Sourdough brownies are decadent and indulgent chocolate treats created using a sourdough starter. What sets this recipe apart is that the starter serves as the sole source of flour, resulting in a unique twist - a fully fermented sourdough brownie. Sourdough brownies can be a fun and delicious twist on traditional brownies, especially for those who enjoy the unique flavor profile of sourdough. They can be enjoyed as a dessert or a sweet treat for any occasion.
These brownies achieve a remarkable combination of fudgy, gooey texture and a lighter crumb, thanks to the starter's influence. You will be surprised how the natural yeast can enhance the crumb structure, imparting a rich flavor to the brownies while keeping them delightfully light.
Why you will love this recipe?
- Unique flavor: The incorporation of sourdough starter introduces a tangy and distinct flavor profile to the brownies, setting them apart from traditional brownie recipes.
- Fermented goodness: By using the unfed sourdough starter as the only form of flour, these sourdough brownies are a unique twist on the classic treat. This fermentation not only makes them healthier but also adds depth and complexity to the flavor. It is also a great way of using up sourdough starter discard.
- Rich and fudgy texture: These easy sourdough brownies strike a delightful balance between fudgy and gooey. They offer a dense and moist texture that is highly satisfying, providing a rich and indulgent eating experience.
- Lighter crumb: Despite their fudgy texture, these brownies have a lighter crumb. The addition of sourdough starter contributes to the overall structure, resulting in a more tender and airy consistency.
- Natural yeast influence: The presence of natural yeast from the sourdough starter plays a role in making the texture of the sourdough brownie lighter while infusing them with a distinct flavor.
Sourdough starter: Use unfed or discard sourdough starter. 100% hydration sourdough starter discard made using bread flour, atta flour, rye flour, etc. can be used.
Chocolate: I use dark chocolate to make these sourdough brownies.
Butter: Use unsalted butter for this easy sourdough brownie recipe.
Eggs: I use two large eggs for this recipe.
Sugar: I use raw sugar to make these brownies. White sugar or dark brown sugar can also be used.
Step 1: Boil water in a saucepan to make a double boiler. In another medium bowl, place chocolate and butter, and keep it over the saucepan. Keep stirring using a silicon or rubber spatula on medium-low heat. Let the chocolate and butter melt completely (images 1 and 2).
Step 2: Take the bowl away from heat and let it stand for 2 minutes. Add granulated sugar and vanilla extract. Mix well until the sugar melts (image 3).
Step 3: Add salt, eggs, and baking soda next (image 4).
Step 4: Mix well. Add the sourdough starter to the chocolate and egg mixture (images 5 and 6).
Step 5: Incorporate the starter into the chocolate mixture. Pour into the prepared pan (images 7 and 8).
Step 6: Bake in the preheated oven for 25-28 minutes (step 9). Do a toothpick test to check if the fudgy brownies are done. Let it cool in the pan for 10 minutes before transferring it to the wire rack.
Use an unfed starter and not an active starter for this recipe. An active sourdough starter can be difficult to incorporate and may not give the correct batter consistency. Fold in the starter gently. Do not overmix the batter after adding the starter. This fudgy sourdough brownie recipe is the perfect way to use extra sourdough discard.
Bring the eggs to room temperature before using them.
Mix the batter very well after adding the eggs. Once the starter is added, just mix it gently to incorporate the starter.
Do not open the oven during the first 20 minutes of baking, else the brownie will sink.
Allow the brownies to cool completely before cutting. This will help them set properly and prevent them from crumbling. For clean and neat slices, use a sharp knife and wipe it clean between cuts.
Sourdough brownies often taste even better the next day. The flavors meld and develop further, so consider baking them in advance if possible. I love baking chocolate treats with sourdough. Check out this recipe to make delicious chocolate sourdough bread.
Variations of sourdough brownies
Here are a few variations you can try with these sourdough discard brownies. Remember to adjust the baking times accordingly when incorporating additional ingredients or variations into this sourdough brownie recipe.
Mint chocolate: Add a refreshing twist by incorporating mint extract or crushed mint candies into the brownie batter. You can also sprinkle some semi-sweet chocolate chips on top before baking.
Raspberry swirl: Create a tangy and fruity contrast by swirling raspberry jam into the brownie batter. Use a toothpick or a skewer to create swirl patterns. You can also top the sliced sourdough brownie with some fresh raspberries just before serving.
Espresso infusion: For coffee lovers, add one tablespoon of instant coffee powder to the batter to enhance the flavor. It will give these delicious brownies a rich and robust taste.
Sea salt and caramel: Sprinkle a pinch of sea salt flakes on top of the brownie batter before baking. Drizzle caramel sauce over the baked sourdough brownies for a sweet and salty combination.
Peanut butter: Swirl creamy peanut butter into the brownie batter for a decadent treat. You can also sprinkle chopped peanuts on top of the sourdough brownie batter for extra crunch.
Orange zest and chocolate: Add freshly grated orange zest to the batter to infuse it with a citrusy aroma. The combination of orange and chocolate is a classic pairing.
Storing sourdough brownies
Here is how to properly store sourdough brownies and maintain their freshness and texture:
- Allow it to cool completely: Before storing the sourdough brownies, ensure they have completely cooled down to room temperature. This helps prevent condensation and moisture buildup inside the storage container.
- Use an airtight container: Place the cooled brownies in an air-tight container to protect them from air exposure. This helps retain their moisture and prevents them from becoming dry.
- Layering: If you need to stack multiple layers of brownies, place a sheet of parchment paper or baking paper between each layer. This prevents the brownies from sticking together or causing damage when you separate them.
- Room temperature storage: Sourdough brownies can be stored at room temperature for 2 to 3 days. Ensure the storage area is cool, dry, and away from direct sunlight or heat sources.
- Refrigeration: If you live in a warm or humid climate or if you want to extend the shelf life, you can store the sourdough brownie in the refrigerator. Place the airtight container in the refrigerator and store the brownies for 5 to 7 days.
- Freezing: Sourdough brownies can be frozen for longer-term storage. Wrap the individual brownies or the entire batch tightly in plastic wrap, followed by aluminum foil, or place them in a freezer-safe container. A good brownie can be stored in the freezer for up to 3 months. Thaw the brownies in the refrigerator or at room temperature before serving.

My family loved the flavor of these sourdough brownies! I have been making more and more sourdough discard recipes and this by far is the best tasting recipe yet!!
I am not a baker and I don't make sour dough, but my sister is and she is always saying how she has starter left if I want to try making bread. I don't! But when I saw this recipe I knew exactly where to go to get a bit of starter.
The brownies were perfect. Just the right balance of chew and goo as we call it 😉
