The Best Snickerdoodle Cookie Recipe – Soft, Chewy & Full of Cinnamon

Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.

In a medium bowl, whisk together flour, cream of tartar, baking soda, salt, and optional cinnamon.

In a large bowl, cream butter and sugar until light and fluffy, about 2–3 minutes.

Add eggs one at a time, then mix in vanilla extract.

Gradually mix dry ingredients into wet mixture just until combined.

In a small bowl, combine the ¼ cup sugar and 1 ½ tablespoons cinnamon for coating.

Roll dough into 1 ½-inch balls and coat in cinnamon-sugar mixture.

Place dough balls 2 inches apart on prepared baking sheets.

Bake for 8–10 minutes until edges are set and centers are slightly soft.

Cool on baking sheet for 3–5 minutes before transferring to a wire rack to cool completely.
