This double chocolate hot fudge brownie bread combines the rich flavor of a fudgy brownie with the shape and sliceability of a loaf. Swirled with hot fudge and bursting with chocolate, it’s moist, dense, and deeply satisfying.
1/2 cup (1 stick) unsalted butter
4 oz semi-sweet or dark chocolate, chopped
3/4 cup granulated sugar
1/4 cup brown sugar (optional)
2 large eggs
1 tsp vanilla extract
1/3 cup unsweetened cocoa powder
1/2 cup all-purpose flour
1/2 tsp baking powder
1/4 tsp salt
1/2 cup hot fudge sauce (plus more for topping)
Optional: 1/2 cup chocolate chips or chunks
Preheat oven to 350°F (175°C). Grease and line a 9×5 loaf pan with parchment.
Melt butter and chocolate until smooth. Let cool slightly.
Stir in sugars, then eggs and vanilla. Whisk until glossy.
Sift in cocoa powder, flour, salt, and baking powder. Stir until just combined.
Fold in chocolate chips, if using.
Pour half of the batter into pan, swirl with half of the hot fudge. Add remaining batter and top with remaining fudge.
Bake 50–60 minutes, or until a toothpick comes out with moist crumbs.
Cool in pan before slicing.
Don’t overbake — the center should remain moist.
Store covered at room temp for 3 days or freeze for longer storage.
Swirl in peanut butter or caramel for fun variations.
