Somehow it’s already December and time to start cookie baking! My soft and chewy snickerdoodles are a holiday favorite and won a few cookie competitions. I decided to adapt that recipe and bake into an easy cookie bar to slice up for my holiday cookie trays this year.

These bars be THICK and glorious. They came out pillowy soft. I adore the balance of the sweetness of the cinnamon sugar in a snickerdoodle with the tang you get from the cream of tartar. Before baking, I sprinkled these with more cinnamon sugar and when baked, it created an almost crust-like topping. The perfect sweet treat!

To make these Snickerdoodle Bars, you need a handful of ingredients:

  • Butter – make sure it’s at room temperature for the best results.
  • Granulated sugar
  • Eggs
  • Vanilla extract
  • Flour
  • Cream of tartar – this is what gives classic snickerdoodles that tasty tangy flavor!
  • Cornstarch – it helps make these bars nice and soft.
  • Cinnamon – and lots of it!
  • Baking powder
  • Salt – don’t skip out on adding a pinch of salt when baking to bring out flavors.

Recipe Tips and Suggestions:

  • For best results, make sure your butter is at room temperature before creaming with the sugar.
  • You do not need to chill this dough before baking.
  • Do not skip the cream of tartar and cornstarch in this recipe. They may not be common ingredients, but the cream of tartar is a key ingredient in a snickerdoodle cookie and the cornstarch makes the cookie nice and soft!
  • Make sure you allow for the cookie bars to cool completely for cleaner slicing.
  • Do not over mix the dough. Mixing the dry ingredients together separately will require less mixing once blended with the wet ingredients.
  • You can make these ahead a time and freeze!
