Allrecipes' Grandma Ruth's Snickerdoodles

Preheat the oven to 400°F (200°C) and line two baking sheets with parchment paper or lightly grease.

In a large mixing bowl, beat 1 ½ cups white sugar, softened butter, and eggs together using an electric mixer until smooth and creamy.

In a separate bowl, whisk together the all-purpose flour, cream of tartar, baking soda, and salt.

Gradually blend the dry ingredients into the creamed butter mixture until a cohesive dough holds together.

In a small shallow bowl, stir together 2 tablespoons sugar and 2 teaspoons cinnamon for the coating.

Shape dough into 2-teaspoon sized balls (about 1 inch), and roll thoroughly in the cinnamon-sugar mixture to coat evenly.

Arrange the coated balls 2 inches apart on the prepared baking sheet.

Bake on the center rack at 400°F (200°C) for 7 to 8 minutes until lightly set.

Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
