Snickerdoodle Cookies

Directions

1. Mix the wet ingredients: Place butter in a saucepan and set over low heat until just half is melted. Cool for 5 minutes.
2. Pour cooled butter into a large bowl. Add 1 1/2 cups of sugar and whisk to combine. Whisk in eggs, one at a time, then whisk in vanilla. Whisk until mixture has consistency of wet sand. Set aside.
3. Mix the dry ingredients: In a small bowl, whisk cinnamon and remaining 3 tablespoons sugar. Set aside.
4. In a medium bowl, whisk together flour, salt, cream of tartar, and baking soda.
5. Add dries, one third at a time, to wets, mixing with a rubber spatula or wooden spoon to combine.
6. Wrap bowl with plastic wrap and refrigerate for at least 20 minutes.
7. Preheat oven to 325° F, with racks in the oven's lower and upper thirds. Line two half-sheet baking pans with parchment paper.
8. Form dough into balls about the size of whole walnuts and roll them in the reserved cinnamon sugar mixture. Set cookie balls 2 inches apart on prepared baking sheets.
9. Bake for 12 to 14 minutes, or until edges are light brown and centers are still wet; don’t overbake.
10. Immediately transfer cookies to a cooling rack. Let cool for 1 hour before serving, or used to make ice cream sandwiches.
