Preheat the oven to 350 F. In a medium bowl, whisk together flour, salt, baking soda, cream of tartar, cinnamon, ginger, and cloves. In another large bowl, combine butter with both sugars and molasses, mix until fluffy.
Add in egg and vanilla extract, and mix until smooth. Add in the flour mixture, mix until it is fully combined. Press the cookie dough into a greased 8-inch square baking dish.
In a small bowl, combine sugar and cinnamon. Sprinkle over the cookie dough. Bake for 15-20 minutes.
