Ingredients

- 2/3 cup (135g) semi-sweet chocolate chips
- 1 cup (240ml) half and half or heavy cream
- 3/4 cup (165g) granulated sugar
- 6 tbsp (36g) unsweetened cocoa powder
- 1/4 tsp (1g) salt
- 2 tbsp (27g) vanilla extract
- 1 1/2 cups (180g) all-purpose flour
- 1/2 cup (48g) unsweetened cocoa powder
- 1 tsp (6g) baking soda
- 1/2 tsp (3g) salt
- 1/2 cup (113g) salted butter
- 3/4 cup (165g) granulated sugar
- 1 cup (240ml) buttermilk (substitution: 1 tbsp apple cider vinegar or lemon juice mixed with 1 cup milk of choice), at room temperature
- 2 eggs, at room temperature
- 1 tsp (4g) vanilla extract
- 1/2 cup (140g) hot fudge sauce, see recipe above
- 1/2 cup (100g) chocolate chips of choice or chopped chocolate
- Vanilla ice cream, for serving
- Flaky sea salt, for serving
Instructions
- Start by preparing the hot fudge sauce. In a medium saucepan over medium-low heat, melt the butter and chocolate chips, stirring frequently.
- Once melted, slowly whisk in the half and half (or heavy cream) until combined. Then, whisk in the sugar, cocoa powder, and salt.
- Cook over medium heat for 5 minutes, until the mixture comes to a boil. Then, reduce the heat and simmer for another 2-3 minutes, stirring frequently, until just slightly thickened.
- Remove from the heat and stir in the vanilla.
- Allow to cool and transfer it to a heat-safe jar or bowl until adding to the batter. You can store in the fridge for up to 3 weeks.
- Preheat the oven to 350F. Grease and line a standard 9x5” loaf pan with parchment paper. Set aside.
- Add the 1/2 cup (113g) butter to a saucepan over medium-high heat. Allow to melt and brown, while stirring continuously (~5-8 minutes). As the butter continues to cook, you’ll notice that it starts to foam up across the surface (after about 2 minutes). Stir frequently to prevent the milk solids from burning. Continue cooking, stirring with a spatula, until the milk solids begin to brown (the brown specks at the bottom of the pan) and the color starts to deepen. Once the brown butter reaches a deep golden amber color and smells nutty, remove from the heat and immediately pour into a large bowl. Set aside to cool slightly (about 15-20 minutes).
- In a separate medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
- Once the brown butter has slightly cooled, add the sugar and whisk to combine.
- Then beat in the eggs, buttermilk, and vanilla until combined and smooth.
- Add the dry ingredients to the wet. Fold until just combined.
- Gently fold in the 1/2 cup of the hot fudge sauce, making sure not to over-mix. Then, fold in the chocolate chips.
- Pour the batter into the prepared loaf pan. Top with extra chocolate chips if desired.
- Bake at 350F for 50-60 minutes, or until a toothpick inserted into the middle comes out clean or with moist crumbs.
- Allow to cool in the pan for 15-20 minutes, then remove the loaf from the pan and transfer to a wire cooling rack.
- Serve warm with a scoop of vanilla ice cream, an extra drizzle of the hot fudge sauce, and flaky sea salt, if desired.
