Ingredients
Equipment
Method
- Preheat the oven to 350°F.
- Line a large baking sheet with parchment paper.
Make the dough
- In a large bowl, stir together the cake mix and cream of tartar.
- Add the eggs and oil, then beat until a thick dough forms.
- Cover and chill the dough for 30 minutes.
Make the coating
- Stir the sugar and cinnamon together in a small bowl.
Shape and bake
- Scoop the dough into 1 1/2-tablespoon portions and roll them into balls.
- Coat each ball in the cinnamon-sugar and place them about 2 inches apart on the prepared baking sheet.
- Bake for 10–12 minutes, until the edges are set and the centers look puffed and soft, baking in batches as needed.
- Cool the cookies on the baking sheet for 5 minutes.
- Transfer the cookies to a wire rack to cool.
Notes
Chill the dough for the full 30 minutes to make it easier to roll and coat. Store in an airtight container in the refrigerator for up to 5 days; freeze for up to 2 months. For a gluten-free option, use a gluten-free yellow cake mix.
