Method
Preparation
- Preheat your oven to 350°F (175°C).
- In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until smooth and fluffy.
- Beat in the eggs, one at a time, then stir in the vanilla extract.
- In another bowl, combine the flour, cocoa powder, cream of tartar, baking soda, and salt. Gradually add the dry mixture to the wet mixture, stirring until well combined.
- In a small bowl, mix the sugar and cinnamon for rolling.
- Roll the dough into balls and then roll each ball in the cinnamon-sugar mixture.
- Place the coated dough balls on a baking sheet lined with parchment paper, spacing them about 2 inches apart.
- Bake in the preheated oven for 10-12 minutes or until the edges are set.
- Allow to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Notes
Serve slightly warm so the chocolate breathes and the cinnamon-coating is at its most fragrant. Store in an airtight container at room temperature for up to five days. For longer keeping, freeze unbaked dough balls on a sheet, then transfer to a sealed bag; bake from frozen, adding a minute or two to the bake time.
