The beauty of these brownies lies in their simplicity and the clever use of sourdough discard. Unlike traditional brownies, the addition of unfed starter brings a subtle tanginess that enhances the chocolate without overwhelming it. The sea salt flakes scattered on top aren't just garnish—they create little bursts of salty contrast that make each bite more complex and satisfying. This recipe proves that sourdough discard is far too valuable to throw away, transforming it into a dessert that's both economical and absolutely delicious.

Ingredients

• Wet Ingredients: 1/2 cup (115 g) unsalted butter, melted; 1 cup (200 g) granulated sugar; 2 large eggs, room temperature; 1/2 cup (120 g) sourdough discard (unfed, 100% hydration); 1 tsp pure vanilla extract
• Dry Ingredients: 3/4 cup (90 g) all-purpose flour; 1/2 cup (50 g) unsweetened cocoa powder; 1/2 tsp baking powder; 1/4 tsp fine sea salt
• Mix-ins & Topping: 1/2 cup (90 g) semi-sweet chocolate chips or chopped chocolate; 1/2 tsp flaky sea salt (for topping)

Instructions

Step 1: Prepare the pan and preheat

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

Step 2: Mix wet ingredients

In a large bowl, whisk together melted butter and sugar until glossy and well combined. Add eggs, one at a time, whisking after each addition until the mixture is thick and lighter in color.

Step 3: Add sourdough and vanilla

Stir in the sourdough discard and vanilla extract until fully incorporated.

Step 4: Combine dry ingredients

In a separate bowl, sift together the flour, cocoa powder, baking powder, and fine sea salt.

Step 5: Fold dry into wet

Add the dry ingredients to the wet mixture, folding gently with a spatula until just combined. Do not overmix.

Step 6: Add chocolate

Fold in the chocolate chips or chopped chocolate.

Step 7: Prepare for baking

Pour the batter into the prepared baking pan and smooth the top. Sprinkle evenly with flaky sea salt.

Step 8: Bake

Bake for 28–32 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter).

Step 9: Cool and serve

Let the brownies cool completely in the pan before lifting out and slicing into squares.

Zusatztipps für die Zubereitung

For the fudgiest texture, avoid overbaking—the toothpick should have moist crumbs, not come out completely clean. Using room temperature eggs helps them incorporate more smoothly into the batter, creating a better texture. When folding in the dry ingredients, use a gentle hand and stop as soon as no flour streaks remain; overmixing can lead to tough, cakey brownies instead of fudgy ones. For extra richness, try browning the butter before adding it to the sugar—this adds a nutty, caramelized depth. Make sure your sourdough discard is at 100% hydration for consistent results.

Varianten und Anpassungen

These brownies are endlessly customizable. Add 1/2 cup chopped walnuts or pecans for crunch and a classic brownie texture. For a double chocolate version, mix in white chocolate chips alongside the semi-sweet ones. Try substituting the vanilla extract with peppermint or espresso powder for flavor variations. Make them gluten-free by using a 1:1 gluten-free flour blend. For a vegan adaptation, replace eggs with flax eggs and use plant-based butter and chocolate. You can also swirl in 1/4 cup of peanut butter or Nutella before baking for a marbled effect.

Serviervorschläge

These brownies are perfect on their own, but they truly shine when served warm with a scoop of vanilla ice cream melting over the top. For an elegant dessert, dust with powdered sugar and serve with fresh raspberries or strawberries to cut through the richness. They pair beautifully with a strong cup of coffee or a glass of cold milk. For a more indulgent treat, drizzle with salted caramel sauce or top with whipped cream. These brownies also make excellent ice cream sandwiches—just sandwich your favorite ice cream between two brownie squares and freeze.
