These chewy brown butter pumpkin snickerdoodles are a cozy fall twist on the classic cookie. Nutty browned butter, warm pumpkin spice, and a cinnamon sugar coating create the ultimate autumn treat—soft, chewy, and packed with flavor.
In a saucepan, melt the butter over medium heat. Cook until it foams, browns, and develops a nutty aroma, about 5–8 minutes. Transfer to a bowl and chill until solid but scoopable, at least 2 hours.
In a large bowl, beat the chilled brown butter with granulated and brown sugars until light and fluffy. Beat in the egg, pumpkin purée, and vanilla. In another bowl, whisk together flour, cream of tartar, baking soda, pumpkin spice, and salt. Add dry mix to wet and combine until dough just comes together. Chill dough for 30 minutes.
Preheat oven to 350°F (175°C). Mix sugar and cinnamon in a shallow bowl. Scoop 1.5 tbsp dough balls, roll smooth, then coat in cinnamon sugar. Arrange 2 inches apart on lined baking sheets.
Bake 10–12 minutes until edges are set and centers soft. Cool on sheet 5 minutes, then transfer to wire rack. Cookies will flatten slightly as they cool.
Notes
Chill both the brown butter and the dough to prevent spreading and achieve the perfect chewy texture. Cream of tartar is essential for the signature tang of a snickerdoodle.
