Ingredients You’ll Need
- 1 cup sourdough discard: This is the star of the show! It adds a unique tangy flavor and helps keep your brownies moist. If you don’t have enough discard, you can use a little less and add a splash of water or milk.
- 1 cup granulated sugar: This sweetness is necessary to balance the rich cocoa and ensure your brownies are delightfully sweet.
- ½ cup brown sugar: For an extra layer of moisture and a hint of caramel flavor, brown sugar rounds out the sweetness beautifully.
- ½ cup unsweetened cocoa powder: This provides the rich chocolate flavor that makes brownies so appealing; opt for high-quality cocoa for the best results.
- ½ cup melted butter: Using real butter enhances the richness and creamy texture of the brownies.
- 2 large eggs: Eggs bind everything together and contribute to that luscious texture.
- 1 teaspoon vanilla extract: A dash of vanilla adds warmth to the chocolate flavor.
- ½ teaspoon baking soda: Gives the brownies the lift they need to rise a bit while baking.
- ½ teaspoon salt: This enhances all the flavors, making them pop.
How to Make Sourdough Discard Chocolate Brownies
- Preheat your oven: Begin by preheating your oven to 350°F (175°C), ensuring it’s ready to bake your brownies to perfection.
- Prepare the pan: Grease an 8×8-inch baking pan with butter or line it with parchment paper for easy removal later.
- Mix the dry ingredients: In a large mixing bowl, whisk together 1 cup of granulated sugar, ½ cup of brown sugar, ½ cup of unsweetened cocoa powder, ½ teaspoon of baking soda, and ½ teaspoon of salt until well combined.
- Combine the wet ingredients: In another bowl, melt ½ cup of butter. Let it cool slightly, then stir in 1 cup of sourdough discard, 2 large eggs, and 1 teaspoon of vanilla extract until smooth.
- Blend dry and wet: Pour the wet ingredients into the bowl with the dry ingredients. Mix gently until just combined; be careful not to overmix, which can lead to dense brownies.
- Pour into the pan: Transfer the brownie batter to your prepared baking pan, spreading it evenly with a spatula.
- Bake: Place the pan in the preheated oven and bake for about 20-25 minutes, or until the edges look firm and a toothpick inserted in the center comes out with a few moist crumbs.
- Cool and enjoy: Allow your brownies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Slice and serve!
Storing & Reheating
To keep your brownies fresh, store them in an airtight container at room temperature for up to 3 days. If you want them to last longer, refrigerate them for up to a week. You can also freeze them in a freezer-safe container for up to 3 months. When you’re ready to enjoy a brownie, simply reheat it in the microwave for about 10-15 seconds, or warm them in the oven at 350°F (175°C) for a few minutes. Just note, the texture might change slightly after freezing, but a quick visit to the oven will refresh that fudgy goodness.
Chef’s Helpful Tips
- Be sure to mix the batter just until combined; overmixing can lead to tougher brownies.
- For a fudgier texture, try using melted chocolate in place of some or all of the cocoa powder.
- Using room temperature eggs helps them incorporate better into the batter.
- Consider adding chocolate chips or nuts to the batter for extra texture and flavor!
- Store your sourdough discard in the fridge, covered tightly, and use it within a week for optimal freshness.
