Did you know

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.

Ingredients

  • 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.
  • Cream of tartar. This is there for both texture and helps to leaven the cookie bars. It helps stop the sugars from crystalizing, which leads to a softer cookie.
  • Granulated white sugar. Use it in the cookie dough and the sugar mixture for rolling.
  • All-purpose flour, baking soda and salt. The other dry ingredients.
  • Vanilla. Use a vanilla paste or a good-quality vanilla extract.
  • Ground cinnamon – This is gives it the classic snickerdoodle flavor.

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

Equipment

  • Electric mixer – 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.
  • 8×8 pan – I used an 8×8-inch square pan.

Instructions

  1. Line an 8×8 pan with enough parchment paper so you can easily lift the baked cookie from the pan once it is baked.
  2. Beat together butter and sugar until light and creamy.

Baking

Bake the cinnamon cookie bars until the edges are baked and the middle is just set. Don’t over-bake them. Let the pan cool for 10 minutes before removing the cookie. Let it cool further on a wire rack.

Once cooled, cut the soft cookie bars into 16 pieces.
