3cups(360g)all-purpose flour, (stir, spoon, and level)
2tspcream of tartar
1tspbaking soda
½tspsalt
Cinnamon-Sugar Topping:
2Tbspgranulated sugar
1 ½tspground cinnamon
Instructions
Preheat oven to 350 degrees Fahrenheit. Lightly grease a 13x9-inch baking dish with cooking spray, or line with parchment paper.
In a stand mixer fitted with the paddle attachment, cream the butter and sugar. Add the eggs and vanilla. Mix well. Scrape bowl.
Combine the flour, cream of tartar, baking soda, and salt in a separate bowl. Add dry ingredients to wet ingredients and mix until incorporated.
Press dough onto the bottom of the prepared baking dish. Smooth with a mini rolling pin that has been lightly greased with cooking spray to prevent sticking. Combine the cinnamon-sugar topping. Sprinkle evenly over the top of the dough.
Bake at 350˚F for 25-30 minutes. Remove from oven and immediately use a serving spatula to press the edges down while still hot, if they are higher than the center. (For even looking bars.)
Allow to cool completely. Then cut bars and enjoy.
Notes
*I like to use parchment paper to pull the snickerdoodle bars out of the pan for easy cutting and serving. I will cut off a sliver of the crusty edges and then cut squares, so each bar is like a middle piece. Of course we still eat the crusty edges too.
