Ingredients
Method
- Preheat oven to 350°F (175°C) and line baking sheets with parchment paper or silicone mats.
- Cream softened butter in a mixing bowl, then beat in 1 1/2 cups sugar for 2–3 minutes until light and fluffy.
- Add eggs and vanilla extract, mixing until fully incorporated.
- In a separate bowl, whisk cocoa powder, flour, cream of tartar, baking soda, baking powder, salt, optional cayenne, and espresso powder.
- Slowly add dry ingredients to wet ingredients, mixing just until combined.
- Form dough into balls using 2–3 tablespoons of dough per cookie.
- Mix cinnamon and sugar for coating, then roll each dough ball thoroughly in the mixture.
- Place on baking sheets at least 2 inches apart and bake for 10–12 minutes until edges are set but centers remain soft.
- Rest cookies on baking sheet for 2 minutes, then roll again in cinnamon sugar for a crackly finish.
Notes
For deeper flavor, chill the dough for up to 48 hours before baking. Remove cookies from the oven when slightly underdone—this ensures a chewy texture.
