Ingredients

  • 4 ounces unsalted butter
  • 12 ounces semisweet chocolate chopped
  • 3/4 cup sugar
  • 3/4 cup powdered sugar
  • 1/2 cup sourdough discard
  • 2 eggs
  • 1 egg yolk
  • 1 teaspoon vanilla
  • 1 teaspoon coffee extract or additional vanilla
  • 1 cup all purpose flour
  • 1/2 cup cocoa powder
  • 1 1/4 teaspoon salt
  • 3/4 cup mini chocolate chips
  • flaky sea salt, for topping (optional)

Instructions

  • Butter an 8x8 inch or 9x9 inch baking dish. Preheat oven to 350° F.
  • Place butter and chopped chocolate in a metal bowl. Set bowl over a pot with an inch or two of water and bring it to a low simmer. Melt chocolate mixture slowly, stirring often. Once butter and chocolate are fully melted, remove from heat.
  • Whisk in sugars, whisking vigorously until well combined and shiny, about 3 minutes. Whisk in sourdough discard.
  • Add eggs, egg yolk, and vanilla and coffee extracts; whisk well to combine.
  • In a medium bowl, whisk together flour, cocoa powder, and salt. Add flour mixture to chocolate mixture and fold together gently with a spatula.
  • Fold in about 1/2 cup of the chocolate chips. Pour batter into prepared pan and sprinkle with remaining chocolate chips.
  • Bake until toothpick inserted in center comes out clean, about 30-40 minutes (time will vary based on material and size of baking pan). Top with flaky sea salt, if desired.
  • Allow to cool completely before slicing and eating.
