Soft Snickerdoodle Cookie Bars

Your favorite cookie, but made as Snickerdoodle bars! They’re thick and soft, with a slight crunch from the cinnamon sugar. Snickerdoodles are such a classic cookie. They’re chewy cookies with the best soft texture and slightly tangy flavor from the added cream of tartar.

When you think of a classic Snickerdoodle cookie, you think of individual cookies. However, this Snickerdoodle cookie bar recipe pays homage to how the first traditional Snickerdoodles were made.

The first printed Snickerdoodle recipes were more of a cake cut into bar form. Later on, they were baked as drop cookies, where the batter was spooned from the bowl onto a baking sheet. The drop cookies were sprinkled with cinnamon sugar on the baking sheets.

These days, snickerdoodle cookies are often rolled entirely in a cinnamon-sugar mixture as opposed to just being sprinkled with it.

I love cookie bars. This Snickerdoodle bar recipe tastes like a cookie, but individual rolling is unnecessary! The soft dough is pressed into a baking pan, then the cinnamon sugar mixture is sprinkled on the bars. Once baked, they are cut into individual pieces. 

Ingredients

Find the actual ingredient amounts for this easy Snickerdoodle bars recipe in the printable recipe card at the bottom of this post. Here is a rundown of what you will need –

  • Butter at room temperature. This can be unsalted butter or salted butter. If using salted butter, you can slightly reduce the salt in the rest of the recipe.
  • Granulated white sugar. Use it in the cookie dough and the sugar mixture for rolling.
  • Vanilla. Use a vanilla paste or a good-quality vanilla extract.
  • Egg.
  • All-purpose flour.
  • Cream of tartar. Cream of tartar is one of the ingredients in these chewy Snickerdoodle bars. It is there for both texture and helps to leaven the cookie bars and baking soda. Cream of tartar is very acidic. In baked goods, it helps stop the sugars from crystalizing, which leads to a softer cookie.
  • Baking soda. The other leavening agent is the cookie dough. 
  • Ground cinnamon. A little ground cinnamon goes in the cookie dough and some in the crunchy cinnamon sugar mixture for topping.
  • Salt. A flavor enhancer.

Cream of tartar substitute

If you have no cream of tartar, you can use baking powder. The baking powder already contains cream of tartar and baking soda. When using baking powder, omit the cream of tartar and baking soda.

Less cream of tartar is in baking powder than used in this recipe, so the taste will be slightly different and will mellow the flavor. However, it is still a great substitute if you have no cream of tartar.

Replace the ½ teaspoon of cream of tartar and ¼ teaspoon of baking soda with ½ teaspoon of baking powder.

Equipment

These easy cookie bars are quickest to make using an electric or stand mixer because the butter and the sugar need beating. If you have none, it can be made by hand. This will take a little effort to cream the butter and sugar together.
