The beauty of these brownies lies in the harmony between rich chocolate and the subtle fermented notes from sourdough discard. Unlike traditional brownies, the addition of sourdough starter creates a uniquely dense crumb that's both fudgy and tender. Each bite reveals pockets of melted chocolate chunks, making every square a decadent treat that's perfect for any occasion, from casual family desserts to impressive dinner party finales.

Ingredients

• Chocolate & Cocoa: 120 g (4 oz) bittersweet chocolate, chopped; 60 g (2 oz) milk chocolate, chopped; 30 g (1/4 cup) unsweetened Dutch-process cocoa powder
• Fats: 115 g (1/2 cup) unsalted butter, cubed
• Sugar: 200 g (1 cup) granulated sugar; 50 g (1/4 cup) light brown sugar, packed
• Sourdough & Liquids: 120 g (1/2 cup) sourdough discard (unfed); 2 large eggs, at room temperature; 1 tsp pure vanilla extract
• Dry Ingredients: 80 g (2/3 cup) all-purpose flour; 1/2 tsp fine sea salt
• Chocolate Mix-ins: 60 g (1/3 cup) semi-sweet chocolate chips or chunks

Instructions

Step 1: Prepare the Pan

Preheat your oven to 350°F (175°C). Line an 8-inch (20 cm) square baking pan with parchment paper, leaving some overhang for easy removal.

Step 2: Melt the Chocolate Base

In a heatproof bowl, combine the bittersweet chocolate, milk chocolate, cocoa powder, and butter. Melt together over a saucepan of simmering water or in the microwave in 30-second bursts, stirring until smooth. Let cool slightly.

Step 3: Whisk the Eggs and Sugar

In a large bowl, whisk together the sugars, eggs, and vanilla extract until pale and thick, about 2–3 minutes.

Step 4: Add Sourdough to Chocolate

Whisk the sourdough discard into the chocolate mixture until fully incorporated.

Step 5: Combine Wet Ingredients

Add the chocolate mixture to the egg-sugar mixture and mix gently until combined.

Step 6: Add Dry Ingredients

Sift in the flour and salt. Fold in gently with a spatula until just combined; do not overmix.

Step 7: Fold in Chocolate Chips

Gently fold in the chocolate chips or chunks.

Step 8: Transfer to Pan

Pour the batter into the prepared pan and smooth the top.

Step 9: Bake

Bake for 28–32 minutes, or until the edges are set and the center is just slightly wobbly. Do not overbake for a chewy center.

Step 10: Cool and Slice

Cool completely in the pan on a wire rack before lifting out and slicing into squares.

Zusatztipps für die Zubereitung

For the fudgiest texture, avoid overbaking these brownies. The center should still have a slight wobble when you remove them from the oven, as they will continue to set as they cool. For extra chew, chill the brownies for at least 1 hour before slicing. Using room temperature eggs helps create a smooth, emulsified batter that bakes more evenly. When melting chocolate, ensure no water gets into the mixture, as this can cause the chocolate to seize. A clean, sharp knife dipped in hot water and wiped dry between cuts will give you perfectly clean slices.

Varianten und Anpassungen

Add 1/2 cup chopped toasted walnuts or pecans for crunch and a nutty complement to the chocolate. Dark chocolate can be substituted for bittersweet if desired for a more intense chocolate flavor. For a flavor twist, add 1/2 teaspoon of espresso powder to the chocolate mixture to enhance the chocolate notes. Swap the semi-sweet chocolate chips for white chocolate chips for a contrasting sweetness, or use a combination of both. For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking blend.

Serviervorschläge

Serve with a scoop of vanilla ice cream for an indulgent dessert that balances the rich chocolate with cool creaminess. Dust with powdered sugar or cocoa powder for an elegant presentation. These brownies pair beautifully with fresh raspberries or strawberries, which cut through the richness with their bright acidity. For a grown-up treat, serve alongside espresso or a glass of red wine. They're also perfect for gifting when cut into squares and wrapped in parchment paper tied with twine.
