Preheat the oven to 350°F. Line baking sheets with parchment paper.

Place the brownie mix in a large bowl. Add eggs, flour, and oil. Mix until a thick batter forms.

Stir in your preferred mix-ins such as chocolate chips or nuts.

Scoop 2 tablespoon-sized balls of dough onto the prepared baking sheets, spacing them apart.

Bake for 8-12 minutes until they are just set and glossy. Let cool before serving.
