Preheat oven to 350 degrees and spray the loaf pan with baking spray.

In a large bowl, mix together the brownie mix, 1 jar of hot fudge sauce, 3 large eggs, and canola oil until combined.

Pour the mixture into the loaf pan and bake for 55-65 minutes or until a toothpick comes out clean.

Allow to cool completely before moving to a wire rack.

Heat up the second jar of hot fudge sauce and pour it over the loaf.

Allow the hot fudge to harden before cutting and enjoying.
