Brownies Recipe History: Origin, Evolution, and Classic Variations

When you bite into a fudgy brownie, you’re tasting a dessert that was accidentally invented in the late 1800s—brownie, a dense, chocolate-rich square dessert that sits between cake and cookie. Also known as chocolate brownie, it wasn’t designed to be a star—it was meant to be a simple, quick treat for busy households. Unlike cakes that needed hours to bake and layers to assemble, brownies came together in one pan, with no frosting, no piping, just chocolate, sugar, and a little flour. That simplicity is why they stuck around.

The first brownie recipe, a 1896 version from the Boston Cooking-School Cook Book. Also known as Fannie Farmer brownie, it was called a "Brownie" and called for melted chocolate, butter, sugar, and eggs—no flour, no leavening. That’s right: the original didn’t even have flour. It was more like a thick chocolate slab, dense and chewy. By 1906, recipes started adding flour to make them cake-like, and that’s when the modern brownie began to take shape. Around the same time, bakers in Chicago and Philadelphia started selling them in dime stores, wrapped in wax paper. They were cheap, portable, and hit the sweet spot for working families.

What really pushed brownies into the spotlight was the chocolate industry, companies like Hershey’s and Baker’s Chocolate that started marketing pre-measured chocolate bars for home bakers. Also known as chocolate baking squares, these made it easier for anyone to bake a perfect brownie without measuring cocoa powder or melting blocks. Suddenly, brownies weren’t just a regional snack—they became a national favorite. The 1950s brought the fudgy vs. cakey debate, and by the 1980s, brownies had their own cult following: walnuts, chocolate chips, sea salt, even peanut butter swirls. Today, you can find vegan brownies, gluten-free brownies, and brownie sundaes—but they all trace back to that one 1896 recipe that didn’t even call for flour.
