These Brownies with Nutella Frosting have Nutella in both the batter AND the easy Nutella frosting for a double dose of your favorite chocolate hazelnut spread. 


Units Scale


  • 4 oz. bittersweet chocolate, chopped
  • 2 oz. milk chocolate, chopped
  • 6 oz. unsalted butter, cubed
  • 3/4 cup Nutella
  • 2/3 cup granulated sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • 1/4 teaspoon salt
  • 3/4 cup flour
  • 1/4 cup unsalted butter, softened
  • 1/3 cup Nutella
  • 1/4 teaspoon vanilla
  • 1 cup powdered sugar
  • 2 tablespoons whole milk
  • pinch salt


  1. Make brownies: Preheat oven to 350 °F. Line an 8x8 baking dish with parchment paper (or aluminum foil and spray lightly with non-stick cooking spray).
  2. Melt the chocolate together in the microwave in 30-second intervals, stirring every 30 seconds, until almost melted. Add butter and microwave for another 30 seconds, and stir until completely melted. Stir in Nutella, and let cool slightly.
  3. In a large bowl, whisk together the eggs and sugar until frothy and well combined.
  4. Add the vanilla and salt. Then, slowly incorporate the warm chocolate mixture. Gently stir in the flour by hand, careful not to overmix. 
  5. Bake brownies for approximately 30 minutes, or until a toothpick comes out with a few moist crumbs.
  6. Make the Nutella frosting: in a stand mixer with the paddle attachment, cream butter until smooth. Add other ingredients and beat until smooth.
  7. Let brownies cool completely before frosting and slicing.


  • Don't overcook the brownies! It's better to take them out when they are slightly underdone so they remain fudgy after they cool.
  • I like using a combination of milk chocolate and bittersweet chocolate for a flavor intensity that compliments the Nutella. But you can substitute all bittersweet, semisweet, or whatever you have on hand.
