Creating these amazing snickerdoodles is straightforward if you follow these simple steps:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C) and lining two baking sheets with parchment paper.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt; set aside.
3. Cream Butter and Sugar: In a large bowl, beat the softened butter and 1 1/2 cups of sugar together until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract, mixing until fully incorporated.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, stirring until just combined. Do not overmix.
6. Prepare Cinnamon-Sugar: In a small bowl, mix together the ground cinnamon and 2 tablespoons of granulated sugar.
7. Shape the Dough: Scoop out tablespoon-sized portions of dough and roll them into balls. Then, roll each ball in the cinnamon-sugar mixture until fully coated.
8. Place on Baking Sheets: Arrange the coated dough balls on the prepared baking sheets, spacing them about 2 inches apart.
9. Bake: Place the baking sheets in the oven and bake for 10-12 minutes or until the edges are set and slightly golden. The centers will appear soft.
10. Cool: Remove from the oven and allow the cookies to cool on the baking sheets for 5-10 minutes before transferring them to a wire rack to cool completely.

These steps will guide you in creating incredible snickerdoodles with ease and success.
