Preheat your oven to 350°F (175°C) to ensure it’s ready for an even bake.

In a medium mixing bowl, add the brownie mix, hot fudge sauce, eggs, and vegetable oil. Stir until the batter is smooth and glossy, ensuring everything is well combined.

Lightly grease your loaf pan with vegetable oil or non-stick spray. Pour the batter in, filling it about 3/4 full to leave room for rising.

Place the loaf pan in the oven and bake for about 45 minutes. The bread is done when a toothpick inserted into the center comes out clean or with a few moist crumbs.

Let the bread cool in the pan on a wire rack. Once fully cooled, loosen the edges with a knife and remove it from the pan to slice and serve.
