These easy to make sourdough brownies are a great way to use sourdough discard. With one bowl, one pan, and about 30 minutes, you have rich, fudgy brownies.


Units Scale
  • 1/2 cup sourdough starter
  • 4 eggs
  • 4 ounces melted chocolate
  • 1/2 cup granulated sugar
  • 1/4 cup butter or coconut oil (room temperature or melted)
  • 1/2 teaspoon vanilla
  • 1/8 teaspoon sea salt
  • 1/2 teaspoon baking soda
  • crispy nuts (optional)


Preheat your oven to 350 degrees Fahrenheit and grease your baking dish.

In a blender, food processor, or medium sized bowl, add sourdough starter and the rest of the ingredients (except nuts).

Blend (or whisk) chocolate mixture until smooth.

Pour the batter into your prepared pan. Sprinkle with nuts, if desired.

Place in oven and bake for 25 to 30 minutes,until toothpick inserted in the center tests done. The edges should be set but the center should still look a little soft. Don’t bake too long or the brownie will get tough and dry.

Let rest for 10 to 15 minutes before serving. Enjoy with a glass of cold milk, or ice cream or whipped cream if you want to get fancy.

These brownies freeze well and keep in a covered container in the fridge for one week.


Use granulated sugar, sucanat, rapadura, honey or maple syrup. Increase up to 1 cup for a sweeter brownie.

Use chocolate chips (1/2 cup), semiweet baking chocolate or a combination of 1/4 cup cocoa powder + 2 1/2 tablespoons butter or coconut oil +1/4 cup sugar

This is a great way to use up sourdough discard, because your starter doesn’t need to be active for this recipe. These sourdough brownies work great with a wheat flour or rye flour starter.
