Snickerdoodles are soft, chewy cookies rolled in cinnamon sugar before baking, which gives them their crackled surface and warm spiced coating. Cream of tartar in the dough adds a mild tang that sets them apart from a standard sugar cookie. The whole batch bakes up in under 30 minutes.
Preheat Oven: Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper for easy cleanup.
Prepare the Dough: In a mixing bowl, cream together the softened butter, granulated sugar, and light brown sugar using a hand mixer until light and fluffy, about 2-3 minutes. Add the egg and vanilla extract, beating well until combined.
Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, cream of tartar, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Avoid overmixing to maintain a tender cookie texture.
Prepare the Coating: In a small bowl, mix the granulated sugar and ground cinnamon for the spice coating.
Shape the Cookies: Using a cookie scoop or your hands, shape the dough into 1-inch balls. Roll each ball in the cinnamon sugar mixture until fully coated.
Bake: Place the coated dough balls onto the prepared baking sheet, spaced 2 inches apart. Bake for about 10 minutes or until the edges are lightly golden and the center is set.
Cool: Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack. This allows them to firm up and achieve the perfect chewy-center consistency.

Notes
For an extra flavor twist, add a pinch of nutmeg to the cinnamon-sugar coating.
Use soft butter to ensure a smooth, creamy dough.
If you find the dough too soft, refrigerate for 30 minutes before rolling into balls.
