- 2 teaspoons vanilla extract

Notes & Substitutions
Using sourdough discard in recipes like these brownies is a fantastic way to minimize waste and add a unique depth of flavor to your baked goods, as highlighted in various sourdough discard recipes and uses.
Use unfed sourdough discard straight from the fridge; it won’t impact the leavening here. Dutch-processed cocoa creates a darker, less acidic flavor, while natural cocoa is fruitier. For chocolate, high-quality semi-sweet chips, chunks, or chopped bars all work well. You can substitute unsalted butter with an equal amount of neutral oil or vegan butter. Adjust sugar by using all granulated for a chewier brownie or all brown for a softer texture. The extra egg yolk adds richness and contributes to that desirable fudgy texture.
Equipment
Gather your basic baking tools for these sourdough discard brownies. You will need a 9×9 inch baking dish, parchment paper, a small saucepan, a large mixing bowl, an electric mixer (handheld or stand mixer), and a spatula.
Instructions
Preheat your oven to 350°F (176°C). Line a 9″ x 9″ baking dish with parchment paper, leaving an overhang on two sides to help with removal.
In a small saucepan over low heat, melt the unsalted butter. Remove from heat and add the semi-sweet chocolate chips, vanilla extract, and Dutch-processed cocoa powder. Stir these ingredients until the chocolate chips fully melt and the mixture becomes smooth and glossy. Set the saucepan aside to cool slightly.
In a large mixing bowl, combine the two large eggs, the extra egg yolk, granulated sugar, and dark brown sugar. Beat with an electric mixer on medium-high speed for 7-10 minutes until the mixture is very pale, thick, and fluffy. This step is crucial for achieving that shiny, crackly top on your sourdough discard brownies.
Add the 1/2 cup of sourdough starter discard and the cooled chocolate mixture to the egg and sugar mixture. Beat on low speed until just combined. Next, add the all-purpose flour and salt. Use a spatula to gently fold these dry ingredients into the wet mixture until just combined. Be careful not to overmix; the batter will be very thick.
Pour the thick brownie batter into your prepared baking dish and use the spatula to smooth the top evenly. Bake for 35-40 minutes. The brownies are done when a toothpick inserted into the center comes out with moist crumbs, but not wet batter.
Allow the brownies to cool completely in the pan on a wire rack after they come out of the oven. This is vital for the fudgiest texture and clean slices. Once completely cool, lift the brownies from the pan using the parchment paper overhang and cut into squares. Enjoy your delicious sourdough discard brownies!
Pro Tips for Perfect Sourdough Discard Brownies
- Do not overmix the batter. Overmixing develops gluten, leading to tougher brownies. Stir until just combined.
- Achieve shiny tops by beating the eggs and sugars thoroughly until pale and thick. This incorporates air and creates that desirable crust.
- Avoid overbaking for the fudgiest results. The center should still look slightly underdone when you pull them from the oven.
- Cool brownies completely before slicing. Warm brownies are crumbly; cooling sets their fudgy texture for clean, neat cuts.
- Use parchment paper to easily remove the entire slab of brownies from the pan without sticking.
- Bloom cocoa powder for deeper flavor. Mix the cocoa with the hot melted butter before adding other ingredients.

Frequently Asked Questions (FAQ)
Does sourdough discard make brownies sour?
No, using unfed sourdough discard in this recipe does not make the brownies taste sour. It simply adds a subtle tang and moisture without a strong fermented flavor.
Can I use active sourdough starter?
While unfed discard is recommended, you can use active sourdough starter. However, be aware it might slightly alter the texture due to its leavening power.
How do I tell if my brownies are done baking?
Insert a toothpick into the center of the brownies. It should come out with moist crumbs attached, but not wet batter. The edges will look set.
What’s the difference between Dutch-processed and natural cocoa?
Dutch-processed cocoa is treated to reduce acidity, resulting in a darker color and milder, less bitter chocolate flavor. Natural cocoa is more acidic and has a fruitier, sharper chocolate taste.
Can I use only one type of sugar?
Yes, you can use all granulated sugar for a chewier brownie, or all brown sugar for a softer, more moist result. The combination of both sugars yields the best texture for these sourdough discard brownies.
Can I add other mix-ins to the batter?
Absolutely! Feel free to incorporate up to 1 cup of chopped nuts, extra chocolate chips, or even dried fruit into the batter.
Why is an extra egg yolk used?
The extra egg yolk adds richness and fat to the batter, contributing to a more dense, fudgy, and moist texture. It also helps achieve that desirable crackly top.
