Ingredients
Instructions
1. Preheat your oven to 350 F (175 C). Lightly grease an 8×8 inch square baking pan or line it with parchment paper, leaving an overhang on two sides to easily lift the brownies out later.
2. In a large mixing bowl, melt the unsalted butter. Add the granulated sugar to the warm butter and whisk until well combined. Crack in the two large eggs, one at a time, whisking well after each addition until fully incorporated. Stir in the vanilla extract and the sourdough discard until the mixture is smooth and uniform.
3. In a separate medium bowl, combine the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Use a whisk to thoroughly mix these dry ingredients together.
4. Gradually add the dry ingredient mixture to the wet ingredient mixture in the large bowl. Using a spatula or wooden spoon, mix until just combined. Do not overmix.
5. Gently fold in the chocolate chunks or chips into the brownie batter. Distribute them evenly throughout the batter.
6. Pour the brownie batter into your prepared 8×8 inch baking pan. Use your spatula to spread the batter evenly to the corners of the pan. 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, but not wet batter.
7. Once baked, remove the brownies from the oven and place the pan on a wire rack to cool completely. Allow them to cool for at least 20-30 minutes, or even longer, to help them set up and become perfectly fudgy. If you used parchment paper, you can lift the cooled brownies out of the pan and onto a cutting board for easy slicing. Cut into squares and serve.

Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start baking is a great way to ensure a smooth and enjoyable process. This recipe uses common pantry staples, making it accessible and convenient. You likely have most of these items on hand already, which means you can decide to bake these brownies on a whim. The quality of your ingredients, especially the chocolate, will make a noticeable difference in the final flavor of your brownies. Opt for good quality chocolate chunks or a chocolate bar that you can chop yourself for the best results.
INGREDIENTS:

- 1/2 cup unsalted butter, melted
- 1 cup granulated sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup sourdough discard (unfed, at room temperature)
- 1/2 cup all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 cup chocolate chunks or chips
If you don’t have unsalted butter, you can use salted butter and simply omit the added salt in the recipe. For the chocolate chunks, feel free to use your favorite type of chocolate – semi-sweet, milk, or even dark chocolate will work beautifully. If you only have chocolate chips, those are a perfectly fine substitute for chunks, though chunks tend to give a more varied texture. Ensure your sourdough discard is at room temperature to help it incorporate smoothly into the batter. For the cocoa powder, natural unsweetened cocoa powder is generally preferred for brownies as it contributes to a richer chocolate flavor.
Time Needed From Start To Finish
One of the best aspects of this sourdough brownie recipe is how quickly it comes together, making it perfect for those times when you need a delicious dessert without a long wait. The hands-on preparation time is minimal, allowing you to get these brownies into the oven in no time.
- Preparation Time: 15 minutes
- Baking Time: 25-30 minutes
- Cooling Time: 20-30 minutes (recommended for best fudgy texture)
- Total Time: Approximately 60-75 minutes
While the brownies are technically ready to eat right out of the oven, allowing them to cool slightly helps them set up and achieve that desirable fudgy texture. If you’re in a hurry, you can certainly enjoy them warm, but for cleaner cuts and a more stable brownie, a little patience during the cooling phase goes a long way.
How To Make It Step By Step With Visual Cues

Making these sourdough chocolate chunk brownies is a straightforward process that yields incredibly delicious results. Follow these simple steps for a perfect batch every time.
- Prepare Your Baking Pan: Begin by preheating your oven to 350°F (175°C). Lightly grease an 8×8 inch square baking pan or line it with parchment paper, leaving an overhang on two sides to easily lift the brownies out later. This step ensures your brownies won’t stick and makes for easy removal and cleanup.
- Melt the Butter and Combine Wet Ingredients: In a large mixing bowl, melt the unsalted butter. You can do this in the microwave in short bursts or on the stovetop. Once melted, add the granulated sugar to the warm butter and whisk until well combined. The mixture should look slightly glossy. Then, crack in the two large eggs, one at a time, whisking well after each addition until fully incorporated. Stir in the vanilla extract and the sourdough discard until the mixture is smooth and uniform.
- Whisk Together Dry Ingredients: In a separate medium bowl, combine the all-purpose flour, unsweetened cocoa powder, baking powder, and salt. Use a whisk to thoroughly mix these dry ingredients together. This helps to distribute the leavening agent and cocoa powder evenly, preventing lumps in your final batter.
- Combine Wet and Dry Mixtures: Gradually add the dry ingredient mixture to the wet ingredient mixture in the large bowl. Using a spatula or wooden spoon, mix until just combined. Be careful not to overmix the batter; overmixing can lead to tough brownies. Stop mixing as soon as you no longer see streaks of dry flour.
- Fold in the Chocolate Chunks: Gently fold in the chocolate chunks or chips into the brownie batter. Distribute them evenly throughout the batter so that every bite of brownie has delicious pockets of chocolate.
- Transfer to Baking Pan and Bake: Pour the brownie batter into your prepared 8×8 inch baking pan. Use your spatula to spread the batter evenly to the corners of the pan. 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, but not wet batter. Avoid overbaking, as this can result in dry brownies.
- Cool Before Slicing: Once baked, remove the brownies from the oven and place the pan on a wire rack to cool completely. Allowing them to cool for at least 20-30 minutes, or even longer, will help them set up and become perfectly fudgy. If you used parchment paper, you can lift the cooled brownies out of the pan and onto a cutting board for easy slicing. Cut into squares and serve.
Easy Variations And Serving Ideas That Fit Real Life
These sourdough chocolate chunk brownies are fantastic on their own, but they also lend themselves beautifully to a few simple variations and serving suggestions that can elevate them for any occasion. These ideas are designed to be easy and practical, fitting into a busy lifestyle.
For a fun twist, consider adding a sprinkle of flaky sea salt over the top of the brownies immediately after they come out of the oven. The salt enhances the chocolate flavor and provides a delightful contrast. You could also swirl in a tablespoon or two of peanut butter or a nut butter of your choice into the batter just before baking for a marbled effect and an extra layer of flavor. If you’re a fan of nuts, a half cup of chopped walnuts or pecans can be folded into the batter along with the chocolate chunks for added crunch.
When it comes to serving, these brownies are incredibly versatile. For a simple dessert, serve them as is with a glass of milk. To make them a bit more indulgent, warm them slightly and serve with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of chocolate sauce. They also make an excellent addition to a dessert platter for parties or potlucks. Cut them into smaller, bite-sized squares for easy grab-and-go treats. For a kid-friendly option, consider adding a handful of mini marshmallows to the top during the last 5-10 minutes of baking for a s’mores-like brownie. These brownies are also perfect for lunchbox treats or an afternoon pick-me-up with a cup of coffee or tea.
Common Slip-Ups And How To Avoid Them
Even with a straightforward recipe like these sourdough brownies, a few common mistakes can impact the final outcome. Knowing what to look out for can help you achieve perfect fudgy brownies every time.
One of the most frequent slip-ups is overmixing the batter. Once you combine the wet and dry ingredients, mix only until no streaks
