Preparation Steps

• Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides for easy lifting.
• In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
• In a large bowl, cream together the softened butter and 1 cup granulated sugar until light and fluffy, about 2-3 minutes.
• Beat in the egg and vanilla extract until well combined.
• Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
• Press the cookie dough evenly into the prepared baking pan.
• In a small bowl, combine the 0.25 cup granulated sugar and ground cinnamon for the topping. Sprinkle this mixture evenly over the top of the cookie dough.
• Bake for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted into the center comes out with moist crumbs, not wet batter. The center may look slightly underdone, but it will set as it cools.
• Let the cookie bars cool completely in the pan before lifting them out using the parchment paper overhang. Cut into squares and serve.
