Ingredients for Sourdough Discard Brownies
To make these rich and decadent brownies, you’ll need the following ingredients:
- ½ cup unsalted butter (melted)
- 1 cup granulated sugar
- 1 cup sourdough discard (from your starter)
- 2 large eggs
- 1 tsp vanilla extract
- ½ cup all-purpose flour
- ¼ cup unsweetened cocoa powder
- 1 tsp baking powder
- ½ tsp salt
- ½ cup chocolate chips (optional, for added richness)
- ¼ cup chopped nuts (optional, for extra crunch)
Step-by-Step Instructions for Making Sourdough Discard Brownies
Step 1: Preheat the Oven and Prepare the Baking Pan
Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal of the brownies once they are baked.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine the melted butter, sugar, and sourdough discard. Mix them together until well combined. You’ll notice that the discard adds a slightly tangy aroma to the mixture — that’s what makes these brownies unique! Next, add the eggs and vanilla extract, and whisk until smooth.
Step 3: Add the Dry Ingredients
In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Slowly add the dry ingredients to the wet mixture, mixing until just combined. Be careful not to overmix, as this can lead to dense brownies. If you’re using chocolate chips or nuts, fold them in at this stage for added texture and flavor.
Step 4: Pour and Bake
Pour the brownie batter into the prepared pan and spread it out evenly. Tap the pan gently on the counter to release any air bubbles and ensure an even distribution of the batter. Bake in the preheated oven for 25–30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). The top should be set and slightly cracked, and the edges should pull away from the pan.
Step 5: Cool and Serve
Allow the brownies to cool completely in the pan before slicing into squares. This cooling step helps set the brownies and gives them the perfect texture. Once cooled, cut them into squares, serve, and enjoy the rich, fudgy goodness with a slight tang from the sourdough discard.

Tips for Perfect Sourdough Discard Brownies
- Use fresh discard: The sourdough discard should be at least a few days old, as this will ensure the tangy flavor enhances the brownies.
- Don’t overmix: For the best texture, mix the wet and dry ingredients just until combined. Overmixing can cause the brownies to be dense.
- Try different add-ins: Add-ins like chocolate chips, chopped nuts, or even a sprinkle of sea salt on top can elevate the flavor of your brownies.
- Adjust the sweetness: If you prefer your brownies less sweet, feel free to reduce the sugar by a tablespoon or two.
- Let them cool: While it may be tempting to dive into the warm brownies right away, allowing them to cool will help them set better and provide a more satisfying bite.
