  • Total Time: 50 minutes
  • Yield: 16 servings

Ingredients

  • ½ cup (113 g) salted butter, browned
  • ½ cup (110 g) brown sugar
  • ¼ cup (55 g) granulated sugar
  • 1 egg (room temperature)
  • ½ cup (145 g) sourdough discard
  • 1 tbsp (15 g) heavy cream, room temperature
  • 1 tsp (4 g) vanilla extract
  • 1 cup + 6 tbsp (170 g) all-purpose flour
  • ½ tsp (3 g) baking soda
  • ½ tsp (2 g) baking powder
  • Pinch of salt
  • ¾ cup (150 g) chocolate chips
  • 1 cup (226 g) salted butter
  • 70 g cocoa powder (½ cup + 2 tbsp)
  • 6 oz dark chocolate chips
  • 2 tbsp (21 g) olive oil
  • 2 eggs + 1 egg yolk (room temperature)
  • ¾ cup (170 g) brown sugar
  • ¾ cup (150 g) granulated sugar
  • ½ cup (145 g) sourdough discard, room temperature
  • 2 tsp (8 g) vanilla extract
  • ½ cup + 1 tbsp (70 g) all-purpose flour
  • ½ tsp (3 g) salt
  • ¾ cup (150 g) chocolate chips or chocolate chunks
  • ½ cup melted chocolate

Instructions

  1. Preheat oven to 350°F (175°C). Grease and line a 9×9-inch pan with parchment paper.
  2. Brown the butter for the cookie layer, then let it cool a bit.
  3. In a bowl, mix the browned butter, brown sugar, and granulated sugar for the cookie layer.
  4. Add the egg, sourdough discard, heavy cream, and vanilla. Stir until smooth.
  5. Add flour, baking soda, baking powder, salt, and chocolate chips. Mix gently and set aside.
  6. Melt the butter with the cocoa powder and dark chocolate chips for the brownie layer, stirring until smooth. Let cool slightly.
  7. Stir in the olive oil, eggs, egg yolk, brown sugar, granulated sugar, sourdough discard, and vanilla.
  8. Fold in the flour, salt, and chocolate chips.
  9. Spread the brownie batter evenly in the prepared pan. Dollop the cookie dough on top by spoonfuls and spread gently for a marbled look.
  10. Bake for 30–35 minutes until set on top but still fudgy inside.
  11. Let cool in the pan, drizzle with melted chocolate, cut into squares, and serve.

Notes

Brown the butter slowly to avoid burning and let melted chocolate cool before adding eggs to avoid cooking them. Check doneness at 30 minutes with a toothpick.
