The Stuffed Puffs company was founded in 2012 by Michael Tierney of Long Island, New York, while the marshmallow itself was invented by him 4 years back in 2008 while sitting in a friend's backyard by a campfire making s'mores. In an interview with Dave Knox of Forbes, Tierney explained the invention as; "What bothered me about the traditional s’more was that the chocolate never melted. It never looked like that TV commercial of that really ooey, gooey chocolatey s’more. It was always ice cold and slid around the graham cracker, like a hockey puck on ice. As I was sitting there, I ripped a marshmallow in half and shoved a piece of chocolate inside and put it over the fire. And of course it melted from the inside out."[1] Tierney founded Mikey's, a brand of gluten free foods to raise capital for his Stuffed Puffs brand. Later in 2018, Mikey's partnered with Factory, LLC, which led to Stuffed Puffs being put into production in Bethlehem, Pennsylvania.[2] In 2019, Stuffed Puffs began selling in Walmart stores.[2]
For summer of 2021, Stuffed Puffs launched its "Fluffing Delicious" television advertisement campaign featuring DJ Marshmello produced by Anonymous Content. This is the company's first national advertisement campaign.[3]
In 2024, Stuffed Puffs closed their Bethlehem facility and moved all production to Texas after being purchased by Mountain Franklin Foods, LLC.[4]
