Sourdough Discard Brownies Ingredients
For the Brownies
• Butter – Adds richness and moisture; use unsalted butter for better control over salt levels.
• Semi-Sweet Chocolate Chips – Main flavor source; opt for chips with 60% cocoa for the best balance of sweetness and taste.
• Vanilla Extract – Enhances overall flavor; substitute with almond extract for a delightful twist.
• Dutched Cocoa Powder – Contributes to the chocolate intensity; regular cocoa can work too but will alter the flavor slightly.
• Eggs – Provides structure and moisture; make sure they’re at room temperature for optimal results.
• Brown Sugar – Adds sweetness with a hint of caramel flavor; can be replaced with granulated sugar, though this reduces flavor depth.
• Granulated Sugar – Complements the brown sugar; consider reducing the total sugar for a less sweet treat.
• Sourdough Discard – The key ingredient that brings a unique tangy flavor and adds moisture; alternately, use equal parts yogurt or buttermilk.
• All-Purpose Flour – Essential for brownie structure; gluten-free flour can be used for a gluten-free option.
• Salt – Balances sweetness and enhances flavors; feel free to omit for dietary restrictions.
Step‑by‑Step Instructions for Sourdough Discard Brownies
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (176°C). While the oven warms up, line a 9″x9″ baking dish with parchment paper, allowing some overhang for easy removal later. This step ensures your Sourdough Discard Brownies will bake evenly and not stick to the pan.
Step 2: Melt Butter and Chocolate
In a medium saucepan, melt 1 cup of unsalted butter over low heat. Once the butter is melted, stir in 1 cup of semi-sweet chocolate chips, along with 1 teaspoon of vanilla extract and ½ cup of dutched cocoa powder. Keep stirring until the mixture is smooth and homogeneous, then remove from heat and let cool for a few minutes.
Step 3: Beat the Sugars and Eggs
In a large mixing bowl, combine 2 eggs with 1 cup of brown sugar and ½ cup of granulated sugar. Use an electric mixer to beat this mixture on medium speed for about 7-10 minutes, or until it becomes light and creamy. This step is key for adding air to your Sourdough Discard Brownies, making them fudgy yet soft.
Step 4: Combine Ingredients
Gently mix in the cooled chocolate and butter mixture along with 1 cup of sourdough discard into the sugar and egg blend. Use a low speed to combine until just incorporated. The batter should have a rich chocolate color, and you’ll start to feel the unique tang from the sourdough coming through.
Step 5: Fold in Dry Ingredients
Now, add 1 cup of all-purpose flour and a pinch of salt to the wet mixture. Carefully fold these dry ingredients into the batter with a spatula until just combined. Be cautious not to overmix; the goal is to maintain the thick, fudgy consistency that makes these Sourdough Discard Brownies so irresistible.
Step 6: Pour and Smooth the Batter
Pour your brownie batter into the prepared baking dish, spreading it evenly using a spatula. Smooth the top for an even bake and prevent any surface bumps. The thick batter should hold its shape, giving you a perfect base to work with for the fudgy brownies.
Step 7: Bake the Brownies
Place the baking dish in the preheated oven and bake for 35-40 minutes. Check for doneness by inserting a toothpick into the center; it should come out with a few moist crumbs for that perfect fudgy texture. Keep an eye on them as ovens can vary!
Step 8: Cool and Slice
Once baked, allow the Sourdough Discard Brownies to cool completely in the pan on a wire rack. When cool, use the parchment overhang to lift the brownies out. Slice into squares and serve them fresh or store them for later. Their rich, fudgy interior will have everyone coming back for more!

Sourdough Discard Brownies Recipe FAQs
What type of sourdough discard should I use?
Absolutely! You can use any type of sourdough discard, whether it’s white, whole wheat, or rye. Just make sure it’s active and bubbly for the best flavor. If your discard has a strong smell, it might be best to use a fresher batch!
How should I store my brownies after baking?

What if my brownies are too cakey instead of fudgy?
If your brownies turn out too cakey, it usually means they were overbaked. Make sure to check them a few minutes early; they should come out with a few moist crumbs clinging to the toothpick.
