Ingredients
  

For the chocolate blend:

  • 2 tsp vanilla extract
  • 12 oz semi-sweet chocolate chips
  • 1/2 cup unsalted butter
  • 1/2 cup cocoa powder

For the wet ingredients:

  • 1/2 cup sourdough starter discard
  • 1/2 cup brown sugar
  • 1 cup white sugar
  • 1 egg yolk
  • 2 large eggs

For the dry ingredients:

  • 1 cup plain flour
  • 1 tsp salt

Instructions
 

  • Preheat oven to 350°F (176°C) and line a 9×9-inch baking dish with parchment paper.
  • Melt butter over low heat, then add chocolate chips, cocoa powder, and vanilla. Stir until smooth. Let cool slightly.
  • In a large bowl, beat eggs, egg yolk, brown sugar, and white sugar for 7–10 minutes until light and creamy.
  • Add sourdough discard and chocolate mixture, mixing gently until combined.
  • Fold in flour and salt until just incorporated. The batter will be thick.
  • Pour into the pan and smooth the top.
  • Bake for 35–40 minutes until a toothpick shows moist crumbs.
  • Cool completely before slicing your Sourdough Discard Brownies.

Notes

  • Add nuts or chocolate chunks for texture.
  • Serve warm with ice cream for an indulgent dessert.
  • Sprinkle flaky salt on top for contrast.
