Instructions

Fudgy, Nutella brownies

  • Preheat the oven to 350F and line & spray an 8×8 baking pan with parchment paper, leaving an overhang to easily remove brownies after baked
  • In a large microwave-safe bowl, combine the milk chocolate chips, dark/unsweetened Belgian chocolate and butter. Heat on 50% power or the defrost setting for 1 minute then remove and stir. Continue heating in 15-30-second intervals until the mixture is completely melted & smooth. Be careful not to overheat.

  • Pour the brownie batter into the prepared baking pan and bake for 35-40 minutes. You want to bake until a toothpick or tester comes out with moist crumbs still attached.
  • Let cool to room temperature.

Nutella Buttercream

  • Mix butter on medium-high speed using the paddle attachment on a stand mixer until light and fluffy.
  • Add the Nutella, Frangelico (or vanilla) and mix for 1 minute more.
    3/4 cup Nutella, 1 tbsp Frangelico or 1/2 tsp pure vanilla extract
  • Add the powdered sugar (starting with 4.5 cups), the cocoa powder and 6 tbsp of whipping cream and mix on low to combine.
    3-4 cups powdered sugar, 1/4 cup cocoa powder, 6-8 tbsp heavy whipping cream
  • Incorporate all the ingredients together by scraping down the sides and bottom of bowl using a silicone spatula and mix on medium until frosting is smooth and creamy. Adjust to desired consistency by adding whipping cream to thin it out or powdered sugar to thicken it.

Assembly

  • Transfer Nutella buttercream to a pastry bag fitted with a star tip.

  • Once the brownies have fully cooled, pipe the buttercream onto the top of your brownies by holding your piping bag at a 90 degree angle over the brownies. Squeeze a small burst of pressure, release and quickly pull upwards. Repeat until brownies are fully covered. Or ice using a spatula.
