When I first decided to experiment with sourdough discard in brownies, I was unsure how it would turn out. It turned out to be a fantastic decision! The combination of sourdough and chocolate creates a unique flavor that is both comforting and intriguing. I found that letting the batter rest before baking really improves the texture, giving the brownies that perfect crispy top while keeping the insides fudgy.

One of my favorite tips is to sprinkle a tiny bit of sea salt on top before baking; it truly elevates the flavors. I also enjoy adding a handful of nuts or chocolate chips for extra texture. Every time I bake these brownies, they disappear in no time, and I love sharing them with friends and family!

The Role of Sourdough Discard

Using sourdough discard not only minimizes waste but also enriches the flavor profile of these brownies. The natural fermentation in sourdough gives the brownies a subtle tanginess that balances beautifully with the sweetness of chocolate. This unique aspect elevates them above ordinary brownies, making them truly special.

Another benefit of incorporating sourdough is the moisture it brings to the brownies. The discard helps to keep the texture fudgy and chewy, preventing the brownies from becoming too dry during baking. This is particularly important in creating that satisfying contrast between the crispy top and the soft, rich interior.

Tips for Perfect Texture

To achieve that ideal crispy exterior, ensure your oven is fully preheated to 350°F (175°C) before baking. This helps create that golden, slightly crunchy crust. After pouring the batter into the greased pan, spreading it evenly with a spatula will allow for even baking and consistent texture, so don’t skimp on this step.

When testing for doneness, insert a toothpick into the center; it should come out with a few moist crumbs. This is crucial because overbaking will lead to a dry texture, which can compromise the overall enjoyment of your brownies. Remember, they will continue to firm up slightly as they cool.

Ingredients

Gather the following ingredients to get started:

Ingredients

1 cup sourdough discard
1 cup granulated sugar
1/2 cup unsalted butter, melted
2 large eggs
1 teaspoon vanilla extract
1/2 cup all-purpose flour
1/2 cup cocoa powder
1/4 teaspoon baking powder
1/4 teaspoon salt
1/2 cup chocolate chips (optional)
1/4 cup chopped nuts (optional)

Make sure all ingredients are at room temperature for better mixing.

Instructions

Follow these simple steps to make your brownies:

Prepare the batter

In a large mixing bowl, combine the sourdough discard, sugar, and melted butter. Whisk until smooth. Add the eggs and vanilla, and mix well.

Combine dry ingredients

In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually mix these dry ingredients into the wet mixture until just combined.

Add chocolate chips and nuts

Fold in the chocolate chips and nuts if using, ensuring even distribution throughout the batter.

Bake the brownies

Pour the batter into a greased 8x8 inch baking pan. Use a spatula to spread it evenly. Bake in a preheated oven at 350°F (175°C) for 25 minutes or until a toothpick inserted comes out with a few moist crumbs.

Cool and serve

Let the brownies cool in the pan for at least 10 minutes before cutting into squares. Enjoy your delicious sourdough brownies!

Serve warm with a scoop of ice cream for an extra indulgent treat!

Pro Tips

For an even richer flavor, try using dark chocolate cocoa powder or adding a pinch of espresso powder to the batter.

Ingredient Substitutions

If you're out of unsalted butter, you can substitute with an equal amount of coconut oil or vegetable oil, which will still provide the necessary fat for a rich flavor. For a dairy-free option, look for plant-based butter. Just be aware that this may alter the final flavor slightly.

For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free flour blend. This will maintain the texture while making the brownies accessible to those with gluten sensitivities. Ensure the blend you choose contains xanthan gum for proper binding.

Making Ahead and Storage

These brownies can be made ahead of time and stored in an airtight container at room temperature for up to three days. For longer storage, consider freezing them. Wrap the cooled brownies tightly in plastic wrap, then place them in a freezer bag. They will keep well for up to three months; simply thaw at room temperature before serving.

If you want a fresh-baked experience, you can reheat individual brownie squares in the microwave for about 10-15 seconds. This will warm them through, slightly melting the chocolate chips for an extra gooey treat.
