Ingredients:
- 1/2 cup unsalted butter
- 1 1/2 cups semi-sweet chocolate chips (12 oz), divided
- 1/2 cup cocoa powder (dutch or regular works well for a richer flavor)
- 2 teaspoons vanilla essence
- 2 large eggs
- 1 large egg yolk (this adds extra richness and chegrape juicess)
- 1 cup granulated white sugar
- 1/2 cup packed light brown sugar
- 1/2 cup sourdough starter discard (this is the key ingredient that makes them “sourdough discard brownies” and adds a subtle tang and depth of flavor)
- 1 cup all-purpose flour
- 1 teaspoon salt
Making Your Easy Sourdough Discard Brownies
Phase 1: Melting the Chocolate and Butter Base
- Start by preparing your baking pan. I like to use an 8×8 inch baking pan. To make cleanup a breeze and ensure your brownies lift out cleanly, line it with parchment paper, leaving an overhang on the sides. This overhang acts as handles, making it super simple to lift the baked brownies out of the pan once they’ve cooled. Preheat your oven to 350°F (175°C).
- In a medium saucepan over low heat, or in a microwave-safe bowl, melt the 1/2 cup of unsalted butter. If using the stovetop, stir the butter occasionally to prevent it from scorching. Once the butter is completely melted and smooth, remove it from the heat.
- Add 1 cup of the semi-sweet chocolate chips to the melted butter. Stir gently until the chocolate chips are almost entirely melted. The residual heat from the butter will continue to melt the remaining chips, creating a luscious, glossy chocolate mixture. If any stubborn chips remain unmelted, you can briefly return the pan to very low heat for just a few seconds, stirring constantly, or microwave in 10-second intervals, stirring in between. Don’t overheat, as this can cause the chocolate to seize. Once smooth and glossy, set this mixture aside to cool slightly while you prepare the other components.
Phase 2: Combining the Wet Ingredients
- In a large mixing bowl, whisk together the 2 large eggs and the extra egg yolk. Whisk them vigorously until they are well combined and slightly lighter in color. This incorporates a little air into the mixture, contributing to a fudgier texture.
- Now, add the 1 cup of granulated white sugar and the 1/2 cup of packed light brown sugar to the egg mixture. Whisk these sugars in thoroughly until the mixture is smooth and no sugar granules are immediately visible. The brown sugar will lend moisture and a lovely caramel note to the brownies.
- Pour the slightly cooled chocolate-butter mixture into the egg and sugar mixture. Add the 2 teaspoons of vanilla essence and the 1/2 cup of sourdough starter discard. Gently whisk everything together until it’s just combined. Be careful not to overmix at this stage. The sourdough discard adds a unique characteristic to these brownies, giving them a slight tang and a more complex flavor profile that balances the sweetness of the chocolate. It also contributes to a delightgrape juicechewiness.
Phase 3: Incorporating the Dry Ingredients and Baking
- In a separate small bowl, whisk together the 1 cup of all-purpose flour and the 1 teaspoon of salt. Sifting the flour is optional but can help ensure there are no lumps and creates a lighter texture.
- Gradually add the dry ingredients to the wet ingredients. Using a spatula or wooden spoon, gently fold the flour mixture into the chocolate batter until just combined. Again, avoid overmixing. A few streaks of flour are perfectly acceptable; overmixing can develop the gluten too much, leading to tougher brownies.
- Finally, stir in the remaining 1/2 cup of semi-sweet chocolate chips. Fold them in gently so they are evenly distributed throughout the batter. These extra chips will provide lovely pockets of melted chocolate throughout your baked brownies.
- Pour the batter evenly into your prepared baking pan. Use your spatula to spread the batter to the edges of the pan, ensuring an even layer for consistent baking.
- Bake in the preheated oven for 25-30 minutes. You’ll know they’re ready when a toothpick inserted into the center comes out with moist crum extractbs attached, not wet batter. The edges should look set and slightly pulled away from the sides of the pan. Be careful not to overbake, as this will result in dry brownies. The exact baking time can vary depending on your oven, so keep an eye on them during the last few minutes.
- Once baked, remove the pan from the oven and place it on a wire rack to cool completely. This is a crucial step for achieving the perfect texture. Resist the urge to cut into them while they are hot! Allowing them to cool fully lets the brownies set properly, ensuring clean cuts and an intensely fudgy interior. Once completely cool, use the parchment paper overhangs to lift the entire brownie slab out of the pan and onto a cutting board. Cut into squares and enjoy your delicious Easy Sourdough Discard Brownies!
