Preheat your oven to 350°F (175°C). Grease and flour a loaf pan (9×5 inches) or line it with parchment paper for easy removal.
Make the Batter:
In a large mixing bowl, whisk together the flour, cocoa powder, baking powder, and salt. Set aside.
In another bowl, mix the melted butter with the granulated sugar and brown sugar until smooth. Add the eggs and vanilla extract, and mix until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Stir in the milk, making the batter smooth and slightly thick.
Add the Hot Fudge:
Gently fold in 1 cup of hot fudge sauce into the batter, being careful not to overmix. The fudge will create pockets of gooey richness throughout the bread.
Bake the Brownie Bread:
Pour the batter into the prepared loaf pan and smooth the top with a spatula. If desired, sprinkle the chopped chocolate or chocolate chips on top for extra chocolatey goodness.
Bake for 45-50 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay due to the fudgy texture).
Serve:
Let the brownie bread cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. Once cooled, drizzle with extra hot fudge sauce for an extra indulgent treat. Slice and serve.
