Ingredients:
- 1 cup (226g) unsalted butter, softened
- 1.5 cups (330g) light brown sugar, packed
- 0.5 cup (100g) white sugar
- 1 large egg, room temperature
- 1 tbsp pure vanilla extract
- 2.75 cups (345g) all-purpose flour
- 2 tsp ground Saigon cinnamon
- 1 tsp cream of tartar
- 1 tsp baking soda
- 0.5 tsp sea salt
- 0.25 cup (50g) white sugar
- 1 tbsp ground cinnamon
Instructions:
- Cream the foundation. Place the 1 cup of softened butter and both sugars (1.5 cups brown, 0.5 cup white) into your mixer. Beat on medium high for 3-4 minutes until the mixture is pale, fluffy, and voluminous. Note: This creates the air pockets needed for a light texture.
- Add the liquids. Drop in the room temperature egg and 1 tablespoon of vanilla. Beat for 1 minute until the batter looks silky and emulsified.
- Prep the dry mix. In a medium bowl, whisk the 2.75 cups of flour, 2 teaspoons of cinnamon, cream of tartar, baking soda, and sea salt.
- Combine carefully. Turn the mixer to the lowest speed and gradually add the flour mixture. Mix until no white streaks remain, then stop immediately.
- Stabilize the dough. Cover the bowl and put it in the fridge for 30 minutes. until the dough feels firm to the touch. Note: This prevents the cookies from spreading into flat pancakes.
- Set the stage. Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper.
- Create the coating. In a small bowl, whisk together the remaining 0.25 cup of white sugar and 1 tablespoon of cinnamon.
- Scoop and roll. Use a 1.5 tablespoon scoop to form balls. Roll them in the cinnamon sugar until they are completely encrusted and sparkling.
- Bake to perfection. Place balls 2 inches apart on the sheets. Bake for 10 minutes until the edges are golden but the centers still look slightly soft.
- The carryover cook. Let the cookies sit on the hot pan for 5 minutes until they firm up enough to move, then transfer to a wire rack.
