Preheat your oven to 350°F (175°C).
Prepare the Cookie Dough:
In a medium bowl, whisk together the flour, cream of tartar, baking soda, and salt.
In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
Add the eggs, one at a time, beating well after each addition. Mix in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Prepare the Topping:
In a small bowl, mix together the granulated sugar and ground cinnamon.
Assemble and Bake:
Spread the cookie dough evenly into a greased 9x13-inch baking dish.
Sprinkle the cinnamon-sugar mixture evenly over the top of the cookie dough.
Bake in the preheated oven for 20-25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Cool and Serve:
Allow the cookie bars to cool in the pan before slicing into bars.
Serve warm or at room temperature.
