1 stick unsalted butter, room temperature
1 1/2 cups sugar, plus 3 T sugar
2 large eggs
2 3/4 cups flour
3 tsp. cinnamon
2 tsp. cream of tartar
1 tsp. baking soda
1/4 tsp. salt
Preheat the oven to 350F and line your baking sheets with parchment paper.
In your stand mixer, mix the butter, sugar, and eggs.
In a large bowl, mix the flour, 1 1/2 cups sugar, cream of tartar, baking soda, and salt.
Pour the dry ingredients into the wet ingredients and mix until just combined. Refrigerate at least 15 minutes.
In a small bow, mix the 3 T of sugar and 3 tsp. cinnamon.
Using a small scooper (I have a 1″), scoop and roll tiny balls. Roll them in the cinnamon/sugar mixture and place onto the parchment paper.
Bake for 10-11 minutes. Not a minute more! Immediately put the cookies onto wire racks and let them cool before storing.
