Preheat oven to 350°F. In a medium-sized bowl, whisk together oil, salt, and eggs until well combined. Add the cake mix and mix until fully combined, about 2 minutes. Refrigerate for 20 minutes.

Line 2 rimmed baking sheets with parchment paper. Portion out heaping tablespoons of dough and roll them in your hands to form round balls. Place each ball about 2 inches apart on the baking sheet (Note: the cookies will spread out considerably, so it’s important to leave plenty of space).

Bake in preheated oven for 10-12 minutes, just until the edges begin to brown slightly. Allow the cookies to cool for 10 minutes on the baking sheet before removing them to a wire rack to finish cooling.
