Preheat the oven to 350°F (180°C).
Combine 15.25 ounce yellow cake mix box, 2 eggs and ½ cup vegetable oil in a mixing bowl. Stir until all the ingredients are well combined. The mixture will be thick, shiny, and sticky.
Line a baking sheet with parchment paper or lightly grease it.
Scoop spoonfuls of the dough onto the prepared baking sheet, spacing them a few inches apart. You can also use spoons to drop them.
Bake the cookies for about 10 minutes, until the edges are lightly golden brown. The cookies may appear slightly undercooked in the center, but they will firm up as they cool.
Let cool for 10-15 minutes on a wire rack, until you can easily and carefully remove them from the baking sheet.
Transfer them to a cooling rack to cool completely.
Repeat the process with the remaining dough until all the cookies are baked.
Once the cookies have cooled completely, you can store them in an airtight container for up to a week.
