Darkest Fudgy Walnut Brownies are simply irresistible. These brownies are made with melted butter, cocoa powder, and just a handful of other ingredients you are sure to have in your kitchen. They are incredibly easy, needing one bowl, 40 minutes, and your patience as the smell of rich chocolate fills your home.


  • 3/4 cup (165g) unsalted butter, melted
  • 2/3 cup (160g) light brown sugar
  • 2/3 cup (150g) granulated sugar
  • 3 large eggs (150g), room temperature
  • 2 teaspoons (8g) vanilla extract
  • 3/4 cup (105g) all purpose flour
  • 2/3 cup (60g) unsweetened cocoa powder
  • 1/2 teaspoon (4g) salt
  • 1 1/4 cups chocolate chunks
  • 1 1/4 cups chopped walnuts


  1. Preheat your oven to 350 degrees Fahrenheit. Line a 9 inch square pan with parchment paper, and spray with cooking spray.
  2. In a large bowl, whisk light brown sugar, granulated sugar, and eggs together for 2 minutes. Beat aggressively until the mixture becomes pale and shiny. This creates the shiny, crinkly tops on the brownies and is incredibly important. You may use a hand mixer for this part if preferred.
  3. Add vanilla extract and melted butter to the egg mixture, stirring until combined.
  4. Stir in flour, unsweetened cocoa powder, and salt. Once the dry ingredients begin to incorporate, fold in the chocolate chunks and walnuts to prevent overmixing. Stir until just combined.
  5. Bake for 28-35 minutes. Begin checking at the 25 minute mark, as all ovens and pans are different. The tops of the brownies will look set, and a toothpick inserted into the center will come out with moist crumbs and a bit of batter. Overbaking will lead to dry brownies. Let brownies set for at least one hour before cutting and serving.


If baking in an 8 inch pan or glass pan, the brownies will need to bake longer.
