- Preheat oven to 325°F. Line a baking sheet with a parchment paper and set aside.
- In the bowl of your stand mixer fitted with the paddle attachment mix the butter, granulated sugar, and light brown sugar together on medium speed until light and fluffy, 2-3 minutes. Add in the egg, the yolk, vanilla, baking soda, cream of tartar, salt, and cinnamon and mix for 1 minute, scraping the sides of the bowl as necessary.
