Preheat your oven to 350°F (175°C) and grease an 8×8 inch baking pan.

In a large bowl, whisk together the all-purpose flour, sugar, cocoa powder, baking powder, and salt until well combined.

In another bowl, mix the vegetable oil, milk, and vanilla extract until smooth.

Pour the wet mixture into the dry mixture and stir gently until fully incorporated. Be careful not to overmix!

If you’re feeling indulgent, fold in the chocolate chips at this point.

Transfer the batter to your prepared baking pan and spread it evenly.

Place the pan in the oven and bake for 25-30 minutes. To check if they’re done, insert a toothpick into the center; it should come out with a few moist crumbs (but not wet batter).

Once baked, allow the brownies to cool in the pan for about 10 minutes before transferring to a cooling rack. Cut them into squares and indulge!
