These brown butter snickerdoodles are soft, chewy, and packed with warm cinnamon flavor. Browning the butter adds a rich caramel-like depth that makes these cookies taste extra cozy and bakery-style.
Brown the butter in a saucepan over medium heat for 5 to 7 minutes until golden brown and nutty-smelling.
Transfer to a bowl and cool for 15 to 20 minutes.
Whisk together flour, baking soda, cream of tartar, cinnamon, and salt.
Mix sugars into the browned butter, then whisk in eggs and vanilla.
Stir in dry ingredients until just combined.
Chill dough for at least 1 hour.
Preheat oven to 350°F and line baking sheets with parchment paper.
Mix rolling sugar and cinnamon in a small bowl.
Scoop dough into 2-tablespoon balls and roll in cinnamon sugar.
Bake for 10 to 12 minutes, until edges are set and centers are slightly soft.
Cool on the baking sheet for 5 minutes, then transfer to a wire rack.
