Chewy Snickerdoodle Cookie Bars are one of those timeless desserts that fill the whole kitchen with the sweet, cozy aroma of cinnamon sugar. There’s something about that scent that instantly takes me back to my mom’s kitchen, where a single bite always felt like a hug. However, when baked into bars, it becomes even easier and chewier.

These Snickerdoodle Cookie Bars take all the flavors you love and transform them into a simple, crowd-pleasing dessert that’s perfect for any occasion.
The Secret Behind Chewy Snickerdoodle Cookie Bars
What Makes Them Different from Classic Cookies
Unlike regular snickerdoodles that require rolling dough into balls and coating each one in cinnamon sugar, cookie bars are baked in a single pan. This not only saves time but also gives them a chewier texture that many prefer. Instead of crisp edges, you get soft, gooey squares with a rich cinnamon-sugar swirl in every bite.
Why Texture Matters
The best part of Chewy Snickerdoodle Cookie Bars is their texture. The center stays soft and moist while the edges are slightly firm. Because of this, every bite feels balanced. For people who love chewy cookies, this recipe provides the best of both worlds — the flavor of snickerdoodles and the chewiness of cookie bars.

Ingredients
2 ¾ cups (345 g) all-purpose flour
2 tsp cream of tartar
1 tsp baking soda
½ tsp fine salt
1 cup (225 g) unsalted butter, melted and cooled slightly
1 ¾ cups (350 g) granulated sugar, divided
2 large eggs + 1 yolk, room temperature
2 tsp pure vanilla extract
1 Tbsp ground cinnamon
Instructions
1. Preheat your oven to 350 °F / 175 °C. Line a 9 × 13-inch (23 × 33 cm) baking pan with parchment paper, leaving some overhang for easy removal.
2. In a medium bowl, whisk together flour, cream of tartar, baking soda, and salt.
3. In a large bowl, whisk melted butter with 1 ½ cups sugar until smooth. Add the eggs, yolk, and vanilla, mixing until fully combined.
4. Gradually add the dry ingredients into the wet mixture, stirring until a soft dough forms.
5. Spread the dough evenly into the prepared pan.
6. In a small bowl, mix the remaining ¼ cup sugar with the cinnamon. Sprinkle generously over the dough.
7. Bake for 22–25 minutes, or until the edges are golden and the center looks set.
8. Let cool completely before lifting from the pan and slicing into bars.
Notes
For extra flavor, try adding a pinch of nutmeg to the cinnamon-sugar topping. You can also drizzle a simple vanilla glaze over the cooled bars for a bakery-style finish.

Key Ingredients for the Perfect Cookie Bars
The Role of Cream of Tartar
Cream of tartar is what sets snickerdoodles apart. It gives the bars their slight tang and prevents the sugar from crystallizing, which helps keep them soft. If you skip it, you’ll still get tasty bars, but they won’t have that signature flavor.
Balancing Cinnamon and Sugar
The cinnamon-sugar coating is another essential element. When sprinkled generously over the top before baking, it creates a golden crust. As the bars bake, the sugar melts slightly, adding a caramel-like layer that enhances both texture and taste.
How to Bake Chewy Snickerdoodle Cookie Bars
Step-by-Step Method
- Preheat your oven and prepare your baking pan with parchment paper.
- Whisk together flour, cream of tartar, baking soda, and salt.
- In another bowl, beat butter and sugar until smooth.
- Add eggs and vanilla, mixing until combined.
- Slowly fold in the dry ingredients until a dough forms.
- Spread the dough evenly in the pan and sprinkle with cinnamon sugar.
- Bake until golden, but remove while the center is still slightly soft.

Pro Tips for Success
Always avoid overbaking, since bars continue to set as they cool. Also, let them rest in the pan for at least 15 minutes before slicing. This step keeps the texture chewy instead of crumbly.
