When I first experimented with these brownies, I didn’t expect the difference using sourdough discard would make. The combination of chocolate and sourdough creates a depth of flavor that takes brownies to the next level. I’ve tried various methods, but ensuring the dough is not overmixed is key to achieving that perfect crackly top.

One invaluable tip I discovered is to let the brownies sit for a few minutes after baking before cutting into them. This allows the structure to set better, resulting in clean, gorgeous edges. I love serving these with a scoop of vanilla ice cream for extra indulgence!

Understanding Sourdough Discard

Sourdough discard is often seen as a kitchen burden, but it can be a treasure trove for baking. In this brownie recipe, the sourdough adds moisture and a unique tang that enhances the overall flavor profile. This acidity can also help balance the sweetness of the sugars, resulting in a more complex and satisfying dessert. When using sourdough discard, make sure it is active and bubbly for the best flavor contribution.

In addition to its flavor benefits, using sourdough discard helps reduce food waste, aligning with sustainable cooking practices. Instead of tossing out your discard, repurpose it into delicious treats like these brownies. By incorporating leftover sourdough into your baking, you not only elevate your desserts but also contribute to a more environmentally friendly kitchen.

Achieving the Perfect Texture

The crackly top of these brownies is part of what makes them so enticing. To achieve this iconic texture, ensure you mix the sugars and melted butter vigorously until the mixture is glossy and slightly thickened. This helps to incorporate air, which is crucial for that signature top. Be cautious not to overmix once you add the dry ingredients; overmixing can lead to denser brownies instead of the desired fudgy texture.

Additionally, the quality of chocolate chips plays a significant role in the final flavor and texture. I recommend using good-quality chocolate, as it will melt beautifully and enhance the richness of the brownies. If you're a fan of nuts, consider adding some chopped walnuts or pecans for added crunch, but mix them in gently to preserve the texture you've worked hard to create.

Ingredients

Gather all your ingredients before you start for a smooth baking experience:

Brownie Ingredients

1 cup (200g) granulated sugar
1/2 cup (100g) packed brown sugar
1/2 cup (115g) unsalted butter, melted
2 large eggs
1 cup (240g) sourdough discard
1 teaspoon vanilla extract
1/2 cup (65g) all-purpose flour
1/3 cup (40g) unsweetened cocoa powder
1/4 teaspoon baking soda
1/4 teaspoon salt
1 cup (175g) chocolate chips

Combine the ingredients well, ensuring the mixture is smooth and free of lumps.

Instructions

Follow these steps to achieve brownie perfection:

Preheat the Oven

Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.

Mix Wet Ingredients

In a large bowl, whisk together the granulated sugar, brown sugar, and melted butter until well combined. Add the eggs, sourdough discard, and vanilla extract, mixing until smooth.

Combine Dry Ingredients

In another bowl, sift together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Add Chocolate Chips

Fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.

Bake the Brownies

Pour the batter into the prepared baking pan and smooth the top. Bake in the preheated oven for 25 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.

Cool and Slice

Let the brownies cool in the pan for at least 10 minutes before slicing into squares. Enjoy!

Your brownies are now ready to be devoured! Serve them warm or at room temperature.

Pro Tips

You can customize these brownies by adding nuts or your favorite candies to the batter. For a more intense chocolate flavor, consider using dark chocolate chips instead of semisweet.

Storage Tips

To maintain the deliciousness of your brownies, store them in an airtight container at room temperature for up to five days. If you’d like to keep them longer, consider freezing them. Cut the brownies into squares, wrap each piece tightly in plastic wrap, and place them in a freezer-safe container. They can last up to three months in the freezer, allowing you to enjoy this delightful treat whenever the craving strikes.

When you're ready to enjoy a frozen brownie, simply thaw it at room temperature for about 30 minutes, or microwave it for 10-15 seconds for a warm, fresh-baked taste. This method ensures the brownies retain their soft texture and rich flavor, making them perfect for a quick indulgence.

Variations and Additions

While these brownies shine on their own, you can easily customize them for your taste. Try adding a swirl of peanut butter or caramel sauce to the batter before baking for an extra layer of flavor. You can also experiment with different types of chocolate chips, such as dark, milk, or white chocolate, depending on your preference. Each option will give a distinct taste and texture that can make your brownies uniquely yours.

For a more decadent treat, consider topping the brownies with a layer of ganache made from equal parts of heavy cream and chocolate. Simply heat the cream until it just begins to simmer, pour it over the chopped chocolate, and stir until smooth. This addition not only enhances the chocolate flavor but also creates a luxurious finish that elevates the overall dessert experience.
