Ingredients Method Notes

Ingredients
  

For the Brownies
  • ½ cup unsalted butter
  • 1 cup granulated sugar
  • ½ cup packed brown sugar
  • 1 cup sourdough starter (discard or active)
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour
  • ⅓ cup unsweetened cocoa powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup chocolate chips (optional but highly recommended) For added chocolatey flavor

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and grease a 9x9 inch baking pan.
  2. In a medium saucepan, melt the butter over low heat. Once melted, remove from heat and stir in both sugars until well combined.
  3. Mix in the sourdough starter and vanilla extract until smooth.
  4. In another bowl, sift together the flour, cocoa powder, baking soda, and salt.
  5. Slowly add the dry mixture into the wet mixture, stirring until just combined. Avoid over-mixing!
  6. Fold in chocolate chips if desired.
Baking
  1. Pour the brownie batter into the prepared pan and spread evenly.
  2. Bake for 20-25 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
Cooling and Serving
  1. Allow the brownies to cool in the pan for about 10 minutes before transferring to a wire rack.
  2. Cut into squares, serve warm, and enjoy!

Notes

For best results, check the batter consistency. It should be thick but pourable. Add milk or more sourdough starter if it’s too dry. Allow brownies to cool completely before cutting for cleaner cuts. Store in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week.
