1. Preheat your oven to 350°F (175°C).
2. In a mixing bowl, combine 1 box of cake mix, 1/3 cup of oil, and 2 eggs.
3. Stir until all ingredients are well combined and a sticky dough forms.
4. If the dough is too sticky, refrigerate for about 15-30 minutes for easier handling.
5. Use a spoon or cookie scoop to drop dough onto a baking sheet lined with parchment paper.
6. Leave space between each cookie to allow for spreading while baking.
7. If desired, add mix-ins like chocolate chips, nuts, or sprinkles before baking.
8. Bake in the preheated oven for 9-11 minutes until edges are set but centers remain soft.
9. Remove from oven and let cookies cool on the baking sheet for a few minutes.
10. Transfer cookies to a wire rack to cool completely.
11. Enjoy fresh or store in an airtight container for later.
12. Optionally, freeze cookie dough or baked cookies for future use.
