Ingredients
Complete List of Ingredients
To make these easy sourdough brownies, you'll need a few key ingredients. Here’s what to gather:
- 1 cup sourdough starter (can be fed or unfed)
- 1/2 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/2 cup granulated sugar
- 1/2 cup brown sugar, tightly packed
- 1/2 cup melted butter (or vegetable oil for a lighter option)
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1/2 teaspoon salt
- 1 cup chocolate chips (optional for extra indulgence)
Now, let's break down a few important ingredients:
Sourdough Starter Options You can use either fed or unfed sourdough starter. Fed starter gives more flavor and rise. Unfed starter works well, too. Both options work in this recipe.
Types of Sugars to Use I like using both granulated and brown sugar. Granulated sugar adds sweetness. Brown sugar makes the brownies chewier and richer. Using both gives the best taste and texture.
Cocoa Powder Selection Tips Choose high-quality unsweetened cocoa powder. It adds depth and richness to the brownies. Look for Dutch-processed cocoa for a smoother flavor. Regular unsweetened cocoa works great, too.

Step-by-Step Instructions
Prepping the Oven and Baking Pan
Start by preheating your oven to 350°F (175°C). This step is key for even baking. Next, grab an 8x8-inch baking pan. Grease it lightly, then line it with parchment paper. Leave some paper hanging over the edges. This makes it easy to lift the brownies out later. If you don’t have an 8x8 pan, you can use a 9x9 pan. Just keep an eye on the baking time, as it may change.
Mixing Wet Ingredients
In a large bowl, mix together the sourdough starter, melted butter, granulated sugar, and brown sugar. Use a whisk or a spatula to blend well. You want a smooth batter with no lumps. Next, add the eggs one at a time. Mix well after each egg. This helps the batter come together. Finally, stir in the vanilla extract for flavor.
Preparing Dry Ingredients
In a separate bowl, sift the cocoa powder, flour, and salt. Sifting helps to remove lumps and makes mixing easier. Gradually add the dry mix to the wet batter. Fold gently with a spatula. Be careful not to overmix; this can make the brownies tough. The batter should be thick and smooth.
Baking and Cooling
Pour the brownie batter into your prepared pan. Spread it out evenly with a spatula. Bake in the oven for 25-30 minutes. To check for doneness, insert a toothpick in the center. It should come out with moist crumbs, not wet batter. Once done, take the pan out and let it cool on a wire rack for about 15 minutes. Use the parchment paper overhang to lift the brownies out of the pan. Cut them into 16 squares. Enjoy them warm or let them cool completely!
Tips & Tricks
Perfecting the Brownie Texture
How does sourdough affect the final product? Sourdough adds a unique tang and moisture to brownies. This makes them rich and dense. The natural fermentation in sourdough also helps create a soft, chewy texture. You will love how it enhances the overall flavor!
Why is ingredient temperature important? Using room temperature eggs and butter leads to a smooth batter. This helps the ingredients mix better. Cold ingredients can lead to uneven baking. So, take your eggs and butter out in advance!
Enhancing Flavor
What optional ingredients can I add? You can add chocolate chips, nuts, or even swirls of peanut butter. Chocolate chips bring extra sweetness and richness. Nuts can add a nice crunch. Get creative and make them your own!
What flavor pairings should I consider? Think about adding espresso or coffee for depth. A hint of orange zest can brighten the flavor. These additions make your brownies even more special. Don't be afraid to experiment!
Pro Tips
- Use Room Temperature Ingredients: Make sure your eggs and butter are at room temperature before mixing. This helps to create a smoother batter and ensures even baking.
- Don’t Overmix: When combining the dry ingredients with the wet, mix just until incorporated. Overmixing can lead to dense brownies instead of the desired fudgy texture.
- Check for Doneness Early: Since ovens can vary, start checking your brownies a few minutes before the recommended baking time to prevent overbaking.
- Enhance Flavor with Coffee: For a deeper chocolate flavor, consider adding a teaspoon of instant coffee or espresso powder to the batter; it complements the cocoa wonderfully.
Variations
Dietary Modifications
You can easily change this recipe to fit your needs. For a gluten-free option, replace all-purpose flour with a gluten-free blend. This swap keeps the taste rich and delicious. Be sure to check the blend for baking properties.
If you need a dairy-free option, simply use vegetable oil instead of butter. You can also choose dairy-free chocolate chips. These changes keep your brownies moist and tasty, even without dairy.
Flavor Variations
Want to add some excitement? Try adding a bit of espresso or coffee to the batter. This addition deepens the chocolate flavor. Just one or two tablespoons can make a big difference.
For a fresh twist, add some citrus zest. Lemon or orange zest brightens the flavor. It adds a lovely contrast to the rich chocolate. Just a teaspoon will do the trick!
These variations not only make the brownies unique but also cater to different diets and tastes. You can have fun experimenting!
Storage Info
How to Store Brownies
To keep your brownies fresh, use an airtight container. This helps seal in moisture. You can store brownies at room temperature for up to four days. If you want to keep them longer, refrigerate them. The fridge can dry out brownies, so wrap them well in plastic wrap.
Freezing Brownies
Freezing brownies is easy and smart. First, cool them completely. Then, cut them into squares. Wrap each square in plastic wrap. Place the wrapped brownies in a freezer-safe bag. This way, they stay fresh for up to three months.
When you want to enjoy a brownie, take it out of the freezer. Let it thaw in the fridge for a few hours. For the best texture, warm it in the microwave for a few seconds. Enjoy the rich flavor just like the day you made them!
FAQs
Can I use a different type of flour?
Yes, you can swap all-purpose flour. Use whole wheat flour for a nuttier taste. You might also try almond flour for a gluten-free option. Just remember, different flours absorb moisture differently. You may need to adjust the liquid in your recipe if you switch.
What if I don’t have a sourdough starter?
If you lack a sourdough starter, you have options. You can use yogurt or buttermilk. These add tang and moisture, much like sourdough. Another choice is to simply make a quick batter with baking powder, baking soda, and a bit of vinegar. This will help your brownies rise without the sourdough.
How do I know when the brownies are done?
Check your brownies for doneness by using a toothpick. Insert it in the center. If it comes out with moist crumbs, your brownies are ready. If it’s wet with batter, they need more time. Look for slight cracks on top, too; that’s a good sign!
