For the Brownie Batter:

• Sourdough discard (unfed starter): Adds moisture and a subtle tang, enhancing the texture and flavor.

• All-purpose flour: Provides structure and helps achieve the perfect chewiness.
• Eggs: Essential for a chewy, fudgy texture and binding the ingredients together.
• Butter or coconut oil: Adds richness and moisture, making the brownies soft yet dense.
• Brown sugar & granulated sugar: A combination of sugars creates a perfect balance of sweetness and chewiness.
• Vanilla extract: Deepens the chocolate flavor while adding a touch of warmth.
• Espresso powder (optional): Intensifies the chocolate flavor without making the brownies taste like coffee.
• Salt: Balances and enhances the sweetness while bringing out the deep chocolate notes.

How to Make Sourdough Discard Brownies

Follow these simple steps to make rich, fudgy sourdough discard brownies with minimal effort!

1. Melt the Chocolate & Mix Wet Ingredients

• In a heatproof bowl, melt butter and dark chocolate until smooth. Stir in 30-second intervals using a double boiler or microwave, stirring between each.
• Whisk in sourdough discard, eggs, brown sugar, granulated sugar, and vanilla extract until fully combined and smooth.

2. Add the Dry Ingredients

• Sift flour, cocoa powder (if using), salt, and espresso powder (optional) to ensure a lump-free batter.
• Gently mix the ingredients using a spatula until combined—don’t overmix! Overmixing can lead to dense, cakey brownies instead of a fudgy texture.

3. Bake the Brownies

• Pour the batter into a lined 8×8-inch baking pan and spread it evenly.
• Bake at 325°F-350°F (160°C-175°C) for 25-30 minutes, or until the edges are set but the center is still slightly soft. Insert a toothpick into the center; it should come out with slightly moist crumbs.

4. Cool & Slice

• Let the brownies cool completely in the pan before slicing—this helps them set properly and achieve a perfect fudgy texture.
• Slice into clean squares using a sharp knife, wiping the blade between cuts for neat edges.
• Serve and enjoy your chewy, decadent sourdough discard brownies!

Tips, Variations & Serving Suggestions

Tips for the Best Brownies:

Want perfectly rich and fudgy sourdough discard brownies every time? Follow these expert tips:

• Use an active sourdough discard: Fresh discard gives the best texture, while older discard can be too acidic.
• For extra fudgy brownies, slightly underbake them. When removed from the oven, the center should be slightly soft. Let them cool completely for the best consistency.
• Sift the cocoa powder and flour: This prevents lumps and ensures a smooth, even batter.
