Preheat the oven: Set to 350°F (175°C) and line a baking sheet with parchment paper.

Make the dough: In a bowl, combine the brownie mix, eggs, oil, and flour. Mix until a thick dough forms.

Add extras: Stir in chocolate chips if desired.

Form cookies: Scoop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake: 8–10 minutes, until the edges are set but the centers remain soft.

Cool: Let cookies rest on the pan for a few minutes, then transfer to a wire rack to cool completely.
