This recipe combines the tang of sourdough discard with the richness of chocolate, creating the perfect fudgy brownie. Walnuts are optional but add a nice crunch and flavor contrast!

Ingredients:

  • 1/2 cup (115g) unsalted butter, melted

  • 1 cup (200g) granulated sugar

  • 2 large eggs

  • 1/2 cup (120g) sourdough discard (unfed, at room temperature)

  • 1 teaspoon vanilla extract

  • 1/2 cup (65g) all-purpose flour

  • 1/3 cup (35g) unsweetened cocoa powder (I use Hershey's)

  • )1/2 teaspoon baking powder

  • 1/4 teaspoon salt

  • 1/2 cup (90g) semi-sweet chocolate chips (or more if you like it extra chocolaty)

  • 1/2 cup (60g) chopped walnuts (optional)

Instructions:

Step 1: Preheat the Oven and Prepare the Pan

  • Preheat your oven to 350°F (175°C).

  • Grease a 9x9-inch square baking pan or line it with parchment paper for easy removal later.

Step 2: Mix the Wet Ingredients

  • In a large bowl, melt the butter in the microwave or on the stovetop.

  • Once melted, whisk the granulated sugar into the butter until smooth.

  • Add the eggs, one at a time, beating well after each addition.

  • Stir in the sourdough discard and vanilla extract until fully combined.

Step 3: Add the Dry Ingredients

  • In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt.

  • Gradually add the dry ingredients to the wet ingredients, mixing until just combined. The batter will be thick.

Step 4: Add the Chocolate Chips and Walnuts

  • Gently fold in the chocolate chips and chopped walnuts (if using). The chocolate chips will melt slightly into the batter, adding extra gooeyness.

Step 5: Bake the Brownies

  • Pour the brownie batter into the prepared baking pan, spreading it evenly with a spatula.

  • Bake for 20-25 minutes, but check with a toothpick. Insert it into the center of the brownies—if it comes out with just a few moist crumbs (not wet batter), they are done.

  • The brownies should still be soft and fudgy in the center.

Step 6: Cool and Slice

  • Allow the brownies to cool completely in the pan on a wire rack. Once cool, lift them out using the parchment paper (if used) and cut into squares.

Tips for Perfect Fudgy Brownies:

  • Don’t overbake: For fudgy brownies, err on the side of underbaking slightly. If the toothpick comes out with a few moist crumbs, that’s perfect.

  • Use room-temperature eggs and sourdough discard for better incorporation into the batter.

  • Customize: You can mix in additional mix-ins like peanut butter chips, toffee bits, or marshmallows if you want to play around with flavors.

These fudgy sourdough brownies are rich, decadent, and have a slight tang from the sourdough discard, giving them a unique flavor. The chocolate chips create gooey pockets of chocolate, and the optional walnuts add a delightful crunch. Perfect for satisfying your chocolate cravings! Enjoy!
