If you love classic snickerdoodle cookies with their soft centers and cinnamon-sugar coating, you’re going to adore these Cinnamon Sugar Snickerdoodle Bars! They have all the delicious, cozy flavors of traditional snickerdoodles but come in a simple, sliceable bar form. No rolling dough or multiple batches required—just mix, spread, bake, and enjoy! Perfect for an easy weeknight treat, potluck, or anytime you’re craving something sweet and cinnamon-spiced.
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan and line it with parchment paper, leaving some overhang on the sides. This makes it easier to lift the bars out later!
In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy, about 2-3 minutes. Add the egg and vanilla extract, mixing until well combined.
In a separate bowl, whisk together the flour, baking powder, baking soda, cream of tartar, and salt.
Gradually add the dry ingredients to the wet mixture, stirring just until everything is combined. The dough will be thick and slightly sticky.
Spread the dough evenly in your prepared baking pan. Use a spatula or your hands (dampening them slightly can help) to smooth the top, ensuring an even layer.
In a small bowl, mix together the granulated sugar and ground cinnamon for the topping.
Evenly sprinkle the cinnamon sugar mixture over the top of the dough, covering it completely.
Bake in the preheated oven for 20-25 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean.
Allow the bars to cool in the pan for about 10 minutes. Then, lift them out using the parchment paper and transfer to a wire rack to cool completely. Once cool, cut into squares or bars.
Enjoy these delightful snickerdoodle bars with a glass of milk or your favorite beverage for the ultimate treat! 🥛❤️
