Matt Nader, co-founder of the Blue Chip Cookie Company in San Francisco, established National Cookie Day in 1987 as a promotional event during the holiday baking season. No official press release from the founding has been independently located, though multiple sources corroborate the attribution.
Americans consume over 7 billion chocolate chip cookies every year. Cookie consumption peaks in December, when holiday baking traditions turn kitchens across the country into production lines of sugar cookies, gingerbread, and snickerdoodles. National Cookie Day on December 4 lands at the start of that annual surge.
The cookie itself has a longer history than most people assume. What started as a 7th-century Persian experiment with sugar-sweetened wafers evolved through centuries of European baking into the thousands of varieties sold today in a U.S. market worth over $10 billion. The holiday's December timing is deliberate: Matt Nader placed it at the opening of the season when Americans bake and buy the most cookies.

The cookie's origin story begins not in an American bakery but in 7th-century Persia, where bakers first experimented with sugar-sweetened wafers. These early creations were functional: bakers used small amounts of cake batter to test oven temperatures before committing a full batch. The test cakes tasted good enough to keep, and the concept spread westward along trade routes.
By the 14th century, cookies had reached Europe. The Dutch refined them into a tradition, giving them the name "koekje," meaning "little cake." When Dutch settlers arrived in New Amsterdam in the 17th century, they brought their cookie recipes with them, planting the seed of what would become an American staple.
The most consequential moment in American cookie history came in 1938 at the Toll House Inn in Whitman, Massachusetts. Ruth Graves Wakefield, a dietitian and chef who ran the inn with her husband, added chopped pieces of a Nestlé semi-sweet chocolate bar to her butter cookie dough. The chocolate held its shape instead of melting, producing a new cookie she named the Toll House Chocolate Crunch Cookie. She later sold the recipe rights to Nestlé for a symbolic one dollar and a lifetime supply of chocolate. Nestlé began printing the recipe on its packaging, and by World War II, soldiers were sharing Toll House cookies in care packages, spreading the recipe nationwide.
The postwar decades saw cookies evolve from a homemade staple into a commercial category. Brands like Nabisco, with its Oreo (introduced in 1912), and later Mrs. Fields and the Blue Chip Cookie Company built national chains around fresh-baked cookies. By the 1980s, specialty cookie stores were a fixture in American malls and shopping districts.
Matt Nader, who co-founded Blue Chip Cookie Company with his wife Lori in San Francisco in 1983, established National Cookie Day in 1987. He set the date on December 4, at the start of the holiday baking season, when cookie sales and home baking both peak. Sesame Street had included a "National Cookie Day" on its calendar as early as 1976, but Nader's version, backed by a growing franchise chain operating from its original Fisherman's Wharf location, became the observance that stuck.
