1-First, preheat your oven to 350 degrees Fahrenheit and line baking sheets with parchment paper to avoid sticking.

2-Next, cream the softened butter and granulated sugar in a large mixing bowl for 4 to 5 minutes until light and fluffy, scraping the sides occasionally for even texture.

3-Then, add the eggs and pure vanilla extract, and cream for an additional 1 to 2 minutes to blend everything well.

4-After that, stir in the all-purpose flour, cream of tartar, baking soda, and salt until just combined, being careful not to overmix.

5-In a small bowl, mix the sugar and cinnamon to create the cinnamon-sugar mixture.

6-If you like, wrap the dough and refrigerate it for 20 to 30 minutes to enhance flavor and texture though it’s optional for quicker prep.

7-Now, roll the dough into small balls until they’re smooth and round, then roll each ball twice in the cinnamon-sugar mixture to fully coat for that signature flavor.

8-For flatter cookies, gently press down the center of each ball before baking.

9-Place them on the parchment-lined baking sheet and bake for 9 to 11 minutes until the edges are lightly golden.

10-Finally, let the cookies cool on the baking sheet for several minutes before transferring them to a wire rack.
