Preheat your oven to 175°C (350°F). Line a baking sheet with parchment paper.
Mix the lemon cake mix, eggs, and vegetable oil in a large bowl until a dough forms.
Chill the dough in the fridge for about 5 minutes to make it easier to handle (optional but recommended).
Scoop tablespoon-sized amounts of dough, roll them into balls, then coat each ball in powdered sugar.
Place the dough balls on the prepared baking sheet, spacing them about 5 cm apart.
Bake for 9–11 minutes or until the cookies are just set and slightly golden at the edges.
Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Serve and enjoy your chewy, crinkled lemon cookies!
