How to Make Sourdough Discard Brownies
-
Preheat the Oven:
Preheat your oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper and lightly grease it. -
Mix Wet Ingredients:
In a large mixing bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth. Add eggs and vanilla extract, whisking until the mixture becomes glossy and slightly thickened. -
Add the Sourdough Discard:
Stir in the sourdough discard until well combined. The batter might look slightly lumpy—this is normal! -
Combine Dry Ingredients:
In a separate bowl, sift together the flour, cocoa powder, baking powder, and salt. -
Mix Everything Together:
Gently fold the dry ingredients into the wet mixture until just combined. Avoid overmixing to keep your brownies tender. -
Add Toppings:
Fold in chocolate chips or nuts if using. Pour the batter into the prepared pan, spreading it evenly. -
Bake:
Bake for 30–35 minutes or until a toothpick inserted in the center comes out with a few moist crumbs (not completely clean). -
Cool and Serve:
Allow the brownies to cool completely in the pan before cutting into squares. Enjoy!
Notes
-
If you prefer cakier brownies, increase baking powder to 1 teaspoon.
-
For extra fudgy texture, underbake slightly and chill for 30 minutes before cutting.
-
Your sourdough discard can be from white, whole wheat, or rye starter—each gives a unique flavor.
-
Store brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
FAQs

A: Absolutely! Substitute butter with coconut oil or vegan butter.
Q: Why use sourdough discard in brownies?
A: The discard adds a mild tang and helps reduce food waste while enhancing the fudginess.
