Ingredients

  • 8 tablespoons (113 g) unsalted butter
  • 12 oz. (340 g) semi sweet chocolate chips
  • ½ cup (40 g) dutched cocoa powder or regular cocoa powder
  • 2 teaspoons (10 g) vanilla extract
  • 2 large eggs
  • 1 egg yolk
  • 1 cup (200 g) granulated sugar
  • ½ cup (110 g) dark brown sugar
  • ½ cup (125 g) sourdough starter discard
  • 1 cup (120 g) all-purpose flour
  • 1 teaspoon (5 g) salt

Instructions

  • Preheat oven to 350°F (176°C) and line a 9" x 9" baking dish with parchment paper.
  • Melt the butter in a small saucepan over low heat. Add the chocolate chips, vanilla extract and dutched cocoa powder. Stir the ingredients until the chocolate chips have melted and the mixture is smooth. Remove the saucepan from the burner and set it aside to cool down.

  • In a large mixing bowl, beat the eggs, brown sugar and granulated sugar with an electric mixer for 7-10 minutes. Add the sourdough discard and chocolate mixture to the bowl beat on low until combined. Add the flour and salt and stir with a spatula until just combined. (The batter will be very thick.)

Notes

  • To Store: Allow the brownies to cool completely after they come out of the oven. Store them in an airtight container or cover with plastic wrap. Keep them at room temperature for up to 7 days.
  • To Freeze: After brownies have cooled, wrap individual baked brownies in plastic wrap and place in a freezer-safe container or bag. Keep in the freezer for up to three months.
  • To Reheat: Allow brownies to thaw, if frozen. Place in the microwave for 10-15 seconds on high.
