Ingredients You’ll Need

8 tablespoons unsalted butter: This adds richness and moisture for that wonderful fudgy texture.
12 oz semi-sweet chocolate chips: Use good quality chocolate chips for the best flavor; if you prefer darker chocolate, feel free to swap in bittersweet chocolate.
¼ cup unsweetened cocoa powder: This intensifies the chocolatey flavor. Look for Dutch-processed cocoa for a smoother taste.
2 teaspoons vanilla extract: Adds a warm, inviting flavor that complements the chocolate.
2 eggs + 1 egg yolk: These provide structure and moisture, ensuring your brownies are rich and fudgy.
1 cup granulated sugar: Sweetness is crucial, and granulated sugar helps achieve that lovely crinkle top.
½ cup dark brown sugar: Brown sugar contributes moisture and a slight molasses flavor, enhancing the overall taste.
½ cup sourdough starter discard: The star of the show! It adds flavor and helps create a tender crumb. If you don’t have a starter, you can omit it, but the brownies will be less tangy.
1 cup all-purpose flour: This gives structure to the brownies without making them too cakey.
1 teaspoon salt: Elevates all the flavors, balancing the sweetness with a touch of savoriness.

How to Make Sourdough Discard Brownies

Preheat and Prepare: Start by preheating your oven to 350°F (175°C). Line a 9×9 inch baking dish with parchment paper to ensure easy removal later.
Melt Ingredients: In a small saucepan over low heat, melt the 8 tablespoons of unsalted butter. Once melted, whisk in the ¼ cup of unsweetened cocoa powder, 2 teaspoons of vanilla extract, and the 12 oz of semi-sweet chocolate chips until the mixture is smooth and glossy. Remove from heat and let cool for a few minutes.
Beat Eggs and Sugars: In a large mixing bowl, use an electric mixer to beat together the 2 eggs, 2 egg yolk, ½ cup dark brown sugar, and 1 cup granulated sugar for about 8-10 minutes. You’re aiming for the mixture to be light and fluffy; this process helps form the shiny, crinkly top that brownies are famous for.
Combine Mixtures: Slowly add the cooled chocolate mixture and the ½ cup of sourdough starter discard to the egg mixture. Beat on low speed until just combined, being careful not to overmix.
Add Dry Ingredients: Gently stir in the 1 cup of all-purpose flour and 1 teaspoon of salt until no streaks of flour remain. Don’t overmix, as this can lead to tough brownies.
Bake: Pour the brownie batter into your prepared baking pan and use a spatula to spread it evenly. Bake for about 35-40 minutes, or until a toothpick inserted in the center comes out with moist crumbs (meaning they’re perfectly baked).
Cool and Serve: Allow the brownies to cool completely in the pan before removing them by lifting the parchment paper. Cut them into squares and enjoy! For extra indulgence, serve with a scoop of vanilla ice cream or your favorite toppings.

Storing & Reheating

Store these delectable brownies at room temperature in an airtight container for up to 3 days. If you want to keep them longer, transfer to the refrigerator where they’ll stay good for about a week. For even longer storage, freeze individual brownie squares wrapped tightly in plastic wrap or placed in a freezer bag for up to 3 months. To reheat, simply pop them in the microwave for about 10-15 seconds until warm. They might lose some texture over time, but a quick warm-up brings back their fudginess!

Chef’s Helpful Tips

Don’t Overbeat the Batter: While it’s important to mix for the crinkle top, overmixing can lead to dense brownies. Stop mixing as soon as you see no flour streaks.
Egg Temperature Matters: Using room temperature eggs helps ingredients blend seamlessly, creating a better texture.
Use Quality Chocolate: The chocolate flavor shines through, so it’s worth investing in good chocolate chips.
Keep an Eye on Baking Time: Depending on your oven, keep checking for doneness starting at 35 minutes to avoid overbaking.
Experiment with Mix-ins: Feel free to add nuts, sea salt, or even a swirl of peanut butter for extra flavor!

These brownies are a delightful mixture of flavors and textures that brings joy with every bite. Not only are they an excellent way to use up sourdough starter, but they also shine as a treat in their own right.

Recipe FAQs

Can I use sourdough starter instead of sourdough discard?

Absolutely! You can use a regular sourdough starter. Just keep in mind that it should be at room temperature to ensure your brownies come out perfectly.

How can I make these brownies gluten-free?

To make gluten-free brownies, substitute the all-purpose flour with a 1:1 gluten-free flour blend. Be sure to check the blend contains xanthan gum, or add 1/4 teaspoon per cup to help with texture.

Can I add nuts or other mix-ins to the brownies?

Definitely! Adding chopped nuts such as walnuts or pecans enhances flavor and adds great texture. You can also combine in chocolate chunks, caramel swirls, or even dried fruits!

What can I do if the brownies turn out too cakey?

This can happen if they are overbaked or if too much flour was added. Make sure to bake them just until a toothpick comes out with moist crumbs. If they do get cakey, serve them warmed up with ice cream for a delicious treat!
