Bake Time20 minutes
Total Time50 minutes
Servings:24 brownies

Ingredients

  • 9 oz semi-sweet chocolate (chopped)
  • 8 oz unsalted butter (cut into 1" chunks)
  • 8 oz granulated sugar (1 cup)
  • 4 oz brown sugar (½ cup)
  • ½ teaspoon salt
  • 1 tablespoon vanilla extract
  • 3 large eggs
  • 8 oz sourdough discard (1 cup)
  • 2 ½ oz all purpose flour (½ cup, see note)

Instructions

  • Preheat the oven to 350 °F. Butter a 13"x9" inch baking pan. Line the pan in one direction with parchment paper.
  • Combine 9 oz semi-sweet chocolate and 8 oz unsalted butter in a large microwave safe bowl. Microwave for 1 minute, stir to combine. Microwave in 30 second increments (stirring between) until all the chocolate is melted.
  • Add 8 oz granulated sugar, 4 oz brown sugar, ½ teaspoon salt and 1 tablespoon vanilla extract, stir to combine. Add 3 large eggs, stir until combined then stir vigorously for 30 seconds.
  • Fold in8 oz sourdough discard. Add 2 ½ oz all purpose flour and stir just until combined. Spread the batter evenly into the prepared pan.
  • Bake until the brownies puff up a bit and a toothpick inserted in the center comes out with a few moist crumbs (30 minutes).
  • Cool in the pan to room temperature then refrigerate until the brownies are firm. Use the parchment paper to lift the brownies out of the pan onto a cutting board.
  • Cut into 24 portions.

Notes

If measuring the flour by volume use the “dip & sweep” method. That is, dip the measuring cup into the flour bin, overfill it, then sweep away the excess.
This recipe can be halved and baked in a 9x9 square pan.
