Ingredients
Method
- Preheat the oven to 400°F (200°C). Line a cookie sheet with parchment paper or a silicone baking mat.
- In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt. Set aside.
- In a large bowl, cream the butter and sugar together until light and fluffy, about 2–3 minutes.
- Add the eggs one at a time, mixing well after each addition. Scrape down the sides of the bowl as needed.
- Mix in the vanilla extract until fully combined.
- Add the dry ingredients to the wet ingredients and mix just until combined.
- In a small bowl, combine the remaining sugar with the ground cinnamon.
- Roll the dough into 1-tablespoon-sized balls, then roll each ball in the cinnamon sugar mixture.
- Place the dough balls on the prepared cookie sheet, spacing them about 2 inches apart.
- Bake for 6–8 minutes, until the edges are set but the centers are soft.
- Let cookies rest on the baking sheet for 2–3 minutes before transferring to a cooling rack.
Notes
For extra-soft cookies, avoid overbaking. Store cooled cookies in an airtight container at room temperature for up to 5 days.
