Preheat the Oven: Begin by preheating our oven to 350°F (175°C). This ensures our cookies bake evenly.
Cream the Butter and Sugar: In a large mixing bowl, we will cream together the softened butter and 1 1/2 cups of granulated sugar until light and fluffy. This step incorporates air, leading to chewy cookies.
Add the Eggs: Next, we will beat in the two large eggs, one at a time, making sure that each is fully incorporated before adding the other.
Combine the Dry Ingredients: In another bowl, whisk together 2 3/4 cups of all-purpose flour, 2 teaspoons of cream of tartar, 1 teaspoon of baking soda, and 1/4 teaspoon of salt. This mix of dry ingredients is essential for structure and flavor.
Mix Dry Ingredients with Wet Ingredients: Gradually add the dry ingredients to the butter-sugar-egg mixture. Blend until just combined to prevent overmixing, which could lead to tough cookies.
Prepare the Cinnamon Sugar: In a small bowl, combine the remaining 1/2 cup of granulated sugar with 2 tablespoons of ground cinnamon. This mixture will coat the cookies.
Form the Cookies: Scoop tablespoon-sized amounts of dough and roll them into balls. Then roll each ball in the cinnamon-sugar mixture to coat evenly.
Bake: Place the coated dough balls on ungreased baking sheets about 2 inches apart. Bake in our preheated oven for 10-12 minutes, until the edges are set and the tops appear crackled but still soft.
Cool: Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes. Then transfer them to wire racks to cool completely.
Enjoy!
