Ingredients

• 0.5 cups unsalted butter , softened
• 0.5 cups white sugar
• 0.25 cups firmly packed brown sugar
• 1 large egg , at room temperature
• 2 teaspoons vanilla extract
• 1.25 cups all-purpose flour
• 0.5 teaspoons cream of tartar
• 0.5 teaspoons baking soda
• 0.5 teaspoons salt
• 0.25 teaspoons ground cinnamon , divided
• 0.13 teaspoons ground nutmeg

Instructions

1. 1 Preheat the oven to 350 degrees F (175 degrees C). Line an 8x8-inch square pan with enough parchment paper to have overhang on all sides.
2. 2 Cream together butter, 1/2 cup white sugar, and brown sugar in a bowl with an electric mixer until light and fluffy. Mix in egg and vanilla until thoroughly combined. Add in flour, cream of tartar, baking soda, salt, 1/4 teaspoon cinnamon, and nutmeg, and mix until a dough just begins to form.
3. 3 Place dough into prepared pan. Using lightly floured hands, press dough firmly and evenly into the bottom of the pan.
4. 4 In a small bowl, mix together 1 tablespoon white sugar and 1/2 teaspoon cinnamon. Sprinkle evenly over the dough.
5. 5 Place pan into the preheated oven, and bake just until the dough in the center of the pan feels barely set, 20 to 23 minutes. Do not over bake.
6. 6 Allow cookies to cool in pan for 10 minutes before removing to a wire rack to cool completely. Cut into 16 bars.
