Method
Preparation
- In a medium bowl, whisk together the flour, cocoa powder, cream of tartar, baking soda, ground cinnamon, and salt. Set aside.
- In a large bowl, beat the softened butter, granulated sugar, and brown sugar until creamy and smooth, about 2 to 3 minutes.
- Add the eggs and vanilla extract, mixing until well combined and glossy.
- Gradually add the dry ingredients to the wet mixture, stirring until a cohesive dough forms, being careful not to overmix.
- Cover the dough with plastic wrap and chill in the refrigerator for at least 2 hours.
- Preheat the oven to 350°F (177°C) and line baking sheets with parchment paper.
- In a small bowl, combine 1/3 cup granulated sugar and 1 teaspoon ground cinnamon for the topping and mix well.
Baking
- Roll portions of dough into balls and coat in the cinnamon-sugar topping. Place on prepared baking sheets.
- Bake for 13 to 15 minutes or until edges are set but centers remain soft.
- Allow cookies to cool on baking sheets for 10 minutes before transferring to a cooling rack.

Notes
For a slightly taller cookie, chill scooped dough balls briefly. Store baked cookies in an airtight container at room temperature for up to 4 days.
