookie upon arrival.

"The DoubleTree Cookie is quite famous and every guest that checks into our hotel gets a cookie," McAteer said. "It's the symbol of our brand and a symbol of the warm and comfortable environment we create."
