Servings: 12 servings

Ingredients

  • 1/2 cup unsweetened cocoa powder
  • 2 tablespoons boiling water
  • 2 oz. unsweetened chocolate, chopped
  • 1/2 cup unsalted butter, melted
  • 2 tablespoons vegetable oil
  • 2 large eggs
  • 2 large egg yolks
  • 2 teaspoons vanilla extract
  • 2 cups granulated sugar
  • 1 cup flour
  • 1 teaspoon salt
  • 4 oz. semi-sweet chocolate chunks

Instructions

  • Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving some overhang for easy removal later.
  • In a medium bowl, combine the unsweetened cocoa powder and boiling water. Stir well until the mixture is smooth and glossy. Set it aside to cool slightly.
  • In a separate bowl, melt the chopped unsweetened chocolate in the microwave in 30-second intervals, stirring between each interval until fully melted. Allow it to cool slightly.
  • In a large mixing bowl, whisk together the melted butter, vegetable oil, eggs, egg yolks, and vanilla extract until well combined. Add the cooled cocoa mixture and melted chocolate, mixing until smooth.
  • Sprinkle the flour, granulated sugar, and salt over the wet ingredients. Gently fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix!
  • Fold in the semi-sweet chocolate chunks, ensuring they're evenly distributed throughout the batter.
  • Pour the brownie batter into the prepared pan, spreading it evenly. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out with a few moist crumbs.
  • Allow the brownies to cool in the pan for about 10 minutes, then use the parchment overhang to lift them out. Let them cool completely on a wire rack before cutting into squares.
