Table of Content
If you love blondie bars or snickerdoodles, you will love these snickerdoodle cookie bars. Made with a layer of cinnamon sugar in between and on top of the bars, these are the perfect dessert bars to have during fall or the holiday season. They are based on the classic cookie just made in bar form and oh so delicious. In fact, it's like a blondie bar loaded with cinnamon sugar.
Why make these bars?
- These bars are soft and chewy, with a light cinnamon flavor. This simple recipe makes the best snickerdoodles ever.
- And most of the ingredients are simple pantry staples or easy to find.
- These are kids' favorite bars, so make sure to double the recipe.
- Also, one of the secret ingredients in these bars is a cream of tartar. This is what gives these snickerdoodle bars that slightly tangy flavor.
- In addition, they are easy to make. I am using a stand mixer (or hand mixer) but you can also use a large bowl with a whisk or spatula.

Ingredients and substitutes
- Unsalted butter - I like to use unsalted butter in all my baking, so I can control the amount of salt. And yet, if you must use salted butter omit the salt in the recipe.
- All-purpose flour - I always use all-purpose flour with great success. You do not need any other flour.
- Cinnamon - Use a good quality cinnamon powder from a trusted source. Cheap brands don't give the best flavor.
- Sugar - I've used both white and light brown sugar. White sugar adds a nice crispness while the brown sugar will keep them soft and chewy.
- Vanilla extract - You can use a teaspoon vanilla extract, vanilla bean paste or substitute some sugar for vanilla sugar.

How to make snickerdoodle bars
- Preheat the oven at 375°F / 190°C / Gas Mark 5. Prepare a 9 x 9-inch square pan with cooking spray or line with parchment paper.
- Cinnamon sugar - Combine the granulated sugar and ground cinnamon in a small bowl. Set aside.

- Dry ingredients - In a medium bowl, combine the all-purpose flour, cream of tartar, baking soda, and salt.
- In the bowl of a stand mixer with the paddle attachment(or hand mixer), cream the unsalted butter with both the white and brown sugar until light and fluffy.
Pro tip - The butter must be at room temperature, not too soft. And you want the sugar to almost dissolve in the butter.

- Add the eggs, one at a time, followed by the flour mixture. Combine well but do not overmix.
Pro tip - We do not want to activate the gluten in our flour so do not overmix.

- Transfer half the dough to the prepared baking pan. Spread the dough evenly. Sprinkle half the cinnamon-sugar mixture. Then, top with the remaining dough and more cinnamon-sugar mixture.
Pro tip - The cookie dough can be kept in the fridge for 2 to 3 days. You can even freeze it for up to 3 months.

- Bake for about 30 minutes. Then, cool in the pan for another 10 minutes.
- When cooled, cut into 16 squares as shown in the video
Pro tip - Transfer to an airtight container. - These bars will stay fresh for up to 7 days at room temperature. They can also be frozen for up to 3 months.

- Variations:
- Chocolate chips - Add ½ cup of white chocolate or bittersweet chocolate chips to the bars.
- Glaze - Drizzle some melted chocolate over the bars before or after cutting them into squares or bars.
Tips for success
- Use room temperature butter but make sure it's not too soft or melted. Otherwise, the cookies will spread too much.
- And I like using a combination of white and brown sugar for the best flavor. But, you can also use all light brown sugar.
- This recipe uses cream of tartar and baking soda instead of baking powder. While you can use 1 ½ teaspoon of baking powder with ½ teaspoon of baking soda instead, the true flavor of a snickerdoodle comes with the addition of cream of tartar. It adds tartness as well as softness to the cookies and increases the power of leavening in the bars.
- Make-a-head bars - You can keep the dough in the refrigerator for up to 3 days. Or freeze the dough for up to three months in the freezer. When baked from frozen, it may require 5 to 8 minutes more.
