Ingredients

Units Scale
For the Brownies:
  • 1 cup unsalted butter, melted
  • 1/2 cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 1/2 cups all-purpose flour
  • 1/4 teaspoon salt
For the Frosting:

  • 1/4 cup unsalted butter, softened
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup milk
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat & Prep: Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper.
  2. Make the Batter: In a large bowl, whisk together melted butter and cocoa powder until smooth. Add sugar and mix well.
  3. Add Eggs & Vanilla: Beat in eggs one at a time, then add vanilla extract. Stir until combined.
  4. Finish the Batter: Gently fold in flour and salt until just mixed (do not overmix).
  5. Bake: Pour batter into the prepared pan and bake for 25–30 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.
  6. Make the Frosting: While the brownies bake, beat together softened butter, cocoa powder, milk, powdered sugar, and vanilla until smooth and spreadable.
  7. Frost & Set: Once brownies are slightly cooled but still warm, spread the frosting evenly over the top. Let cool completely before slicing.
  8. Serve & Enjoy: Cut into squares and serve!

Notes

  • Extra Fudgy? Slightly underbake them and let them cool in the pan.
  • Thicker Frosting? Add more powdered sugar.
  • Storage: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week.
