Classic school cafeteria brownies with rich chocolate flavor and signature thin chocolate frosting. Nostalgic, easy to make, and always a crowd-pleaser.

Equipment

  • 9x13-inch baking pan
  • Electric hand mixer
  • Large mixing bowl
  • Parchment paper or aluminum foil
  • Rubber spatula

Ingredients
  

  • 1 cup salted butter, melted
  • 1/2 cup unsweetened cocoa powder
  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 4 large eggs beaten
  • 4 teaspoons vanilla extract
  • 1/4 cup salted butter, softened for frosting
  • 1/4 cup unsweetened cocoa powder for frosting
  • 1/4 cup milk 2% recommended, for frosting
  • 3 cups powdered sugar for frosting

Instructions
 

  • Preheat oven to 350°F. Line a 9x13 inch baking dish with parchment paper or foil, leaving overhang on sides. Lightly grease with cooking spray.
  • In a large bowl, combine 1 cup melted butter and 1/2 cup cocoa powder. Mix with electric hand mixer until completely smooth.
  • Add 2 cups flour and 2 cups sugar. Beat together, then add 4 eggs and 4 teaspoons vanilla. Mix just until combined. Batter will be thick.
  • Pour batter into prepared pan and spread evenly to all corners using a rubber spatula.
  • Bake 25-28 minutes until toothpick inserted in center comes out mostly clean with moist crumbs. Do not overbake.
  • While brownies bake, make frosting: Beat 1/4 cup softened butter, 1/4 cup cocoa powder, 1/4 cup milk, and 3 cups powdered sugar until smooth and creamy.
  • Remove brownies from oven and let stand 15 minutes. Frost while still warm for best results.
  • Spread frosting evenly over warm brownies. Let cool completely before cutting into squares.

Notes

  • For cleaner cuts, use a plastic knife and wipe between cuts
  • Brownies can be made 1-2 days ahead and stored covered at room temperature
  • Add 1 cup chopped walnuts to batter for extra crunch
  • Frosting too thick? Add milk 1 teaspoon at a time
  • For deeper chocolate flavor, use Dutch-processed cocoa powder
