Fudgy Sourdough Discard Brownies

These ultra-fudgy brownies combine melted dark chocolate, butter, and neutral oil to create a rich base. Incorporating sourdough discard adds a subtle tang that complements the deep cocoa flavor. Two types of sugar and eggs produce a glossy, thick batter that's folded gently with flour, cocoa powder, and sea salt. Finished with flaky sea salt on top, these squares offer the perfect balance of sweet and salty in every bite.

Baked until edges set but the center remains slightly soft, they deliver a moist, chewy texture. Ideal for an easy yet impressive dessert, they can be customized by adding extra chocolate chunks or swapping sugars for nuanced flavors. Store airtight to maintain freshness and pair wonderfully with espresso or red wine.

  • Chocolate & Fats: 170 g (6 oz) dark chocolate (60–70% cocoa), chopped; 115 g (½ cup) unsalted butter, cubed; 60 ml (¼ cup) neutral oil (e.g., canola or vegetable)
  • Sugars: 200 g (1 cup) granulated sugar; 100 g (½ cup) light brown sugar, packed
  • Eggs & Sourdough: 2 large eggs, at room temperature; 1 large egg yolk; 120 g (½ cup) sourdough discard, unfed and at room temperature; 1 tsp pure vanilla extract
  • Dry Ingredients: 60 g (½ cup) all-purpose flour; 35 g (⅓ cup) unsweetened Dutch-process cocoa powder; ½ tsp fine sea salt
  • Topping: Flaky sea salt, for sprinkling

Instructions

Step 1: Prepare the pan
Preheat oven to 175°C (350°F). Line a 20x20 cm (8x8 inch) baking pan with parchment, leaving overhang on two sides.
Step 2: Melt chocolate and butter
In a heatproof bowl set over a pan of simmering water, melt chocolate and butter together, stirring until smooth. Remove from heat and whisk in oil.
Step 3: Add sugars
Whisk in both sugars until glossy and combined.
Step 4: Incorporate eggs
Add eggs and egg yolk one at a time, whisking well after each addition. Whisk vigorously for 1–2 minutes until mixture is thick and shiny.
Step 5: Add sourdough and vanilla
Stir in sourdough discard and vanilla extract until fully incorporated.
Step 6: Fold in dry ingredients
Sift in flour, cocoa powder, and fine sea salt. Fold gently with a spatula until just combined; do not overmix.
Step 7: Transfer to pan
Pour batter into prepared pan and smooth the top. Sprinkle generously with flaky sea salt.
Step 8: Bake
Bake for 28–32 minutes, or until the edges are set but the center is still slightly soft—a toothpick inserted should come out with moist crumbs.
Step 9: Cool and serve
Cool completely in the pan on a wire rack before lifting out and slicing into squares.

Zusatztipps für die Zubereitung

The key to perfectly fudgy brownies is not overbaking. Watch carefully during the final minutes and remove them when the edges are set but the center still has a slight jiggle. They'll continue to firm up as they cool. Use room temperature eggs and sourdough discard for better incorporation and a smoother batter. When folding in the dry ingredients, use gentle strokes and stop as soon as you no longer see streaks of flour—overmixing develops gluten and can lead to cakey rather than fudgy brownies. For the cleanest cuts, refrigerate the cooled brownies for 30 minutes before slicing with a sharp knife wiped clean between cuts.

Varianten und Anpassungen

For extra decadence, fold in 100 g (⅔ cup) chopped dark chocolate or chocolate chips before baking for pockets of melted chocolate throughout. Swap brown sugar for coconut sugar for a deeper caramel note that pairs beautifully with the chocolate. You can also experiment with different toppings: try crushed freeze-dried raspberries mixed with the sea salt, or sprinkle with espresso powder for an intensified mocha flavor. For a nut variation, fold in toasted walnuts or pecans, though note this changes the allergen profile. If you prefer less tang, reduce the sourdough discard to 80 g and increase the flour by 20 g.

Serviervorschläge

These brownies are spectacular on their own, but they also shine when served slightly warm with a scoop of vanilla ice cream or a dollop of lightly sweetened whipped cream. They pair beautifully with espresso or a glass of red wine for an elegant dessert moment. For a more casual presentation, cut them into bite-sized pieces and serve as part of a dessert platter. Store brownies airtight at room temperature for up to 3 days, or freeze individual squares wrapped in plastic wrap and stored in a freezer bag for up to 3 months—perfect for impromptu sweet cravings.
