1. Prep: Preheat oven to 350°F and prepare a cookie sheet by lining with parchment or coating with cooking spray. The cookies spread out quite a bit so it may be necessary to use more than one baking sheet or bake in batches.
2. Wet Ingredients: In a medium bowl, whisk together eggs, oil, and vanilla (optional) until fully combined.
3. Combine: Add cake mix to liquid ingredients and stir with a spatula or spoon to form a smooth dough.
4. Portion: Form round balls using 2 rounded tablespoons of dough and place 3-4 inches apart on the cookie sheet.
5. Bake: Bake for 13-15 minutes, rotating halfway through. Cookies will be done when they are almost fully set on the edges and slightly golden on the bottom.
6. Store: Let cool for a couple of minutes on the cookie sheet before transferring to a wire rack to let cool completely. Store in an airtight container at room temperature for 3-4 days or in the freezer for up to 3 months.

Freeze for Later: The cookies can be frozen before or after they are baked and kept in the freezer for up to 3 months. Store in an airtight container or ziploc bag. If they have been baked, make sure they are fully cooled first.

Prepare from Frozen: Bake frozen cookie dough according to the recipe instructions – baking times will still be the same. For baked cookies, let thaw to room temperature and enjoy.
