Preheat your oven to 350°F (175°C).

Grease your 9x9 inch baking pan or line it with parchment paper.

In a mixing bowl, combine the brownie mix, vegetable oil, water, and eggs. Stir until well blended.

Pour the brownie batter into the prepared pan and spread it evenly.

Bake in the preheated oven for 30 to 35 minutes.

Let the brownies cool in the pan for about 10 minutes.

Cut the brownies into squares and serve.
