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

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 Discard

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 Together

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 come out with moist crumbs, not clean. Room temperature eggs incorporate more smoothly into the batter, creating a better emulsion with the butter and sugar. For an elevated flavor profile, try browning the butter before using it in the recipe; the nutty notes complement both the chocolate and sourdough tang beautifully. If your sourdough discard has been refrigerated, bring it to room temperature before mixing for easier incorporation. Don't skip the parchment paper overhang—it makes removing the brownies from the pan effortless and ensures clean, professional-looking edges.

Varianten und Anpassungen

These brownies are wonderfully adaptable to your preferences and pantry staples. Add 1/2 cup of chopped walnuts, pecans, or hazelnuts for a satisfying crunch and nutty depth. For a mocha twist, dissolve 1 tablespoon of instant espresso powder into the melted butter. Dark chocolate lovers can swap the semi-sweet chips for bittersweet chocolate (70% cacao) for a more intense, less sweet result. Create a swirled effect by dropping spoonfuls of peanut butter or caramel onto the batter before baking and gently swirling with a knife. For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking blend and ensure your sourdough discard is made from gluten-free flour.

Serviervorschläge

These brownies shine on their own but become truly indulgent when served warm with a scoop of vanilla ice cream or a dollop of fresh whipped cream. For an elegant dessert presentation, dust with powdered sugar and serve alongside espresso or a glass of cold milk. They're perfect for potlucks, bake sales, or as an afternoon treat with coffee. Cut them into small squares for a dessert platter, or serve larger portions as a plated dessert with raspberry coulis and fresh berries. The brownies keep well in an airtight container at room temperature for up to 3 days, or can be frozen for up to 3 months—simply thaw at room temperature and warm briefly before serving.
