Who invented s’mores? Don’t believe the myths—this is the real history

Who invented s’mores? Don’t believe the myths—this is the real history

Lots of people get credit for inventing the gooey campfire treat. But a woman named Cookie—yes, Cookie—made it into a culinary all-star. This is her story.

Birth of the 'Somemore'

Girl Scouts executives continued to formalize and expand a schedule of training events.  Wisconsin hosted the National Camp-Field-Education Conference for midwestern leaders in late September 1924, and Pennsylvania hosted the version for eastern leaders in early October. Cookie brought her usual mirth and cheer to both gatherings, and a handful of newspaper reports indicate that she shared something unusual.

The local director for Girl Scouts in Buffalo, New York, relayed to her troops her experience at the eastern conference assembling kabobs and “a new dessert called ‘Somemore’ ” at the end of a camp-wide game of tracking and observation. An assistant local director from Rochester, New York, played on the opposing team, a group that trained directly with Cookie. A few weeks later, the Rochester newspaper published a now-familiar recipe under the heading “Yummie Dessert.”

And after leaders from Kalamazoo, Michigan, had returned from the midwestern conference, the local newspaper reported that kabobs “and ‘summore’ have been introduced on the Scout menu and have already become famous.”

Well, not quite.

Her own writings on the subject are silent, but wherever Cookie went, somemores followed. Then, in the cover story for the May 1925 issue of The Girl Scout Leader magazine—mailed free to all captains, commissioners, and local directors—Cookie published a weekend hike plan with one-pot meals and an easy dessert that required no extra kitchen utensils: 

            “Somemore”

            16 graham crackers

            4 Hershey bars

            16 marshmallows

Toast the marshmallows until they are pale brown and “gooey.” Then make a sandwich of the two crackers and half a chocolate bar and put the marshmallow in between. Good!

Perhaps Cookie took inspiration from Mallomars or MoonPies, both invented in the 1910s. They used the same ingredients as a somemore, but the outer layer of chocolate devolved into a melting mess near flames. Cookie had noticed that Americans craved candy, but she could not have predicted her triumph. A troop leader in Virginia who attended a training course deemed them “most tempting.” Graham cracker crumbs tumbled into the grass at a troop leader training in Illinois, where they smushed melted chocolate with crispy marshmallows and exclaimed, “O, Girl, what joy!”

Girl Scouts in western New York wrote about somemores many times during the 1925 summer camps. A rainy night in late July left the girls in Buffalo, New York, sitting on ponchos watching their friends struggle to light a pile of damp wood. “Then it blazed up beautifully,” they wrote, “and we sang and talked and laughed and toasted ‘Some-mores.’” In a review that echoes across generations, they declared the dessert “food for the gods.”

It became the breakout year for somemores, and by the end of 1925, Girl Scouts in at least 22 states—coast to coast, and from the Great Lakes to the Gulf—had assembled the trio of ingredients around campfires, office stoves, and electric toasters using everything from wood sticks to steel knitting needles.

From the earliest mentions, Girl Scouts established ownership of their novelty and referred to it as the “Girl Scout dessert” or “a Scout specialty.” Troops also tested other names: “samoas” (now a different Girl Scout cookie), “yummies,” and “toasted marshmallow delights.” As part of a national marketing campaign, a marshmallow manufacturer released a recipe booklet in 1925 that included a “Marshmallow Graham Cracker Sandwich,” a tag as unwieldy as it was literal.

“Somemore” worked because it described the food and the feeling. “Every time you eat one, you always go back for more,” concluded the scribe for Troop 7 in her report to the Birmingham, Alabama, newspaper. Cookie once wrote that she admired Americans for their ability to “scrap, at a moment’s notice, lately cherished schemes, in favour of new ones which seem better.” The girls proved her right.

In late 1925, a Minnesota troop called the dessert s’mores—if not the first, definitely one of the earliest examples of the modern apostrophe (and long before internet claims of the word’s creation in a 1938 guidebook written by a man). A century on, s’mores have become a milestone of American childhood and the embodiment of camping. 

Cookie’s cookie

“Already this ‘Innisfree’ idea is spreading about the country,” reported the Girl Scouts national director of the camp department in 1925, and she acknowledged that more American girls were “learning how to be real campers, not merely the ‘summer resort’ kind who do not know how to fend for themselves outdoors.”

Cookie Moore’s hometown newspaper in Bexhill, England, published a letter from her rejoicing that the 1925 camping season had broken records. “So you see, guiding or scouting, it’s all the same the world over. The most use and the best fun of all the strange things we spend our lives attempting to do.”

She continued to teach at camps in Boston and then Chicago, where in 1927, as Tramping and Trailing with the Girl Scouts was published, a newspaper reported that, “The name of Christian Moore is a household word for Girl Scouts everywhere.” The national headquarters estimated that 50,000 girls would participate in pioneer camping that year.

Together with other efforts to develop a generation of leaders, such as including training courses at colleges, Cookie’s work had changed the Girl Scouts’ trajectory of growth. S’mores were a bonus, a sugary tactic in her much broader strategy of inspiring joy out under the open skies.

And yet her story is a study of legacies and what little we control of how the world remembers us.

She headed back to England in December 1928 to rejoin her Girl Guides. Camp Fire Girls tried to rebrand her signature dessert as “heavenly crisps,” yet in 1934, even their official manual conceded a final parenthetical: “(also known as s’mores).” By that point, Girl Scouts counted 350,000 active members, nearly double their former rival.

Unsurprisingly, Cookie opened her own cooking school in 1936. Decades later, she would have read about the 50th anniversary of Girl Scouts, when the organization merged its campfire goody with its even longer history of selling cookies. New in 1962: Some-Mores, a vanilla wafer and marshmallow covered with chocolate.

But no mention of the woman who popularized them. The truth behind the treat had vanished like one of Cookie’s overnight campsites.

Perhaps this anonymity was intentional. Her book of letters was published in 1924 without her name credited. Hail, Girl Scouts! only listed “a Girl Guide” on the cover, and her views on service reflected a similar mindset. “No one is indispensable,” she wrote in 1927. “This should be the motto of every Girl Scout Leader. Once she has realized this, she begins automatically to train others to take her place.”

Cookie Moore lived the rest of her life in Bexhill’s seaside tranquility and never had children. She eventually moved to a retirement home. She meandered into the gardens there, a few months short of her 96th birthday, and died suddenly—in the wilds, as always.

Considering her American escapades of the early 1920s, Cookie once wrote, “I’d give a good deal to be allowed to return and see this wonderful country, say in a hundred years’ time.” If she were to visit this weekend, she wouldn’t recognize much. Innisfree’s log cabin has tumbled. The stone chimney remains as a beacon of the memories, but the old trails have overgrown.

Yet any bewilderment from the current state of the world would fade when Cookie settled onto a blanket among a circle of uniformed girls as a turquoise twilight dusted the horizon and, at her feet, the glow of campfire coals on the confection she helped us learn to love.
