Preheat your oven according to the package instructions (usually 325°F to 350°F).
Grease or line an 8×8-inch baking pan with parchment paper.
In a large mixing bowl, combine the brownie mix, melted butter, milk, eggs, vanilla extract, espresso powder, and salt.
Stir until just combined. Do not overmix.
Fold in chocolate chips or chunks if using.
Pour the batter into the prepared baking pan and spread evenly.
Bake according to the time on the box or until a toothpick inserted in the center comes out with a few moist crumbs.
Allow to cool in the pan for at least 20 minutes before cutting and serving.

Using butter instead of oil adds richness and flavor.
Milk makes the texture softer and more decadent.
Adding espresso powder deepens the chocolate taste without making it taste like coffee.
Don’t overbake—slightly underdone brownies are fudgier.
