Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Lightly grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on two sides to easily lift the brownies out later.
2. In a medium-sized mixing bowl, melt the unsalted butter. Stir in the granulated sugar until well combined.
3. To the butter and sugar mixture, crack in the two large eggs and add the vanilla extract. Whisk these ingredients together until they are fully incorporated and the mixture is light and fluffy, about 1-2 minutes.
4. Gently fold in the sourdough discard. Mix until just combined.
5. In a separate small bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Do not overmix.
6. Gently fold in the chocolate chips.
7. Pour the brownie batter into your prepared 8×8 inch baking pan and spread it evenly with a spatula. Place the pan in the preheated oven and bake for 25-30 minutes. The brownies are done when a toothpick inserted into the center comes out with moist crumbs attached, but not wet batter. The edges should look set.
8. Once baked, remove the pan from the oven and let the brownies cool completely on a wire rack in the pan. Once cooled, use the parchment paper overhang to lift them out and cut into squares.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start baking is the best way to ensure a smooth and enjoyable process. This recipe uses common pantry items, so you likely have most of them on hand already. No need for specialty flours or hard-to-find extracts; just simple, good quality ingredients will yield fantastic results.
INGREDIENTS:

- 1/2 cup (1 stick) unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup sourdough discard (unfed, 100% hydration)
- 1/2 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/4 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup chocolate chips (milk, semi-sweet, or dark)
For simple substitutions, if you only have salted butter, you can use it and reduce the added salt in the recipe to 1/8 teaspoon. Any type of chocolate chips will work beautifully here, so choose your favorite or whatever you have on hand. If you prefer a richer chocolate flavor, you can use dark cocoa powder. The sourdough discard should be unfed and at room temperature for the best incorporation into the batter.

How To Make It Step By Step With Visual Cues

Making these sourdough discard brownies is a straightforward process. Follow these steps for perfectly fudgy and chewy results every time.
- Preheat Your Oven and Prepare Your Pan: Begin by preheating your oven to 350°F (175°C). Lightly grease and flour an 8×8 inch baking pan, or line it with parchment paper, leaving an overhang on two sides to easily lift the brownies out later. This prevents sticking and makes cleanup a breeze.
- Melt the Butter and Combine with Sugar: In a medium-sized mixing bowl, melt the unsalted butter. You can do this in the microwave in short bursts or on the stovetop. Once melted, stir in the granulated sugar until well combined. The mixture should be smooth and glossy.
- Add Wet Ingredients: To the butter and sugar mixture, crack in the two large eggs and add the vanilla extract. Whisk these ingredients together until they are fully incorporated and the mixture is light and fluffy, about 1-2 minutes. This aeration helps create a tender brownie.
- Incorporate Sourdough Discard: Gently fold in the sourdough discard. Mix until just combined. Overmixing at this stage isn’t ideal, as you want to maintain some of the batter’s lightness. The discard will seamlessly blend into the wet ingredients.
- Sift and Add Dry Ingredients: In a separate small bowl, whisk together the all-purpose flour, unsweetened cocoa powder, baking soda, and salt. Sifting these dry ingredients helps prevent lumps and ensures even distribution. Gradually add the dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix; stop as soon as no streaks of flour are visible.
- Fold in Chocolate Chips: Gently fold in the chocolate chips. These will melt into delicious pockets of chocolate as the brownies bake.
- Bake the Brownies: Pour the brownie batter into your prepared 8×8 inch baking pan and spread it evenly with a spatula. Place the pan in the preheated oven and bake for 25-30 minutes. The brownies are done when a toothpick inserted into the center comes out with moist crumbs attached, but not wet batter. The edges should look set.
- Cool Before Cutting: Once baked, remove the pan from the oven and let the brownies cool completely on a wire rack in the pan. This is a crucial step for achieving that signature fudgy texture. Cutting them while warm can make them crumbly. Once cooled, use the parchment paper overhang to lift them out and cut into squares.
Easy Variations And Serving Ideas That Fit Real Life
These sourdough discard brownies are delicious on their own, but they also lend themselves beautifully to a variety of easy enhancements and serving suggestions.
For a fun twist, consider adding a handful of chopped nuts like walnuts or pecans along with the chocolate chips for extra crunch. A swirl of peanut butter or cream cheese through the batter before baking can also create a delightful marbled effect and add another layer of flavor. If you’re feeling fancy, a sprinkle of flaky sea salt on top right after they come out of the oven enhances the chocolate flavor beautifully.
When it comes to serving, these brownies are incredibly versatile. They are fantastic as a simple dessert with a glass of milk. For a more indulgent treat, serve them warm with a scoop of vanilla bean ice cream and a drizzle of chocolate sauce or caramel. They also make a wonderful addition to a dessert platter for parties or potlucks. Cut them into smaller “brookie bites” for easy grab-and-go treats. Kids especially love them with a dollop of whipped cream and some sprinkles. You can even crumble them over ice cream sundaes for a brownie sundae experience.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have a few common pitfalls. Knowing what to watch out for can help you achieve perfect sourdough discard brownies every time.
One frequent mistake is overmixing the batter once the dry ingredients are added. Overmixing develops the gluten in the flour too much, leading to tough or cakey brownies instead of the desired fudgy and chewy texture. To avoid this, mix the dry and wet ingredients only until just combined, stopping as soon as no streaks of flour are visible.
Another common issue is overbaking the brownies. If baked too long, they can become dry and crumbly. Keep a close eye on them during the last few minutes of baking. The toothpick test is your best friend here: insert a toothpick into the center, and if it comes out with moist crumbs but no wet batter, they are done. A few moist crumbs are good; a completely clean toothpick usually means they’re overdone.
Cutting the brownies too soon is another slip-up. While tempting, cutting warm brownies often results in a messy, crumbly outcome. Allowing them to cool completely in the pan helps them set up and firm, making for clean, neat squares and a much fudgier texture. Patience here truly pays off.
Finally, not using room temperature eggs and sourdough discard can affect the consistency of your batter. Cold ingredients don’t emulsify as well with the melted butter, which can lead to a less cohesive batter and potentially a less uniform texture in the final product. Try to take your eggs and discard out of the fridge about 30 minutes before you start baking.
