  • 1 cup butter, melted
  • 6 eggs
  • 1 teaspoon vanilla
  • 1 teaspoon salt
  • 2 1/2 cups sugar
  • 6 tablespoons cocoa powder
  • 2 cups flour

Nutella Frosting

  • 3/4 cup butter, melted
  • 3 tablespoons Nutella (chocolate hazelnut spread)
  • 6 tablespoons milk
  • 2 - 2 1/2 cups powdered sugar


For Brownies:

  • In a large mixing bowl, place melted butter. (Make sure butter is slightly cooled before adding eggs.)  Add eggs, vanilla, and salt, and mix with a large wooden spoon.  *(see notes)
  • Add sugar and cocoa powder and mix well.  Add flour and mix just until combined.
  • Prepare a half sheet pan (about 13" x 18" pan) by greasing or coating with a non-stick spray. Pour brownie batter into pan and spread evenly.
  • Bake at 350F for about 20 minutes. Let cool a little before frosting.

For Nutella Frosting:

  • In a small bowl, place melted butter and Nutella. Stir until well-combined. **(see notes)  Add milk and mix.
  • Add powdered sugar until frosting reaches desired consistency. It should be thin enough to pour without being runny.
  • Pour frosting over brownies, and spread evenly. Let set for 10-30 minutes before cutting into about 40 squares.


*I recommend mixing these by hand rather than using a stand mixer. Stand mixers can add a lot of air into the batter, which will make the brownies more cakey. For the best texture, a large mixing bowl and wooden spoon are the best choice.
**I melted the butter about halfway, then added the Nutella and finished melting. This softened and melted the Nutella a bit, which made it easier to mix into the butter.
***If you don't want to use Nutella, substitute it for about 4 tablespoons of cocoa powder.
