Soft, lightly crackled Snickerdoodle Cookies with a tender chew and warm cinnamon-sugar aroma. Chilling the dough deepens flavor and controls spread for consistent results.
In a large bowl, beat butter and sugar on medium-high speed until pale and fluffy, about 2 minutes.
Add eggs one at a time with vanilla, mixing until fully incorporated and smooth.
In a separate bowl, whisk flour, cream of tartar, baking soda, and salt until combined.
Gradually add dry ingredients to the butter mixture on low speed, mixing just until combined.
Cover dough and chill for at least 1 hour (up to 48 hours).
Bake Cookies
Preheat oven to 350°F (177°C) and line baking sheets with parchment paper.
Combine sugar and cinnamon in a small bowl.
Roll chilled dough into 1½-inch balls, then roll in cinnamon-sugar to coat.
Place cookies 2 inches apart and bake one sheet at a time for 10–12 minutes, until edges are set and tops are matte.
Let cookies rest on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
Chill dough at least 1 hour for best flavor and shape.Store baked cookies in an airtight container at room temperature for up to 3 days or freeze for up to 3 months.
