Coat the loaf pan with Pam baking spray and set the oven temperature to 350 degrees.
In a big basin, combine the brownie mix with the oil, 3 big eggs, and 1 jar of hot fudge sauce.
Using a toothpick, test whether the mixture is done after 55 to 65 minutes in the oven. Transfer to the loaf pan.
After cooling, transfer to a wire rack.
Pour the loaf with the heated fudge sauce from another jar.
After the hot fudge has cooled, cut it into pieces and savor!
