– ½ cup softened butter – ½ cup shortening I used butter flavored Crisco – 1 ½ cups sugar – 2 eggs – 1 TBSP vanilla – 2 ¾ cups flour + 2 TBSP flour – 2 tsp cream of tartar – 1 tsp baking soda – ½ tsp salt
Prep the cinnamon sugar mixture by combining them in a shallow bowl and stirring until the cinnamon is well incorporated. Cream together butter, shortening, 1 ½ cups sugar, the eggs and the vanilla extract.
In a separate bowl, whisk together the flour, cream of tartar, soda and salt.
Pour the dry ingredients into the butter sugar mixture, mixing as you go. Scoop level mounds of dough and roll into a ball.
Roll the balls of dough in cinnamon/sugar mixture, then spoon cinnamon-sugar mixture over each cookie, turning once and doing the same on the other side. Place 2 inches apart on baking sheets lined with parchment paper.
Bake 8 minutes exactly! Remove from oven and let cookies cool on the baking sheets for an additional 2-3 minutes. Transfer to a cooling rack to cool completely.
