Sourdough Discard Brownies

If you’re anything like us, you’re always looking for delicious ways to use up extra sourdough discard. These sourdough discard brownies have become a favorite in our house — rich, fudgy, chocolatey, and incredibly simple to make. The sourdough discard adds a subtle depth of flavor while helping create that soft, chewy texture that makes homemade brownies so hard to resist.

As always, we use organic flour and organic cane sugar in our kitchen. After making the switch away from enriched flour, we noticed a huge difference for our family, and we love being able to make homemade treats with simple ingredients we feel good about serving.

These brownies come together quickly in one bowl and bake beautifully in a 9x13 pan, making them perfect for family movie nights, potlucks, or just using up that sourdough discard sitting in the fridge.

Tips

• These are delicious warm with a scoop of vanilla ice cream.
• You can easily add chopped walnuts or pecans for extra texture.
• The flavor gets even better the next day as the sourdough notes deepen slightly.
