These brownies are incredibly easy to make, requiring minimal effort for maximum reward. Get ready to experience brownie perfection!
Ingredients:
- 1 cup (2 sticks) unsalted butter, melted
- 1 ½ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 teaspoon salt
- 1 teaspoon vanilla extract
- 3 large eggs
- ½ cup all-purpose flour
- 1 cup sourdough discard, unfed and at room temperature
- Optional: ½ cup chocolate chips, chopped nuts, or other mix-ins
Preparing the Brownie Batter
- Melt the butter: In a large, microwave-safe bowl, melt the butter. You can do this in 30-second intervals, stirring in between, until completely melted. Alternatively, you can melt the butter in a saucepan over low heat. Be careful not to burn it!
- Combine butter, sugar, and cocoa: Once the butter is melted, remove it from the heat and whisk in the granulated sugar and cocoa powder until well combined. The mixture will be thick and slightly grainy at this point, and that’s perfectly fine. We’re building a rich, fudgy base here.
- Incorporate salt and vanilla: Add the salt and vanilla extract to the mixture. The salt enhances the chocolate flavor, and the vanilla adds a touch of warmth. Stir until everything is evenly distributed.
- Add the eggs: Now, it’s time to add the eggs, one at a time. Whisk each egg in thoroughly before adding the next. This is crucial for creating a smooth and glossy batter. Overmixing at this stage can lead to tough brownies, so be gentle but thorough.
- Mix in the flour: Gradually add the all-purpose flour to the batter, mixing until just combined. Be careful not to overmix, as this can develop the gluten in the flour and result in a cakey texture. We want fudgy, not cakey, brownies! A few streaks of flour are okay at this point.
- Incorporate the sourdough discard: This is where the magic happens! Add the sourdough discard to the batter and gently fold it in until just combined. The sourdough discard adds a subtle tang and chewiness to the brownies, making them extra special. Don’t overmix!
- Add mix-ins (optional): If you’re using any mix-ins, such as chocolate chips or chopped nuts, now is the time to add them. Gently fold them into the batter until evenly distributed. I personally love adding chocolate chips for an extra dose of chocolatey goodness.
Baking the Brownies
- Prepare the baking pan: Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan. You can also line the pan with parchment paper, leaving an overhang on the sides, for easy removal. This is my preferred method, as it ensures the brownies come out cleanly.
- Pour batter into the pan: Pour the brownie batter into the prepared baking pan and spread it evenly with a spatula. Make sure the batter reaches all the corners of the pan.
- Bake the brownies: Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with moist crumbs attached. The baking time may vary depending on your oven, so keep an eye on them. You want the center to be set but still slightly gooey.
- Cool completely: Once the brownies are baked, remove them from the oven and let them cool completely in the pan before cutting. This is the hardest part, I know! But it’s essential for achieving clean cuts and preventing the brownies from crumbling. Cooling allows the brownies to set properly and develop their fudgy texture. I usually let them cool for at least an hour, or even longer if I can resist the temptation.
Cutting and Serving
- Cut the brownies: Once the brownies are completely cool, cut them into squares. If you lined the pan with parchment paper, you can simply lift the brownies out of the pan using the overhang and then cut them on a cutting board. Use a sharp knife and wipe it clean between cuts for neat squares.
- Serve and enjoy: Serve the sourdough discard brownies and enjoy! They are delicious on their own, but you can also serve them with a scoop of vanilla ice cream, a drizzle of chocolate sauce, or a sprinkle of powdered sugar. These brownies are best enjoyed fresh, but they can also be stored in an airtight container at room temperature for up to 3 days.
Tips for Perfect Sourdough Discard Brownies
- Use room temperature sourdough discard: Make sure your sourdough discard is at room temperature before adding it to the batter. This will help it incorporate more easily and prevent the batter from becoming too cold.
- Don’t overmix the batter: Overmixing can develop the gluten in the flour and result in tough brownies. Mix the batter until just combined.
- Bake until just set: Overbaking will result in dry brownies. Bake the brownies until a toothpick inserted into the center comes out with moist crumbs attached.
- Let the brownies cool completely: Cooling allows the brownies to set properly and develop their fudgy texture.
- Experiment with mix-ins: Feel free to experiment with different mix-ins, such as chocolate chips, chopped nuts, dried fruit, or even a swirl of peanut butter.
- Adjust sugar to your preference: If you prefer a less sweet brownie, you can reduce the amount of sugar slightly.
- Use high-quality cocoa powder: The quality of the cocoa powder will affect the flavor of the brownies. Use a high-quality unsweetened cocoa powder for the best results.
- Add a pinch of espresso powder: A pinch of espresso powder can enhance the chocolate flavor of the brownies.
- Store properly: Store the brownies in an airtight container at room temperature for up to 3 days.
- Freeze for later: These brownies freeze well. Wrap them individually in plastic wrap and then place them in a freezer-safe bag. They can be frozen for up to 2 months. Thaw at room temperature before serving.
Troubleshooting Your Brownies
- Brownies are too dry: You may have overbaked the brownies. Make sure to bake them until just set. Also, make sure you are using the correct amount of flour.
- Brownies are too cakey: You may have overmixed the batter. Be careful not to overmix. Also, make sure you are not using too much flour.
- Brownies are not fudgy enough: You may have used too much flour or not enough butter. Make sure to use the correct amounts of each ingredient. Also, make sure you are not overbaking the brownies.
- Brownies are too gooey: You may have underbaked the brownies. Bake them for a few more minutes until a toothpick inserted into the center comes out with moist crumbs attached.
- Brownies are sticking to the pan: Make sure to grease and flour the baking pan thoroughly or line it with parchment paper.
Variations on Sourdough Discard Brownies
- Peanut Butter Swirl Brownies: Swirl peanut butter into the batter before baking for a nutty and delicious twist.
- Salted Caramel Brownies: Drizzle salted caramel sauce over the baked brownies for a sweet and salty treat.
- Mint Chocolate Brownies: Add mint extract to the batter and top with crushed peppermint candies after baking.
- Espresso Brownies: Add a teaspoon of espresso powder to the batter for a richer, more intense chocolate flavor.
- Double Chocolate Brownies: Use both unsweetened cocoa powder and melted dark chocolate in the batter for an extra chocolatey experience.
Enjoy your baking!
