The classic s’more was created nearly 100 years ago, and traditionally this treat has had only three ingredients: a toasted marshmallow, chocolate and graham crackers. To celebrate this milestone and the upcoming National S’mores Day, Jet-Puffed Marshmallows is looking for help in finding a fourth ingredient to be added to the s’more.

The brand is challenging the nation to nominate the ‘official’ fourth ingredient to the classic trio. It’s partnering with Buddy Valastro of Carlo’s Bakery to judge the nominations and ultimately select a final winner via TikTok.

To nominate an ingredient, fans can go to TikTok starting Wednesday, August 4 through midnight on National S’mores Day (August 10) and present their ideas using the hashtag #JetPuffedSmourth for a chance to win a $10,00 cash prize, a lifetime supply of Jet-Puffed marshmallows and the winning recipe to be featured as the ‘official’ Jet-Puffed S’more on the back of packs.
