2-3tablespoonsmilk or heavy cream
1/4teaspoonvanilla extract
Instructions
Preheat Oven and Prepare Pan:
Preheat your oven to 350°F (175°C). Grease and flour a 9x5-inch loaf pan or line it with parchment paper.
Dry Ingredients:
In a medium bowl, sift together the flour, cocoa powder, baking soda, and salt. Set aside.
Cream Butter and Sugar:
In a large bowl, using an electric mixer, cream together the softened butter and granulated sugar until light and fluffy. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
Combine with Dry Ingredients:
Alternately add the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix until just combined. Do not overmix.
Add Hot Fudge Sauce:
Gently fold in 1/2 cup of hot fudge sauce into the batter. If the sauce is too thick, gently warm it up to make it more pourable.
Pour Batter into Pan:
Pour the batter into the prepared loaf pan. Drop spoonfuls of additional hot fudge sauce on top of the batter and use a knife to swirl it through for a marbled effect.
Bake:
Bake for 55-65 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
Cool and Glaze:
Allow the bread to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely. If using the glaze, whisk together the powdered sugar, milk (or cream), and vanilla extract until smooth, and drizzle over the cooled bread.
Serve:
Slice and serve the bread with an extra drizzle of hot fudge sauce on top if desired.
