Method
Preparation
- Preheat your oven to 350°F (175°C) and line a cookie sheet with parchment paper.
- In a large mixing bowl, combine the melted butter and cocoa powder. Whisk until smooth.
- Stir in the granulated sugar and brown sugar until well blended.
- Add in the egg, egg yolk, and vanilla extract. Stir until fully incorporated.
- In another bowl, whisk together the flour, cream of tartar, baking soda, salt, and ground cinnamon.
- Gradually add the dry ingredients to the wet mixture, stirring until a stiff dough forms.
Rolling and Baking
- In a small mixing bowl, combine the sugar, cinnamon, and cocoa powder for rolling.
- Scoop about 1 1/2 tablespoons of dough and roll it into a ball.
- Roll each ball in the cinnamon-sugar mixture, then place them on the baking sheet, spaced at least 2 inches apart.
- If you want flatter cookies, gently press them down a little bit before baking.
- Bake for about 8 minutes until soft in the center. Let them cool completely on the baking sheet.
Notes
For a fun variation, swap out half the cocoa for peanut butter powder. Time-saving tip: Prep your dough and chill it in the fridge for 30 minutes to create a firmer dough.
