Ingredients
List of Ingredients
- 1 cup (240g) unsalted butter, melted
- 1 cup (200g) granulated sugar
- 1 cup (100g) packed brown sugar
- 1 cup (240g) sourdough discard
- 4 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 1 cup (125g) all-purpose flour
- ½ cup (45g) unsweetened cocoa powder
- 1 teaspoon baking powder
- ½ teaspoon salt
- Zest of 1 large orange
- 1 cup (150g) chocolate chips (optional)
Notes on Ingredient Quality
Choosing the right ingredients makes a big difference. Use fresh butter for a rich flavor. Granulated sugar adds sweetness. Brown sugar gives moisture and depth. Your sourdough discard should be active for the best texture. Always pick quality eggs; they enhance the overall taste. Pure vanilla extract is key for a lovely aroma. For flour, make sure it’s all-purpose, and check for freshness in cocoa powder. If you love chocolate, use good quality chocolate chips; they will add richness.
Suggested Substitutes
If you run out of unsalted butter, you can use coconut oil or margarine. Instead of granulated sugar, you can use coconut sugar for a different flavor. If you don’t have brown sugar, just add more granulated sugar; your brownies will still be yummy. For the eggs, you can use flaxseed meal mixed with water if you want a vegan option. If you are gluten-free, almond or oat flour works well in place of all-purpose flour.

Step-by-Step Instructions
Preparation Steps Overview
First, gather all your ingredients. You will need butter, sugars, sourdough discard, eggs, vanilla, flour, cocoa powder, baking powder, salt, orange zest, and optional chocolate chips. Preheat your oven to 350°F (175°C). Prepare a 9x13-inch baking pan by greasing it or lining it with parchment paper. This step helps with easy brownie removal later.
Detailed Baking Process
In a large bowl, melt the butter. Mix in granulated sugar and brown sugar. Whisk until the mixture is smooth. Add your sourdough discard. Then, crack in the eggs and pour in the vanilla extract. Stir until the batter is even.
In a separate bowl, sift together flour, cocoa powder, baking powder, and salt. Gradually fold this dry mix into the wet one. Be gentle; stop mixing as soon as you see no more flour. Now, fold in the orange zest and chocolate chips, if you want.
Pour the batter into the prepared pan. Use a spatula to spread it evenly. This step helps the brownies bake uniformly.
Testing for Doneness
Bake your brownies for 25-30 minutes. To check if they’re done, stick a toothpick into the center. It should come out with a few moist crumbs but not wet batter. Once baked, let the brownies cool in the pan for 15 minutes. Then, move them to a wire rack to cool completely. After cooling, cut them into squares and enjoy!
Tips & Tricks
How to Achieve the Best Texture
For a chewy brownie, use room temperature eggs. Cold eggs can make your batter dense. Mix your butter and sugars well. This step adds air, making brownies light. Avoid overmixing the batter after adding flour. This keeps the brownies tender. Pull them from the oven when a toothpick shows a few moist crumbs.
Flavor Enhancements and Additions
To boost flavor, add a pinch of sea salt. This brings out the chocolate taste. You can also mix in nuts, like walnuts or pecans. For a richer taste, try dark chocolate chips instead of semi-sweet ones. A splash of espresso powder can deepen the chocolate flavor, too. Lastly, don’t skip the orange zest; it brightens every bite!
Common Baking Mistakes to Avoid
One mistake is not measuring ingredients correctly. Always use a kitchen scale for accuracy. Another pitfall is baking at too high a temperature. Stick to 350°F (175°C) for best results. Avoid opening the oven door too soon. This can cause brownies to sink. Lastly, let them cool fully before cutting. This helps them hold their shape.

Variations
Alternative Flavor Combinations
You can change the flavor of these brownies in fun ways. Try adding nuts, like walnuts or pecans, for a crunchy bite. You can also mix in dried fruits, such as cherries or cranberries, to add a chewy texture. For a minty twist, use mint extract instead of vanilla. Another idea is to add a splash of espresso for a deeper chocolate flavor. These small changes can make your brownies unique and exciting.
Gluten-Free/Baking Adaptations
To make these brownies gluten-free, swap the all-purpose flour with a gluten-free blend. Look for a mix that includes a binding agent, like xanthan gum, to help hold the brownies together. You may need to adjust the baking time slightly. Keep an eye on them as they bake. Gluten-free brownies may need a bit longer to set.
Vegan Version Substitutions
You can make a vegan version of these brownies easily. Replace the eggs with flax eggs. To make one flax egg, mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water. Let it sit for a few minutes to thicken. Use a plant-based butter instead of regular butter. Also, make sure your chocolate chips are dairy-free. These swaps will help you create tasty vegan brownies without missing out on flavor.
Storage Info
Best Ways to Store Brownies
To keep your brownies fresh, store them in an airtight container. Place a piece of parchment paper between layers to prevent sticking. You can keep them at room temperature for easy access. If you live in a warm area, consider refrigerating them. This helps keep the texture nice and firm.
How Long Do They Last?
When stored properly, these brownies can last up to a week at room temperature. If you refrigerate them, they can stay fresh for about 10 days. However, they might lose some of their tenderness after a few days.
Freezing Instructions
For longer storage, you can freeze your brownies. First, let them cool completely. Then wrap each brownie in plastic wrap and place them in a freezer bag. They can last up to three months in the freezer. When you're ready to eat, simply thaw them at room temperature. Enjoy the rich flavors anytime!
FAQs
Can I use a different type of flour?
Yes, you can use other flours. Whole wheat flour works well. Almond flour can also be a good choice. Just note that it may change the texture. If you use gluten-free flour, check the package for best results.
What is the best way to cut brownies?
To cut brownies, first cool them completely. Then, use a sharp knife. Clean the knife between cuts for neat squares. You can also use a plastic knife for easier slicing.
Can I make these without the orange zest?
Absolutely! You can skip the orange zest if you want. The brownies will still taste great. However, the zest adds a fresh flavor that brightens the dish.
How can I tell if my brownies are undercooked?
To check if your brownies are undercooked, insert a toothpick in the center. If it comes out with wet batter, they need more time. If it has a few moist crumbs, they are done.
