Snickerdoodles

In a mixing bowl, add softened butter and 1 1/2 cup sugar and mix until creamed. While mixing, add in eggs and vanilla extract. In a separate bowl, whisk together flour, 1/2 tsp salt, cream of tartar, and baking soda, then slowly add it to the mixing bowl a little at a time until completely incorporated, stopping in the middle to scrape the sides of the bowl to ensure it's completely mixed. Remove the bowl and set aside.

Preheat oven to 350°F.

In another bowl, add 1/3 cup sugar and ground cinnamon and toss until mixed. Roll dough into 2-inch balls and coat with the cinnamon-sugar mixture before placing them 3 inches apart on a parchment or silicone tray-lined baking sheet.

Bake at 350°F for 8-11 minutes, depending on the size of the cookies. Remove carefully from the oven and let cool for 1 minute before transferring to a cooling rack to finish setting up.

(Optional, as suggested by the author: smash the cinnamon-sugar mixture into the cookie as well as coat it.)
