If you’ve been nurturing a sourdough starter, you’ll love this recipe for transforming that discard into something truly special. These brownies boast a crackly top, a super fudgy interior, and a sophisticated chocolate flavor that will have everyone asking for seconds. Let’s get baking!
Ingredients:
- 8 tablespoons unsalted butter
- 12 oz. semi sweet chocolate chips
- 1/2 cup dutched cocoa powder (or regular cocoa powder)
- 2 teaspoons vanilla extract
- 2 large eggs
- 1 egg yolk
- 1 cup granulated sugar
- 1/2 cup dark brown sugar
- 1/2 cup sourdough starter discard
- 1 cup all-purpose flour
- 1 teaspoon salt
Getting Started: Melting the Chocolate and Butter
The foundation of any great brownie is a rich, chocolatey base. We’ll start by gently melting our butter and semi-sweet chocolate chips. This can be done in a few ways, but my favorite is the double boiler method. Find a heatproof bowl that fits snugly over a saucepan without touching the water. Fill the saucepan with about an inch of water and bring it to a gentle simmer over medium-low heat. Place your unsalted butter and 12 ounces of semi-sweet chocolate chips into the heatproof bowl. Stir occasionally as the butter melts and the chocolate begins to soften. Continue stirring until everything is smooth and glossy. Once melted, remove the bowl from the heat and let it cool slightly for a few minutes. This step is crucial; if the chocolate mixture is too hot, it can cook the eggs prematurely.
Incorporating the Wet Ingredients and the Sourdough Magic
Once our chocolate mixture has cooled down a bit, we’ll whisk in the flavor enhancers. Add 2 teaspoons of vanilla extract to the melted chocolate and butter. Next, it’s time to incorporate the eggs. Crack in your 2 large eggs and 1 additional egg yolk. The extra yolk is our secret weapon for achieving that incredibly fudgy texture that everyone loves in a brownie. Whisk these ingredients together thoroughly until everything is well combined and the mixture is smooth and emulsified. Now for the sourdough starter discard! Gently stir in your 1/2 cup of sourdough starter discard. Don’t worry if it looks a little lumpy; it will incorporate as you mix in the dry ingredients. The starter’s natural acidity will react with the leavening agents and contribute to that desirable crackly top and chewy texture.
Adding the Sugars and Dry Ingredients
With our wet ingredients well combined, it’s time to sweeten things up and introduce the dry components. Add 1 cup of granulated sugar and 1/2 cup of dark brown sugar to the chocolate mixture. The brown sugar adds moisture and a lovely caramel note that complements the chocolate beautifully. Whisk these sugars into the wet ingredients until fully incorporated. Now, let’s bring in the dry ingredients. In a separate bowl, whisk together 1 cup of all-purpose flour and 1 teaspoon of salt. The salt is essential for balancing the sweetness and enhancing the chocolate flavor. Gradually add the dry ingredients to the wet ingredients, mixing with a spatula or wooden spoon until just combined. Be careful not to overmix at this stage; overmixing can develop the gluten in the flour, leading to tougher brownies. We want a rich, fudgy texture, not a cakey one. A few streaks of flour are perfectly fine.
Baking the Perfect Sourdough Brownies
Preheat your oven to 350°F (175°C). Prepare an 8×8 inch baking pan by greasing it and lining it with parchment paper, leaving an overhang on the sides. This overhang will make it easy to lift the brownies out of the pan once they’re baked. Pour the brownie batter into the prepared pan and spread it evenly. You can even tap the pan gently on the counter a few times to help level the batter and release any air bubbles. Now, it’s time to bake! Place the pan in the preheated oven and bake for 25-30 minutes. The baking time is crucial for achieving the perfect fudgy texture. You’ll know they’re ready when the edges are set and a toothpick inserted into the center comes out with moist crumbs attached, not wet batter. If you prefer a more cake-like brownie, you can bake them a few minutes longer, but for ultimate fudginess, err on the side of slightly underbaked.
Cooling and Enjoying Your Masterpiece
This is arguably the hardest part: waiting for the brownies to cool! Once they come out of the oven, resist the urge to cut into them immediately. Let them cool in the pan on a wire rack for at least 30 minutes. This allows them to set up properly and makes them much easier to cut. For the absolute best texture and flavor, I highly recommend letting them cool completely, and even chilling them in the refrigerator for an hour or two before slicing. This chilling step further intensifies the fudgy texture and makes for cleaner cuts. Once cooled, use the parchment paper overhang to lift the entire brownie slab out of the pan. Slice into squares using a sharp knife. These sourdough brownies are incredible on their own, but they’re also fantastic served with a scoop of vanilla ice cream or a dollop of whipped cream. Enjoy the unique and delicious tang of your homemade sourdough brownies!
