These Ferrero Rocher Brownies are DANGEROUS! They are rich, fudgy, salty-sweet, and just how a frosted brownie should be. I frosted them with a smooth and fluffy Whipped Hazelnut Frosting.

How To Make Ferrero Rocher Brownies (basic steps)

Bake and Cool the Brownies. To your melted butter and sugar, whisk in eggs, unsweetened cocoa powder, salt, vanilla. Fold in all purpose flour, baking powder, Ferrero Rochers and hazelnuts. Bake for 25 minutes and cool to room temperature.

Make the Whipped Hazelnut Frosting. Whip together unsalted butter, hazelnut spread, and vanilla. Add the unsweetened cocoa powder, powdered sugar, and salt. Whip on until light and fluffy.

Frost Your Brownies. Using an offset spatula apply an even layer of Whipped Hazelnut Frosting to the cooled brownie.

Sprinkle Toppings on the Brownies. Feel free to decorate your Ferrero Rocher Brownies any way you want.

Cut and Serve. Best cut into 9 or 12 pieces. Be prepared because these Ferrero Rocher Brownies will be gone SO FAST!

3 Tips For The BEST Brownies

  1. Allow the butter and sugar to boil together until it becomes a bubbly, white mixture when you are making the brownies. By doing this you will get that beautiful, shiny top everyone loves. So if your mixture looks like separated butter and sugar let it keep boiling.
  2. Frost the brownies when they are completely cooled. If the brownies are still warm, the frosting will just melt off of them. If you need your brownies to cool quicker you can always pop them in the refrigerator or freezer until they are cooled.
  3. For a “clean cut” brownie, throw them in the refrigerator for an hour to chill. Grease your knife with cooking spray and cut straight down (do not saw). Between cuts, wipe the knife clean and respray.
