Ingredients
  

Brownie Base
  • 1 cup unsalted butter (2 sticks) Melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 cup unsweetened cocoa powder
  • 1 cup sourdough starter (discard or fresh)
  • 1 teaspoon vanilla extract
  • 1 cup all-purpose flour Can be substituted with gluten-free blend
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup chocolate chips Optional for extra indulgence

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C).
  2. Grease a 9x13-inch baking pan or line it with parchment paper.
  3. In a medium saucepan, melt the unsalted butter over low heat. Remove from heat and let cool slightly.
Mixing
  1. In a large mixing bowl, combine the granulated sugar and slightly cooled melted butter. Whisk in the eggs, one at a time, until smooth.
  2. Stir in the sourdough starter and vanilla extract until fully combined.
  3. In another bowl, sift together cocoa powder, all-purpose flour, baking powder, and salt.
  4. Gradually fold the dry mixture into the wet mixture until combined but do not overmix.
  5. Fold in the chocolate chips if using.
Baking
  1. Transfer the brownie batter to the prepared baking pan and spread evenly.
  2. Bake for 25-30 minutes, or until a toothpick comes out with a few moist crumbs.
  3. Allow brownies to cool in the pan for about 10 minutes before transferring to a wire rack. Cut into squares.

Notes

Store leftovers in an airtight container for up to a week or freeze for up to three months. Reheat in the microwave for 10-15 seconds or in the oven at a low temperature.
